![ 18 6 F 8 A 0 7 8 7Hoisting the Density Meter Before InstallationMake sure to hoist the density meter using the hoisting bands.Hoisting it with incomplete position or condition can cause a fall or damage to the density meter.When you move or install the Insertion Type Density Meter, make sure to hoist the density meterusing the hoisting bands. In addition, care should be taken to put the cushioning material between thehoisting band and the converter case. If the hoisting band touches the converter case directly it maycause a scratch on the converter front panel.Main unit mass: approx. 20 kgRecommended hoisting bands: made of cloth, applicable band size 25 mmNote: This unit is heavy. To move the unit or relocate it needs a qualified operator for handling a handtruck, crane, hoist or other. In addition, when hoisting the unit with hoisting bands, tighten thebands so that the bands will not be loosened or slipped off.吊り上げ方向吊りベルト装着位置重心位置[NOTE]吊り上げ方向吊りベルト装着位置重心位置Hoisting directionHoisting position with bandCenter of gravity positionFig. 3.1.1 Hoisting with Hoisting Bands (1) Fig. 3.1.1 Hoisting with Hoisting Bands (2)Hoisting directionCenter ofgravity positionHoisting positionwith band](https://usermanual.wiki/Toshiba/62372311/User-Guide-231580-Page-20.png)
![ 19 6 F 8 A 0 7 8 73.2 Installation Location◆Determine an indoor installation place in accordance with the following instructions.(1) Choose a place that is free of vibrations and corrosive gasses, and has ample space formaintenance.(2) Secure maintenance space in front, rear and above the density meter. (Refer to fig. 3.2.1)(3) In the case of outdoor installation, provide covering against sun.(4) Do not install the meter in a place where there is a possibility of leakage of flammable orexplosive gas.(5) Use a strength pipe, connected at both upstream and downstream sides, to securelyinstall the detector main body, or provide a supporting structure for the detector mainbody. (Weight of this unit is shown in the external dimension list as attached.)(6) When the density meter is used in an application where the process fluid contains plentyof fur or fiber, these substances may accumulate or entangle in the density meter and thusperform the maintenance operation periodically (clean the insertion probe area).(7) The tank or pipe where this density meter is installed should be metal.(8) Install the density meter in a place where the density distribution is even. If the densitydistribution is not even, manual analysis data and the indication value of the density metermay not be the same.(9) Install this density meter in a piping system where bubbles are not found, and fluid doesnot empty itself, and also sedimentation and accumulation of materials does not occur.[NOTE]](https://usermanual.wiki/Toshiba/62372311/User-Guide-231580-Page-21.png)
![ 21 6 F 8 A 0 7 8 73.3 Installation and PipingInstalling the density meter is illustrated in Fig. 3.3.1 and Fig. 3.3.2, Fig.3.3.3, Fig.3.3.4.<Common Precautions>(1) Install the density meter in a place where the distribution of density is even.(2) Install the density meter in a location where the measured fluid flows in a tank or pipe in full and bubblesdo not stay. Insufficient fluid flowing or bubbles staying in the tube will cause measuring errors orindicated-value fluctuations.(3) Avoid installing the density meter where the material to be measured precipitates and accumulates atthe bottom of the tank or pipe.(4) Avoid installing the density meter in a tank or pipe where bubbles are mixed in the fluid to be measured.(5) The front side of the density meter's converter section is equipped with an LED density display section.When installing the meter, choose a location and direction in which this density display section will beeasily visible. However, if it is difficult to look straight at the density value display area as a result ofinstallation layout, we recommend you order an optional external display unit.(6) In the event that the tank or piping system (where the density meter is installed) may no longer be full ofthe fluid while the pump is shut down or the density distribution in the density meter may becomeuneven, make sure to take measurements only while the pump is operating by using the externalinterlock function.(7) Take necessary measures to prevent vibrations of the pump, etc. from travelling through the densitymeter.(8) Select the type and material of the gasket to use in the tank or pipe in accordance with the connectionmethod and the fluid material to measure.(9) Make sure that the surface for the O-ring face and O-ring itself are clean without dirt or dust beforestarting the installation work.(10) We recommend the following tightening torque for bolts and nuts when mounting the flange for thedensity meter. Tightening torque: 10.0 to 13.5 N•m for M8 bolts and nuts(11) Perform the periodical inspection to make sure that the thin and long materials such as fur, fiber orstrings are not entangled in the applicators (antenna), or there are no scratches or cracks.(12) Make sure that the applicator (antenna) is positioned more inside than the internal wall of the tank orpipe. The distance from the mounting flange face of the insertion probe area to the internal wall shouldbe 120 mm or less.<Piping Precautions>(13) We recommend the installation should be made to a vertical piping system. The density meter canoperate the same performance even in a horizontal installation but only a vertical installation is allowedfor item (14).(14) The installation should be made to a vertical piping system in the following cases:a) Bubbles may remain in the piping.b) The distribution of density in the piping may become uneven because the material to bemeasured precipitates or floats unusually due to slow flow rate etc.c) When main piping is enlarged and the density meter is installed to a larger piping system than themain piping.(15) We recommend that the converter section stay at the top when the density meter is installed to ahorizontal piping system because the maintenance is easy and its performance is assured.(16) We recommend that the density meter should be installed at a point as far away as possible from a portopen to atmosphere and the water pressure is required a little to prevent bubbles from entering in thefluid to be measured.[NOTE]](https://usermanual.wiki/Toshiba/62372311/User-Guide-231580-Page-23.png)
![ 22 6 F 8 A 0 7 8 7(17) On both the upstream and downstream sides of the density meter, install shutoff valves. Furthermore,between these valves and the density meter, install the sampling port, the zero water supply port, theair release port, the drain port with a shutoff valve attached respectively. In the event that the flow of thepipe line cannot be stopped, provide a bypass pipe halfway with a shutoff valve attached. Whenperforming zero point calibration, these are needed to discharge the measured matter out of the densitymeter through its drain port and fill up the meter with fresh water of zero density. (See Figures 3.3.2 and3.3.3.)(18) As to insertion orientation, install the density meter so that a pair of antennas face toward upstream.<Precautions when installing the density meter in a tank>(19) In a tank, install the density meter so that the applicators (antenna) are submerged 150 mm or moreunder water from the surface. If the depth of water is less than 150 mm or the applicators surface staysabove the water level in cases like a pump operation, use the external synch signal and measure thedensity only when the applicators surface remains more than 150 mm under water (see Figure 3.3.1.)(20) Install the density meter far from such places as near the agitator in a tank where bubble are generatedand density disturbances occur and this affects the density measurement.[NOTE]♦ Sampling valve: Used to extract fluids for manual analysis. Install this valve to the side of thepipe in the case of horizontal installation. It is recommended that a 1-inchball valve be installed to the side of the pipe.♦ Zero point water valve: Used to supply drinking water (density or consistency 0%) to the detectorpipe for zero point adjustment. Install this valve at the top of the pipe in thecase of horizontal installation. It is recommended that a 1-inch ball valve beinstalled in the top of the pipe and zero point water is supplied through thisinlet using a vinyl hose etc.If valve water pipe is connected to this valve, air cannot be extracted.Therefore, another valve (vent valve) is needed to extract air.♦ Vent valve: Used to vent process fluids to open air when performing zero adjustment.This helps the drinking water (density or consistency 0%) enter the detectorpipe easily. Install this valve in the top of the pipe in the case of horizontalinstallation.♦ Drain valve: Used to drain the fluids before supplying drinking water (density orconsistency 0%) to the detector pipe for zero adjustment. Install this valve atthe lowest point of the pipe. It is recommended that a 1-inch ball valve beinstalled at the lowest point of the pipe.Metal tank1500mm or more120mm or lessWater surfaceFluid to be measuredFigure 3.3.1 Precautions when installing the density meter in a tank](https://usermanual.wiki/Toshiba/62372311/User-Guide-231580-Page-24.png)

 Provide a switch and a fuse to separate this unit from the mains power for ease of maintenance.Power requirement of this unit is 50VA.(2) Ground the LQ300A00****** with 100 Ohms or less ground resistance. Do not use a common groundshared by other power equipment. The demands of the meter are 50VAs.(3) Use a sheathed cable (CVV) with 2mm2 cross-sectional area for AC power cable and make sure thevoltage drop across the cable is less than 2 V. And use a M4 sized solderless contact for connectioncable with terminal.(4) The cables should be free from vibration or sway. The cables should be placed in thick-walled steelconduits.(5) Wire the LQ300A00****** output in conduit separated from those of AC power cable, control signals,alarm signal or other cables which could become the source of noise.(6) Use a 2-wire shielded sheathed cable (CVVS) to wire the LQ300A00****** output (4 - 20mAdc). Andground the shielded cable on the receiving instrument side. For performing the conductivitycompensation, use a 2-wire shielded sheathed cable (CVVS) to wire the LQ300A00****** conductivitysignal input (4-20mA). And ground the shielded cable on the receiving instrument side.(7) As the cable port is made air-tight using a packing, tighten the cable gland securely when all thewiring is completed. If the diameter of the cable is smaller than the inside diameter of the packing,enlarge the cable diameter to the same size as the packing by wrapping valves around the cable. Itssuitable diameter is 11mm.(8) Tighten the terminal screws securely. Appropriated torque to tighten the screws is 1.2 N･m .(9) Do not turn on the power of the density meter when the applicators (antenna) are taken out of thepiping system. Leakage of radio waves may cause interference to external equipment.](https://usermanual.wiki/Toshiba/62372311/User-Guide-231580-Page-28.png)

![ 59 6 F 8 A 0 7 8 76.3.2 Verifying and setting measurement conditions(1) Verifications and settings for initial powering-ONIn the event of starting the operation after turning on the power for the first time since installingthis density meter, it is necessary to first set the measurement conditions of the converter. Variousmeasurement conditions (parameters) are verified and set by means of the setting key whileviewing each menu screen of the LCD indicator. Major measurement conditions are as follows.1) Verifying and setting the measurement range.Unless otherwise specified in your order, the value here is set to 0 to 3%TS, which is theprovisional set value at the time of factory shipment. Reset the value in accordance with theoperation condition of your plant. If the measurement range is specified in your order, verifythat the value is set as specified. If the value is different, reset it.2) Verifying and setting the operation modeAt the time of factory shipment, this is set to "CONT" (the normal continuous operationmode). In the event of the density meter being made empty due to pump shutdown or valveclosure, etc. or of using such a method that stops the flow for some time, it is recommendedthat "EXT" (the external synchronized operation of switching between ON/OFF ofmeasurement by means of ON/OFF of the external contact input signal connected with thepump ON/OFF) be selected.In the event that the external synchronized operation is selected, the values of “delayed time(dt)” and “output at contact OFF(ho)” are the provisional set values at the factory shipment.If the those values are meet to the operation conditions of the plant rest it to an appropriatevalue in accordance with the operation conditions of the plant.3) Verifying and setting the simulated output in setting mode. Normal measurements aresuspended while this density meter is in the setting mode (see “2 SETTING MENU”); thus,both the density display and the density output are given the simulated values ( density testoutput (ot)) that are set beforehand. Although, at the time of factory shipment, the value isprovisionally set to "1.5%TS" (50% of the specified full-scale density if the measurementrange is specified), reset it to an appropriate value in accordance with the operationconditions of the plant.4) Verifying and setting the moving average timesAt the time of factory shipment, the "moving average times" is set to 1 (without the movingaverage). If the averaged output is required to be used for density control, etc., set it to about10. The more the moving average times, the worse the responsiveness becomes with regardto density variation. Therefore, set it to an appropriate value in accordance with the plantconditions, including the right balance with the responsiveness.5) For other measurement conditions, the standard values are set. Therefore, it is normallyunnecessary to change these settings."10 VARIOUS FUNCTION" describes various functions of the Density Meter LQ300A00******. If necessary,make additional settings for using these functions appropriately.(2) Verifications at the time of normal power-ONIn the event that measurement conditions of the converter are already set with the operation notbeing the first one since installation, verify the set value while referring to (1).[NOTE]](https://usermanual.wiki/Toshiba/62372311/User-Guide-231580-Page-61.png)

Youdo not need to calibrate the meter for zero point before using it at site.In the case of the density readings are found to be way off from the result by manual analysis, or whenyou need to read just the zero point for a particular reason, follow the procedures below in calibratingthe zero.For information on the converter operation and the LCD display regarding zero-point calibration, pleaserefer to Subsection 5.2.11.(1) Switching to the setting mode (see Subsection 5.2.5)First of all, press the [ESC] key of the converter several times (normally once although this varieswith the operation status) to return to the initial menu display. Next, use the [→] key to move theLCD indicator cursor to the menu number "2" of "2 SETTING MENU" and then press the [SET]key to display the warning message saying "Test output will be valid." Make sure that there is noproblem and then press [→] to get into the setting mode. To get into [2: SETTING MENU], it isnecessary to further enter the password "8000". Then, the output will be switched to thesimulated output that is set beforehand.(2) Stop the flow in or out from the tank and in the piping system.If it is possible to stop the flow in or out from the tank and in the piping system where the densitymeter is installed, do so by, for example, turning off the pump.●If it is not allowed to stop the fluid flow through the pipeline:When it is not permitted to stop the flow of the line, bypass the flow by opening the valve onthe bypass pipe.◆It is recommended that the bypass piping be installed for adjustment/maintenancepurposes such as zero calibration in the event that the flow in the pipe line cannot bestopped.(3) Close the upstream valve and downstream valveClose the shutoff valves on both sides of the detector tightly.Note: Be sure to close the upstream valve first.◆In the event that the density meter is installed on the discharge side of the pump, makesure to shut the valves starting from the upstream one to prevent the fluid pressure inthe density meter from rising.(4) Drain the detector pipeOpen the drain valve on the pipeline to discharge the fluid from the main pipe of the detector.(5) Open the zero water feed portOpen the valve or remove the cap to feed zero water.◆Make sure that the pressure of the fluid in the detector gets low enough to let the valveopen without causing blow out of the fluid. Any remaining pressure will cause themeasured matter to be spurted out. Be careful about this.(6) Close the drain valve](https://usermanual.wiki/Toshiba/62372311/User-Guide-231580-Page-62.png)

(It is not necessary to make the water clean and transparent.)(9) Fill the tank or the piping system where the density meter is installed.When cleaning is finished, close the drain valve and fill the tank or the piping system with zerowater. Keep adding water while releasing air until water overflows the supply port.(10) WaitLeave the detector and water in this state for about 5 minutes.◆In the event that the flow of the measured matter can be switched to that of the zero water byswitching over to another valve, etc., it is all right to replace the work activities (2) to (10)with the relevant method and implement the following zero calibration while allowing thezero water to keep flowing. Even when switching the flow to that of zero water, wait forabout 15 minutes before implementing the zero calibration.(11) Selecting the zero calibration menu (see Subsection 5.2.5)After verifying that the converter is in the setting mode ("2 SETTING MENU") through theoperation of (1), use the [→] key to move the cursor of the LCD indicator to the menu number "6"of [6 ZERO CALIBRATION] and then press the [SET] key.(12) Check zero water density reading (see Subsection 5.2.11)The measured density of zero water is displayed on the density indicator. If the indicator shows[-0.00], it means that the zero point is off toward the negative.◆In the Setting menu, LED density display indicates the preset Density Test output, but in theZero calibration menu, the LED density display indicates the density value measured at thesame time the calibration is executed so that it is possible to check the zero point before andafter the calibration.(13) Zero calibration (see Subsection 5.2.11)If the zero point is found to be off, press the [SET] key. The data (θ1, T0, A0, zG) of the zero pointis replaced by the current data, thus rendering the angle rotation to N=0 and automatically thedensity display to zero. The data (θ1, T0, A0, zG) of the zero point is stored in the memory of thedensity meter until the zero calibration is implemented once again, thus making it possible toverify it on the constant monitoring menu. However, for the purpose of history management, keepa note of the data.◆Unless the zero point is out of place, the zero calibration is suspended by pressing the [ESC]key.(14) End zero calibrationThis completes the zero calibration. Close the zero water valve, ensure that the sampling valveand drain valve are closed, then open the shutoff valves on both ends of the detector pipe,downstream first and upstream next. Lastly, close the shutoff valve on the bypass pipe to restorethe flow of the fluid as before the calibration.](https://usermanual.wiki/Toshiba/62372311/User-Guide-231580-Page-63.png)

![ 75 6 F 8 A 0 7 8 79.2 Various Kinds of Corrections9.2.1 Phase angle rotation correctionThe phase is available only from 0 degree to 360 degrees. If the phase incrementally reaches 360degrees, it returns to 0 degree, from which it keeps incrementing again. If the phase decreasinglyreaches 0 degrees, it returns to 360 degrees, from which it keeps decreasing again. Accordingly, theconcept of phase angle rotation is incorporated into this density meter and some corrections have beenmade so to allow the phase to change to an unlimited extent. In such a manner, this density meter hasovercome the limit that the phase is available only from 0 to 360 degrees, thus realizing high densitymeasurement.Phase angle rotation correction refers to obtaining the real phase angle θ2 by judging the number ofrotations the dummy angle θ2' belongs to based on the measured values coming before and after.θ2 = θ2' + N x 360 (degrees)N: Number of rotationsSet N=0 at the time of zero calibration, making the number of rotations to zero for the phase angleθ1 at zero point.If the θ2' exceeds 360 degrees to enter into the next rotation, set N=1. If it again exceeds 360degrees to enter into the rotation after the next rotation, set N=2.(N will move up to 2 only if the meter is of large diameter and the density is high.)On the other hand, if θ2' goes below zero (0) degree to enter into the previous rotation, decreaseN by one (1). In other words, when it goes into the -1st rotation from the 0th one, set N=−1; andwhen into the 0th rotation from the 1st one, set N=0.Note: The description above is the basics regarding the phase angle rotation correction. Normally, it isall right to use the density meter without being aware of this correction. However, in the event ofmeasuring high density, etc., special setups and actions may be needed. For details, refer toSection 9.3.9.2.2 Liquid temperature correctionThe phase tends to change in a straight line with regard to the liquid temperature.

Therefore, when the measured densityexceeds 21.17(%TS), the adjustment of decreasing the number of phase angle rotationsapplies as shown in Table 9.3.1, thus making it impossible to measure the density inexcess of 21.17(%TS).To solve the problems as shown in the example above, measurement is taken so that the function ofautomatic adjustment of phase angle rotations is automatically invalidated if the upper measureddensity range exceeds Xmax.Check the operating conditions to see if the function of automatic adjustment of phase angle rotations isapplicable or not.In the cases where the automatic adjustment of phase angle rotations is not applicable, after the tank or the pipingsystem (where the density meter is installed) is temporarily made empty, it is necessary to reset the phase anglerotation to an appropriate value through manual input. In the cases, it is more desirable to perform the externalsynchronized operation.9.3.6 Invalidation by setting the automatic adjustment of phase angle rotationsAs mentioned in the previous subsection, the density meter is equipped with the function ofautomatically invalidating the function of automatic adjustment of phase angle rotations, based on theconditions for setting the upper density measurement range and the density multiplier. However, in thestate of starting the operation, the upper density measurement range is determined but the densitymultiplier is not determined yet (determined in the span calibration described in Section 6.5), thus theoperation is started with a provisional value (initial value: 1). Therefore, the function of automatic[NOTE]](https://usermanual.wiki/Toshiba/62372311/User-Guide-231580-Page-80.png)
![ 79 6 F 8 A 0 7 8 7adjustment of phase angle rotations, which is supposed to be invalidated, may not be invalidated,making it impossible to take an appropriate measurement (including the span calibration). This appliesto the case in which the original density multiplier is smaller than the current set value (the initial value1 in the initial operation).There are two ways of dealing with such a case.One is to automatically invalidate the function of automatic adjustment of phase angle rotations byprovisionally setting a sufficiently small value such as about 0.5 for the density multiplier C so thatXmax is smaller than the upper density measurement range.Another is to forcibly invalidate the function of automatic adjustment of phase angle rotations. Thelatter's setting method is described below.(1) Switching to the setting mode (see Subsection 5.2.5)First of all, press the [ESC] key of the converter several times (normally once although this varieswith the operation status) to return to the initial menu display. Next, use the [→] key to move theLCD indicator cursor to the menu number "2" of "2 SETTING MENU" and then press the [SET]key to display the warning message saying "Test output will be valid."

Then, the output will be switched to thesimulated output that is set beforehand.(2) Selecting the "OTHERS" setting menu (see Subsection 5.2.5)Initially, the menu list of menu numbers 5 to 8 is displayed. However, by pressing the [UP] keyonce, this display can be switched to the menu list of the next menu numbers 9 to 11. Use the [→]key to move the LCD indicator cursor to the menu number "11" of "11: OTHERS" and then pressthe [SET] key to select the menu of "11: OTHERS."(3) Verifying or changing ON/OFF of automatic adjustment of phase angle rotations(See Subsection 5.2.16)Press the [DN] key once (or the [UP] key five times) to display "NA: N AUTO ADJUSTMENT".On this screen, it is possible to verify whether the automatic adjustment of phase angle rotationsis valid (ON) or invalid (OFF). Here, if it is necessary to alter the setting, press the [SET] key toswitch to the setup display of the automatic adjustment of phase angle rotations. Each time the[UP] or [DN] key is pressed, the set value is alternated between ON and OFF. Set the value toOFF and then press the [SET] key to confirm it. The screen will be returned to the immediatelypreceding one; make sure that the value is correctly reset.(4) Returning to the measuring mode Press the [ESC] key twice to return to the initial menu screen and return to the measuring modefrom the setting mode to resume the normal measurement.9.3.7 Actions after invalidating the automatic adjustment of phase angle rotationsAfter invalidating the automatic adjustment of phase angle rotations to make it possible to takemeasurements appropriately even at high density in excess of Xmax, implement the span calibration inaccordance with Section 6.5 and set the density multiplier to an appropriate value. While referring toTable 9.3.2, use this reset density multiplier to calculate the maximum density Xmax, which can beapplied to the function of automatic adjustment of phase angle rotations and judge whether this Xmax isgreater than the value of the upper density measurement range that is set.](https://usermanual.wiki/Toshiba/62372311/User-Guide-231580-Page-81.png)
![ 80 6 F 8 A 0 7 8 7If Xmax is greater than the upper density measurement range, the function of automatic adjustment ofphase angle rotations is applicable. Therefore, return the function of automatic adjustment of phaseangle rotations which is set to "OFF" in Subsection 9.3.6 to“ON”.If Xmax is smaller than the upper density measurement range, the function of automatic adjustment ofphase angle rotations is invalid. Therefore, it is unnecessary to return the function of automaticadjustment of phase angle rotations which is set to "OFF" in Subsection 9.3.6 to “ON”.9.3.8 Return to the normal through manual input of the phase angle rotationsIf the function of automatic adjustment of phase angle rotations is not applicable whereas the pipingsystem (where the density meter is installed) is temporarily made empty thus causing the number ofphase angle rotations to jump to a faulty number, the number of phase angle rotations fails to return toan appropriate value even when the piping system (where the density meter is installed) is refilled withthe matter to be measured, thus allowing the measured density to remain in error. In this connection, it isnecessary to reset the phase angle rotation to an appropriate value through manual input.
