When a pulse reaches the surface of the material it is measuring, part of the energy is reflected back to the transmitter, and the time difference between the generated and reflected pulse is converted into a distance from which the total level or interface level is calculated (see below). The reflectivity of the product is a key parameter for measurement performance. A high dielectric constant of the media gives better reflection and a longer measuring range. A calm surface gives better reflection than a turbulent surface.Figure 2-1. Measurement Principle.APPLICATION EXAMPLES The Rosemount 3308 transmitter is suited for aggregate (total) level measurements on most liquids, semi-liquids, and liquid/liquid interfaces.Guided microwave technology offers highest reliability and precision which ensure measurements are virtually unaffected by temperature, pressure, vapor gas mixtures, density, turbulence, bubbling/boiling, low level, varying dielectric media, pH, and viscosity.Guided wave radar technology in combination with advanced signal processing make the Rosemount 3308 transmitter suitable for a wide range of applications.TimeReference PulseLevelInterface LevelSignal Amplitude

It can be equipped with probes that are unaffected by high and narrow openings or nearby objects.Small ammonia, NGL and LPG tanksGuided wave radar technology is a good choice for reliable measurements in small ammonia, NGL and LPG tanks.
Reference Manual00809-XXXX-4811, Rev AAFebruary 2012Rosemount 33082-6PRELIMINARYSYSTEM ARCHITECTURE The Rosemount 3308 transmitter is battery powered with wireless communication which means the unit works completely independent.By using the optional HART Tri-loop, it is possible to convert the HART signal to up to three additional 4-20 mA analog signals.With the HART protocol it is possible to use multidrop configuration. In this case communication is restricted to digital since current is fixed to the 4 mA minimum value. The transmitter can be connected to display Rosemount 751 Field Signal Indicator or it can be equipped with an integral display.The transmitter can easily be configured by using the AMS suite software or by using a Field Communicator. A PC with the Radar Configuration Tool software can also be used for configuration.For HART communication a minimum load resistance of 250  within the loop is required.Figure 2-2.

Reference Manual 00809-XXXX-4811, Rev AAFebruary 20122-7Rosemount 3308PRELIMINARYInterface Rosemount 3308 is the ideal choice for measuring the interface of oil and water, or other liquids with significant dielectric differences.Figure 2-3. Interface measurement with a Rosemount 3308All probes can be used for measuring interfaces. The coaxial probe is the preferred choice for clean liquids and when the bridle is not fully immersed. In applications with a fully immersed probe, the twin lead probes are recommended for nozzle installations, and the rigid single lead probe is best for bridle mounting.For measuring the interface level, the transmitter uses the residual wave of the first reflection. Part of the wave, which was not reflected at the upper product surface, continues until it is reflected at the lower product surface. The speed of this wave depends fully on the dielectric constant of the upper product.If interface is to be measured, the following criteria have to be fulfilled:• The dielectric constant of the upper product must be known. The Radar Configuration Tools software has a built-in dielectric constant calculator to assist users in determining the dielectric constant of the upper product.• The dielectric constant of the upper product must have a lower dielectric constant than the lower product in order to have a distinct reflection.• The difference between the dielectric constants for the two products must be larger than 10.• Maximum dielectric constant for the upper product is 10 for the coaxial probe and 5 for twin lead probes.• The upper product thickness must be larger than 8 inches (0.2 m) for the flexible twin lead probe and 4 inches (0.1 m) for the rigid twin lead and coaxial probes in order to distinguish the echoes of the two liquids.The maximum allowable upper product thickness/measuring range is primarily determined by the dielectric constants of the two liquids. Target applications include interfaces between oil/oil-like and water/water-like liquids. For such applications the upper product dielectric constant is low (<3) and the lower product dielectric constant is high (>20), and the maximum measuring range is only limited by the length of the coaxial and rigid twin lead probes.LevelInterface Level Level = Interface Level

Reference Manual 00809-XXXX-4811, Rev AAFebruary 20122-9Rosemount 3308PRELIMINARYVESSEL CHARACTERISTICSHeating Coils, Agitators The Rosemount 3308 transmitter is relatively insensitive to objects in the tank since the radar signal is transmitted along a probe. Avoid physical contact between probes and agitators as well as applications with strong fluid movement unless the probe is anchored. If the probe can move within 1 ft (30 cm) away from any object, such as an agitator, during operation then probe tie-down is recommended.In order to stabilize the probe for side forces, it is possible to hang a weight at the probe end (flexible probes only) or fix/guide the probe to the tank bottom.Tank Shape The guided wave radar transmitter is insensitive to the tank shape. Since the radar signal travels along a probe, the shape of the tank bottom has virtually no effect on the measurement performance. The transmitter handles flat or dish-bottom tanks equally well.

For interface measurements the dielectric constant of the top liquid must also be given. For some applications with heavy vapor, the vapor dielectric must be given as well.Figure 5-3.

Reference Manual00809-XXXX-4811, Rev AAFebruary 2012Rosemount 33085-4PRELIMINARYTank HeightThe Tank Height is the distance from the Upper Reference Point to the bottom of the tank. The transmitter measures the distance to the product surface and subtracts this value from the Tank Height to determine the level.Probe LengthThe probe length is the distance between the Upper Reference Point and the end of the probe. If a weight is used at the end of the probe it shall not be included.This parameter is pre-configured at factory. It must be changed if the probe is shortened.Probe TypeThe transmitter is designed to optimize measurement performance for each probe type. This parameter is pre-configured at factory. This value needs to be changed if the probe type is changed.Dielectric Constant of Upper ProductFor interface measurements the dielectric constant of the upper product is essential in order to obtain good accuracy. See section “Interface” on page 2-7 for further information on dielectric constants. If the dielectric constant of the lower product is significantly smaller than the dielectric constant of water, you may need to make special adjustments. See section “Interface Measurements for Semi-Transparent Bottom Products” on page 7-5 for further information. For level measurements the Upper Product Dielectric parameter corresponds to the actual dielectric constant of the product in the tank. Normally this parameter does not need to be changed even if the actual dielectric constant of the product deviates from the Upper Product Dielectric parameter value. However, for some products measurement performance can be optimized by setting the proper product dielectric constant.Dielectric Constant of VaporIn some applications there is heavy vapor above the product surface having a significant influence on the level measurement. In such cases the vapor dielectric can be entered to compensate for this effect.The default value is equal to 1 which corresponds to the dielectricity of vacuum. Normally this value does not need to be changed since the effect on measurement performance is very small for most vapors.
Reference Manual 00809-XXXX-4811, Rev AAFebruary 20125-5Rosemount 3308PRELIMINARYUpper Null ZoneThis parameter should only be changed if there are measurement problems in the upper part of the tank. Such problems may occur if there are disturbing objects close to the probe. By setting the Upper Null Zone, the measuring range is reduced. See Section 7: Disturbances at the Top of the Tank for further information.NOTEMeasurements are not performed within the Upper Null Zone. Probe angleIf the transmitter is not mounted vertically, the angle from the vertical position must be given.

Choose None if volume calculation is not used.Tank TypeYou can choose one of the following options:• Strap table• Vertical Cylinder• Horizontal Cylinder• Vertical Bullet• Horizontal Bullet• Sphere•NoneStrapping TableUse a strapping table if a standard tank type does not provide sufficient accuracy. Use most of the strapping points in regions where the tank shape is non-linear. A maximum of 10 points can be added to the strapping table.Figure 5-5. Strapping pointsActual tank bottom may look like this.Using only 3 strapping points results in a level-to-volume profile that is more angular than the actual shape.Using 6 of the points at the bottom of the tank yields a level-to-volume profile that is similar to the actual tank bottom.

The transmitter outputs a digital HART wireless signal.Transmitter VariablesYou may assign up to four transmitter variables. Typically, the primary variable (PV) is configured to be Aggregate Level, Interface Level or Volume. Measurement UnitsSet transmitter units for level and temperature.Tank HeightThe Tank Height is the distance from the Upper Reference Point to the bottom of the tank (see Figure 5-3 on page 5-3). When setting the Tank Height, keep in mind that this value is used for all level measurements performed by the Rosemount 3308 transmitter. The Tank Height must be set in linear (level) units, such as feet or meters, regardless of primary variable assignment.Probe LengthThe probe length is the distance from the Upper Reference Point to the end of the probe, see Figure 5-3. If the probe is anchored to a weight do not include the height of the weight. This parameter is pre-configured at factory. The Probe Length needs to be changed if, for example, the probe is shortened.HART Comm TO BE ADDEDHART Comm TO BE ADDEDHART Comm TO BE ADDEDHART Comm TO BE ADDED
Reference Manual00809-XXXX-4811, Rev AAFebruary 2012Rosemount 33085-10PRELIMINARYProbe TypeThe transmitter automatically makes an initial calibration based on the type of probe that is used. This parameter is pre-configured at factory and only needs to be set if the probe is changed to another type. Choose one of the following options:• Flexible Twin•Coaxial• Rigid Single, Rigid Single PTFE• Flexible Single, Flexible Single PTFEProduct DielectricFor interface measurements the dielectric constant of the upper product is essential for calculating the interface level and the upper product thickness. By default the Product Dielectric parameter is about 2. If the dielectric constant of the lower product is significantly smaller than the dielectric constant of water, you may need to make special adjustments. See section “Interface Measurements for Semi-Transparent Bottom Products” on page 7-5 for further information.The dielectric constant of the product is used for setting the appropriate signal amplitude thresholds, see Section 7: Service and Troubleshooting for more information on amplitude threshold settings. Normally this parameter does not need to be changed for level measurements. However, for some products measurement performance can be optimized by setting the proper product dielectric constant.The AMS Suite software includes a Dielectric Chart which lists the dielectric constants of a wide range of products. AMS also includes a tool which allows you to calculate dielectric constants based on measurements of the Upper Product Thickness.Vapor DielectricIn some applications there is heavy vapor above the product surface having a significant influence on the level measurement. In such cases the vapor dielectric can be entered to compensate for this effect.The default value is equal to 1 which corresponds to the dielectric constant of vacuum.

In this mode the transmitter ignores the upper product level. See Section 7: Interface Measurements with Fully Immersed Probes for more information.NOTE!Only use Interface Immersed Probe for applications where interface is measured for a fully immersed probe.Probe AngleEnter the angle between the probe and the vertical line. The default value is equal to zero. Do not change this value if the transmitter is mounted with the probe along the vertical line (which is normally the case).Maximum Upper Product Thickness For interface measurements the Maximum Upper Product Thickness parameter may be used in special cases when the dielectric constant of the upper product is relatively high.

Figure 7-1. Tank GeometryTo set the desired upper reference point do the following:1. Adjust the Tank Height to the distance from the tank bottom to the desired Upper Reference Point.2. Add the distance between the Upper Reference Point and the Transmitter Reference Point to the Calibration Offset value that is stored in the transmitter database. With the HART Communicator the Calibration Offset is available as HART Fast Key sequence [1, 4, 5, 5].In Radar Configuration Tool (RCT) the Calibration Offset is available under the Advanced section in the RCT Project Bar:Device Commands>Basic>Set Calibration Offset.Tank HeightProduct LevelUpper Reference Point Transmitter Reference PointCalibration Offset
Reference Manual 00809-XXXX-4811, Rev AAFebruary 20127-3Rosemount 3308PRELIMINARYPlotting the Measurement Signal The Radar Configuration Tool (RCT) has powerful tools for advanced troubleshooting. By using the Waveform Plot function you get an instant view of the tank signal. Measurement problems can be solved by studying the position and amplitude of the different pulses.To plot the measurement signal:1. Start the Radar Configuration Tool program.2. Choose the View>Plotting menu option, or choose the Plotting icon in the RCT workspace (Advanced page at the left side of the workspace) and click the Read  button.Figure 7-2. Waveform plot in RCTIn a typical measurement situation the following pulses appear in the diagram:P1 - Reference pulse. This pulse is caused by the transition between transmitter head and probe. It is used by the transmitter as a reference at level measurements.P2 - Product surface. This pulse is caused by a reflection on the product surface. In Measurement Mode=Interface when Immersed Probe however, P2 indicates the interface since the surface of the upper product is ignored.P3 - Interface or probe end. This pulse is caused by reflection on the interface between an upper product and a bottom product with a relatively high dielectric constant. It may also be caused by the probe end if there is no product above. This pulse is shown when the transmitter is in Measurement Mode=Level & Interface.Different amplitude thresholds are used in order to filter out unwanted signals. The following amplitude thresholds are used for the Rosemount 3308 transmitter:T1 - amplitude threshold for detection of the Reference pulse P1.T2 - amplitude threshold for detection of the product level peak P2.T3 - amplitude threshold for detection of the interface level peak P3.T4 - amplitude threshold that is used to detect whether the probe is fully immersed in the upper product or not. -Upper Null Zone
Reference Manual00809-XXXX-4811, Rev AAFebruary 2012Rosemount 33087-4PRELIMINARYNormally the thresholds are adjusted to approximately 50% of the signal peak amplitude. To adjust the Amplitude Thresholds open the Advanced section in the RCT Project Bar and choose Device Commands>Details>Set Nominal Thresholds. To reset the default values set Amplitude Threshold=0 (zero).Logging and saving to diskThe Waveform plot can be automatically logged and saved to file by specifying the read plot interval and the number of plots to log.Figure 7-3. Disk logging Waveform plotThe Read Plot Interval entry field specifies the time interval between plots that are saved to disk. For example, type 10 if you want the waveform plot to be updated every ten minutes.Number of plots to log specifies the maximum number of plot files that will be stored. The default value is 100.Click the Start Disk Logging button to start the log. Make sure that Read Action type is set to Multiple Read. Otherwise RCT will only save one log file.

Reference Manual 00809-XXXX-4811, Rev AAFebruary 20127-5Rosemount 3308PRELIMINARYInterface Measurements for Semi-Transparent Bottom ProductsIn interface applications where the bottom product has a low dielectric constant, or if the signal is attenuated in the upper product, the amplitude of the reflected signal is relatively low and difficult for the transmitter to detect. In such a case it may be possible to detect the reflected signal if the corresponding amplitude threshold is adjusted.The Radar Configuration Tool (RCT) lets you view a waveform plot to analyze the measurement signal. The plot shows the signal and the thresholds used for the different amplitude peaks. By adjusting amplitude threshold T3 it is possible to detect even weak interface signals. Guidelines for amplitude threshold settings:• The amplitude threshold T3 should be approximately 50 % of the interface signal amplitude.• Threshold T3 should not be less than 3.• If possible, T3 should be higher than T2.You can use the RCT software or a Field Communicator to change the amplitude thresholds. For the Field Communicator use the HART command [1, 4, 5, 3]. See also “Amplitude Threshold Settings” on page 7-12.RCT lets you view a plot of the measurement signal along with the current thresholds:1. From the View menu choose the Plotting option, or double-click the Plotting icon in the Advanced section of the RCT Project Bar. 2. Click the Read button  .3. To adjust the Amplitude Thresholds open the Advanced section in the RCT Project Bar and choose Device Commands>Details>Set Nominal Thresholds.Figure 7-4. Waveform plot indicating that the amplitude threshold for the interface peak is too high.The amplitude threshold is above the measurement signal peak
Reference Manual00809-XXXX-4811, Rev AAFebruary 2012Rosemount 33087-6PRELIMINARYFigure 7-4 illustrates a situation where amplitude threshold T3 is too high. The signal amplitude peak at the interface between the upper and lower products is not detected in this case. By adjusting amplitude threshold T3, the peak at the interface between the upper and lower products is detected as illustrated in Figure 7-5:Figure 7-5. After changing the amplitude threshold the transmitter detects the interface The amplitude threshold is adjusted below the peak to allow the interface peak to be detected
Reference Manual 00809-XXXX-4811, Rev AAFebruary 20127-7Rosemount 3308PRELIMINARYHigh Level Rates The measurement signal is filtered in order to minimize the influence of disturbing noise. In most measurement situations this does not have a noticeable effect on the response time to level changes. If high level rates occur it may however be necessary to reduce the damping value in order to allow the transmitter to respond quicker. If there is too much noise the damping value may be increased in order to get a stable measurement signal.You can use the RCT software or a Field Communicator to change the Damping value. For the HART Communicator use the key sequence [1, 3, 5]. In the RCT software open the Setup>Output tab and enter the desired Damping value:The Damping parameter determines how quickly the transmitter responds to level changes and how robust the measurement signal is against noise. Technically, a damping value of 10 means that in 10 seconds the output from the transmitter is about 63% of the new level value. Consequently, when there are rapid level changes in the tank, it may be necessary to decrease the Damping value for the transmitter to be able to track the surface. On the other hand, in noisy environments, and if level rates are low, it may be better to increase the damping value to have a stable output signal.DampingOutput tab
Reference Manual00809-XXXX-4811, Rev AAFebruary 2012Rosemount 33087-8PRELIMINARYInterface Measurements with Fully Immersed ProbesThe Rosemount 3308 transmitter has a measurement option which makes it possible to handle interface measurements when the product level is not visible, for example in a full bridle pipe as illustrated in Figure 7-6. In this case the probe is fully immersed into the upper product, and only the interface level is detected by the transmitter. Even if the upper product level drops, it is ignored by the transmitter which continues to measure only the interface level, but the measurement accuracy is reduced since the transmitter does not take into account the influence of the air gap above the product surface. The Measurement Mode parameter is available via the HART command [1, 3, 3, 4]. Choose the Interface when Immersed Probe option.Measurement mode Interface when Immersed Probe can also be activated in the RCT software:1. Open the Setup window.2. Select the Tank Config tab.3. Choose Measurement Mode Interface when Immersed Probe.4. Click the Send Page button.NOTE!Do not use Measurement Mode Interface when Immersed Probe in “standard” applications when both Interface Level and Product Level are measured.If the product level drops, the air filled region in the upper part of the pipe will slightly reduce the measurement accuracy of the interface level. To achieve high accuracy in this measurement mode the probe must be fully immersed.Figure 7-6.

Calibrate the Distance measurement by adjusting the Calibration Offset parameter.2. Calibrate the Level measurement by adjusting the Tank Height.Distance calibration1. Measure the actual distance between the Upper Reference Point and the product surface.2. Adjust the Calibration Offset so that the Distance measured by the transmitter corresponds to the actual distance.

Reference Manual00809-XXXX-4811, Rev AAFebruary 2012Rosemount 33087-10PRELIMINARYDisturbances at the Top of the Tank Using the Trim Near Zone FunctionFor transmitters using the Guided Wave Radar technology the performance In the Near Zone (referred to as the region between 0-1.6 ft (0-0.5 m) below the Upper Reference Point) is normally somewhat limited. However, the Rosemount 3308 transmitter is equipped with software functionality that minimizes the Upper Transition Zone. The factory setting is normally sufficient and doesn’t need to be repeated after installation. However, since the setting is optimized depending on actual installation, further trimming may be necessary in the case of unfavorable conditions. This may for example be the case if a Single Lead probe is mounted in a small nozzle, or if there are disturbing obstacles in the Near Zone. The trimming means that the measurement performance in the Near Zone is maintained even under these conditions and prevents false echo indication.To trim the Near Zone performance do the following:1. Make sure that the product level is below the Near Zone region (0-1.6 ft (0-0.5 m) below the Upper Reference Point).2. Start the Radar Configuration Tools (RCT).3. Choose the Device Commands option from the View menu.4. Open the Details folder.5. Click the Trim Near Zone option.6. Select the Update option and click the OK button.NOTE!The Trim Near Zone function should only be used for reducing impact from constant disturbances. It is not suitable for occasional disturbances.To reset the transmitter to factory settings do the following:1. Start the Radar Configuration Tools (RCT).2. Choose the Device Commands option from the View menu.3. Open the Details folder.4. Click the Trim Near Zone option.5. Select the Reset to Factory Settings option and click the OK button.Changing the Upper Null ZoneMeasurements are not performed within the Upper Null Zone (UNZ). By setting the UNZ parameter to zero, measurements can be performed in the region close to the flange (Near Zone). However, it is very important that there are no disturbances in that region if UNZ is set to zero.If there are measurement problems in the upper part of the tank you may use the Trim Near Zone function as described above.If the desired measurement range is below the Near Zone, or if disturbing objects are located below the Near Zone, the Upper Null Zone parameter can be used to avoid measurements above a certain level.

Reference Manual00809-XXXX-4811, Rev AAFebruary 2012Rosemount 33087-12PRELIMINARYAmplitude Threshold Settings The amplitude thresholds are automatically adjusted to appropriate values in order to filter out noise and other non-valid measurements from the measurement signal.The amplitude of the measurement signal, i.e. the amplitude of the signal that is reflected by the product surface, is related to the actual dielectric constant of the product. The amplitude threshold that is used by the transmitter is based on the parameter configuration of the current product dielectric constant (see Section 5: Basic Configuration). Normally no other threshold adjustment is needed, but if the transmitter still does not track the product surface correctly it may be necessary to adjust the threshold values.The Radar Configuration Tool (RCT) has a plot function allowing you to view the reflections along the probe.If the amplitude threshold is too high the product level is not detected as illustrated in Figure 7-10.Figure 7-10. Example 1: amplitude threshold T2 is too high.If there are disturbing objects in the tank the threshold must be carefully set in order to avoid locking on the wrong amplitude peak. In Figure 7-11 the transmitter has locked on a peak above the actual product surface, i.e. a disturbance was interpreted as the product surface, whereas the actual product surface was interpreted as an interface or the probe end.

It is also possible to measure interfaces with a Rosemount 3308 in applications where the probe is fully submerged in the liquid. If interface is to be measured, follow these criteria:• The dielectric constant of the upper product must be known and should not vary. The Radar Configuration Tools software has a built-in dielectric constant calculator to assist the user in determining the dielectric constant of the upper product• The dielectric constant of the upper product must have a lower dielectric constant than the lower product to have a distinct reflection• The difference between the dielectric constants for the two products must be larger than 10• Max. dielectric constant for the upper product is 10 for the coaxial probe and 5 for twin lead probes• The upper product thickness must be larger than 8 in. (0.2 m) for the flexible twin lead probe;4 in. (0.1 m) for the rigid twin lead, and coaxial probes in order to distinguish the echoes of the two liquids• Sometimes there is an emulsion layer (mix of the products) between the two products which can affect interface measurements.

If measurements are desired at the very top of a tank, it is possible to mechanically extend the nozzle and use a coaxial probe. The upper transition zone is then moved into the extension. See Table A-3 on page A-7.Measuring Range and Minimum Dielectric Constant 16 in. (0.4 m) to 77 ft. (23.5 m)See Table A-4 on page A-7 for each probe’s measuring range and minimum dielectric constant. Due to the measuring range depending on the application and factors described below, the values are a guideline for clean liquids. For more information, ask your local Emerson Process Management representative.Different parameters (factors) affect the echo and therefore the maximum measuring range differs depending on application according to:• Disturbing objects close to the probe• Media with higher dielectric constants (r) give better reflection and allow a longer measuring range• Surface foam and particles in the tank atmosphere may affect measuring performance• Heavy coating or contamination on the probe should be avoided since it can reduce measuring range and might cause erroneous level readingsNote: See Table A-5 on page A-7 for the measuring range when using the Remote Housing.Interface Measuring Range Target applications include interfaces between oil; oil-like and water; and water-like liquids with a low (<3)upper product dielectric constant and a high (>20) lower product dielectric constant. For such applications, the max measuring range is only limited by the length of the coaxial, rigid twin and rigid single lead probes.Note: For other product combinations, consult your local Emerson Process Management representative.EnvironmentVibration Effect Wireless output unaffected when tested per the requirements of IEC60770-1 field or pipeline with high vibration level (10-60 Hz 0.21 mm displacement peak amplitude / 60-2000 Hz 3g).Wireless output unaffected when tested per the requirements of IEC60770-1 field with general application or pipeline with low vibration level (10-60 Hz 0.15 mm displacement peak amplitude / 60-500 Hz 2g).Electromagnetic Compatibility (EMC) Meets all relevant requirements of EN 61326-2-3:2006Built-in Lightning Protection Meets EN 61000-4-4 Severity Level 4 and EN 61000-4-5 Severity Level 4Upper Reference PointUpper Transition ZoneMaximum Recommended Measuring RangeLower Transition ZoneLower Reference PointLower Transition ZoneFor a flexible single lead probe with chuck, the lower transition zone is measured upwards from the upper part of the clamp.Lower Transition Zone
Reference Manual00809-XXXX-4811, Rev AAFebruary 2012Rosemount 3308A-6PRELIMINARYCoating The Rosemount 3308 has a high sensitivity due to its advanced signal processing and high signal to noise ratio, which makes it able to handle various disturbances. However, the following circumstances should beconsidered before mounting the transmitter.• Single lead probes are preferred when there is a risk for contamination (because coating can result in product bridging across the two leads for twin versions; between the inner lead and outer pipe for the coaxial probe)• PTFE probes are recommended for viscous or sticky applications. Periodic cleaning might be required• Maximum error due to coating is 1 to 10% depending on probe type, dielectric constant, coating thickness, and coating height above product surfaceCoating on the probe should be avoided since the sensitivity of the transmitter may be decreased leading to measurement errors. In viscous or sticky applications, periodic cleaning may be required.For viscous or sticky applications, it is important to choose a suitable probe (see Table A-6 on page A-7).Bridging Heavy coating that results in product bridging across the two probes for twin lead versions, or between the pipe and the inner rod for coaxial probes, will cause erroneous level readings and must be prevented. Single lead probes are preferred in this case. If a Twin Lead probe is required, regular cleaning may be necessary.Foam How well the Rosemount 3308 transmitter measures in foamy applications depends upon the properties of the foam; light and airy or dense and heavy, high or low dielectrics, etc. If the foam is conductive and creamy the transmitter will probably measure the surface of the foam. If the foam is less conductive the microwaves will probably penetrate the foam and measure the liquid surface.Vapor In some applications, as ammonia, there is heavy vapor above the product surface that will influence the level measurement. The Rosemount 3308 transmitter can be configured to compensate for the influence of vapor.CE-mark

The probe should be centered to prevent it touching the sides of the well.The probe length determines if a Single Rigid or Single Flexible probe should be used:• Less than 19.7 ft. (6.0 m):Rigid Single Probe is recommended. Use a centering disc for probe > 3.3 ft. (1 m). If installation requires less head-space, use a Flexible Single Probe with a weight and centering disc.• More than 19.7 ft. (6.0 m):Use Flexible Single Probe with a weight and centering disc.A short weight is available for the single flexible SST probe. It is used for measuring close to the probe endand shall be used where the measuring range must be maximized. The height is 2 in. (50 mm) and the diameter is 1.5 in. (37.5 mm). The option code is W2.If a heavier weight is needed, option code W3 can be used (height is 5.5 in. (140 mm) and the diameter is 1.5 in. (37.5 mm).Centering Discs To prevent the probe from contacting the chamber or pipe wall, centering discs are available for rigid single, flexible single, and flexible twin lead probes. The disc is attached to the end of the probe. Discs are made of stainless steel, Alloy C-276, Alloy 400, or PTFE. See Table A-9 for Dimension D. Table A-10 shows which centering disc diameter to choose for a particular pipe.DCoaxial Rigid Twin Lead Flexible Twin Lead Rigid Single Lead Flexible Single LeadRecommended nozzle diameter Enough space to fit the probe(1) 4 in.

Information that raises potential safety issues is indicated by a warning symbol ( ). Please refer to the following safety messages before performing an operation preceded by this symbol.Explosions could result in death or serious injury:Verify that the operating environment of the gauge is consistent with the appropriate hazardous locations certifications.Before connecting a HART-based communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.In an Explosion-proof/Flameproof installation, do not remove the transmitter cover when power is applied to the unit.Failure to follow safe installation and servicing guidelines could result in death or serious injury:Make sure the transmitter is installed by qualified personnel and in accordance with applicable code of practice.Use the equipment only as specified in this manual. Failure to do so may impair the protection provided by the equipment.Do not perform any service other than those contained in this manual unless you are qualified.A safety isolator such as a zener barrier is always needed for intrinsic safety.
Reference Manual00809-XXXX-4811, Rev AAFebruary 2012Rosemount 3308B-2PRELIMINARYPLACEHOLDER FOR APPROVALS INFORMATIONHigh voltage that may be present on leads could cause electrical shock:Avoid contact with leads and terminals. Make sure the main power to the Radar Transmitter is off and the lines to any other external power source are disconnected or not powered while wiring the transmitter.Probes covered with plastic and/or with plastic discs may generate an ignition-capable level of electrostatic charge under certain extreme conditions. Therefore, when the probe is used in a potentially explosive atmosphere, appropriate measures must be taken to prevent electrostatic discharge.
