General information 2.1.3 Confined space precautions DANGER Explosion hazard. Training in pre-entry testing, ventilation, entry procedures, evacuation/rescue procedures and safety work practices is necessary before entering confined spaces. Important Note: The following information is provided to guide users of Flo-Dar and SVS Sensors on the dangers and risks associated with entry into confined spaces. On April 15, 1993, OSHA’s final ruling on CFR 1910.146, Permit Required Confined Spaces, became law. This new standard directly affects more than 250,000 industrial sites in the U.S.A., and was created to protect the health and safety of workers in confined spaces. Definition of a confined space: A confined space is any location or enclosure that presents or has the immediate potential to present one or more of the following conditions: • An atmosphere with less than 19.5% or greater than 23.5% oxygen and/or more than 10 ppm Hydrogen Sulfide (H2S). • An atmosphere that may be flammable or explosive due to gases, vapors, mists, dusts or fibers. • Toxic materials which upon contact or inhalation, could result in injury, impairment of health or death. Confined spaces are not designed for human occupancy. They have restricted entry and contain known or potential hazards. Examples of confined spaces include manholes, stacks, pipes, vats, switch vaults, and other similar locations. Standard safety procedures must always be followed prior to entry into confined spaces and/or locations where hazardous gases, vapors, mists, dusts or fibers may be present. Before entering any confined space check with your employer for procedures related to confined space entry. 2.1.4 FCC Regulations This device complies with Part 15C, Subpart 245 of the FCC Rules and Industry Canada RSS210. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that causes undesired operation. No additional user license is required. Any changes or modifications not expressly approved by Marsh-McBirney. could void the users authority to operate the equipment. General information 2.2 Product overview The Flo-Dar Sensor measures the flow velocity and liquid depth in open channels using radar and ultrasonic technology. The unit is designed to withstand submersion during surcharge conditions. The optional surcharge velocity sensor provides velocity measurements during surcharge conditions. Figure 1 shows the configuration of a Flo-Dar system in a non-hazardous location. Figure 1 System overview Flo-Dar sensor with optional surcharge velocity sensor Mounting frame Logger or controller Non-hazardous environment 2.2.1 Theory of operation The Flo-Dar Sensor is mounted above an open channel of water and measures the surface velocity and depth from above the surface of the water. The two measurements are used to calculate the flow rate. During surcharge (submerged) conditions, a pressure transducer measures depth. The optional surcharge velocity sensor (SVS) can be used to measure velocity during surcharge conditions. Surface velocity measurement The surface velocity of the water is measured using radar technology. A radar beam is transmitted from the sensor to the water surface at the center of the channel. A portion of the signal is reflected back at a slightly different frequency. The difference in frequency, known as the Doppler frequency, is directly proportional to the speed of the flow. Proprietary algorithms are then used to calculate the average speed of the flow stream. Note: The radar velocity sensor does not operate under surcharge conditions. Velocity measurements during surcharge The optional surcharge velocity sensor (SVS) is activated when the flow level rises to within four inches of the depth sensor and remains active until the flow falls to four inches below the sensor. The SVS measures velocity using an electromagnetic sensor that generates a magnetic field. When the water passes through the magnetic field, a voltage is generated that is directly proportional to the speed of the water passing the sensor. General information Depth measurement The water depth is measured using an ultrasonic pulse echo sensor. An electronic pulse is sent to the water surface and a portion of the signal is returned to the sensor. The transit time to the surface and back is used to calculate the distance from the water surface to the sensor. The pipe diameter is used to convert the distance to water depth. The depth sensor on the Flo-Dar unit can measure distances up to 1.5 m (5 ft). For larger channels, an extended range sensor is available to measure up to 5.7 m (18.7 ft). During surcharge conditions, a pressure transducer in the Flo-Dar unit is used to measure depth. Flow calculations The velocity and depth measurements are used with the pipe diameter to determine the flow rate. The flow rate is calculated from the continuity equation (1): (1) Flow rate = Average velocity u Area where Flow rate = volume of liquid that passes the sensor per unit time (e.g. 200 gallons per minute) Average velocity = average velocity of the liquid, calculated using surface velocity measurements and algorithms Area = cross-sectional area of the liquid in the channel, calculated using the channel dimensions and depth measurement. 10 Section 3 Installation DANGER: Potential Explosion Hazard Only qualified personnel can do the tasks given in this section of the manual. The Flo-Dar Sensor can only be installed in non-hazardous environments. CAUTION: Radar RF Exposure Hazard Although the Flo-Dar microwave power level is very small (~15mW) and is well below government stated exposure limits for uncontrolled environments, users of this product should follow proper safety protocols for the handling of devices with radar frequency transmitters. Avoid placing the head and other vital organ areas within the microwave beam (within 1 meter of the microwave aperture). 3.1 Component list Important Note: Delicate Instrumentation. Handle with care to prevent damage to the microwave transmitter. Damaged transmitters can result in higher signal power levels, which can interfere with essential terrestrial microwave links. Make sure that the instrument components shown in Figure 2 have been received. 11 Installation Figure 2 Instrument components Surcharge velocity sensor (SVS) (optional) 10 Clamp bolt, ¼–20 x 1 in.

An ideal location is in a long, straight channel or pipe. Outfalls, vertical drops, baffles, curves or junctions cause the velocity profile to become distorted. Where there are outfalls, vertical drops, baffles, curves or junctions, install the sensor upstream or downstream as shown in Figure 3 and Figure 4. For upstream locations, install the sensor at a distance that is at least five times the pipe diameter or maximum fluid level. For downstream locations, install the sensor at a distance that is at least ten times the pipe diameter or maximum fluid level. If the location contains a junction and the flow in one pipe is much higher, install the sensor on the wall near the lower flow pipe. Figure 3 Sensor location near an outfall, vertical drop or baffle Acceptable upstream sensor location Distance downstream: 10 x pipe diameter Outfall Vertical drop Distance upstream: 5 x pipe diameter Baffle Acceptable downstream sensor location 13 Installation Figure 4 Sensor location near a curve, elbow or junction Acceptable upstream sensor location Distance downstream: 10 x pipe diameter Acceptable downstream sensor location Distance upstream: 5 x pipe diameter 14 Installation 3.2.2 Sensor installation Mount the Flo-Dar sensor above the open channel on the wall of the manhole. A pole is available for retrieval of the Flo-Dar sensor without entry into the manhole. For temporary installation, an optional Jack-bar is available (see Accessories on page 33). Instructions are included with the Jack-bar. The Flo-Dar sensor dimensions are shown in Figure 5 and Figure 6.

Prerequisites • Frame • Wall mount bracket • Clamps • Hardware—wall bracket, spacer, nuts and bolts Procedure 1. Position two clamp halves (one with threads and one without threads) around the wall mount bracket as shown in Figure 8. 2. Connect the clamp halves together with four bolts. Lightly tighten the bolts to temporarily hold the clamp in position. 17 Installation 3. Position the other two clamp halves around the front end of the frame as shown in Figure 8. Note: In most cases the front of the frame will point toward the wall as shown in Figure 8 (see also Figure 12 on page 23). If flow conditions require the sensor to point away from the wall, use the 12 inch spacer and position the two clamp halves around the back end of the frame. 4. Connect the clamp halves together with four bolts. Lightly tighten the bolts to temporarily hold the clamp in position. Figure 8 Clamps assembled on wall bracket and frame Adjustable wall bracket Frame Clamp half, threaded Spacer Clamp bolt, ¼–20 x 1 in. Wall mount bracket Clamp half, not threaded 18 Installation 3.2.2.2 Install the frame on the wall DANGER Explosion hazard. Review the safety information in section 2.1.3 on page 8 before entering a confined space. Sensor location guidelines Review the following guidelines to find the best location for the sensor. • Examine the upstream and downstream flow characteristics. Use a mirror if necessary. Install the sensor above the water where the flow is steady. Do not install the sensor where there are standing waves, pools or objects or materials that can disrupt the flow profile. • If the upstream flow characteristics are acceptable, install the sensor on the upstream wall of the manhole with the sensor pointing upstream. This location will make sure that the measured flow is the same as the flow in the pipe and that the sensor cable points away from the wall. • Install the sensor away from the sides of the pipe and in the very center of the flow where the fluid is at the maximum depth. • Install the sensor in a location that is accessible for maintenance. Prerequisites • Frame and wall mount bracket assembly (assembled in section 3.2.2.1) • Anchors with nuts and washers • Drill • 3/8-inch • Tools: mirror, ruler or tape measure, marker concrete drill bit with tape to indicate a depth of 1½ inches Procedure Complete the steps to install the frame on the wall of the manhole above the flow. 1. Make a mark on the wall that identifies the location of the top of the sensor frame (Figure 9). The wall brackets will be installed above and below this mark. • Flo-Dar without SVS—make sure that when the sensor is in the frame, the radar beam will not be blocked by the wall or channel (Figure 11). • Flo-Dar with SVS—the top of the sensor frame must be installed at an exact distance above the top of the channel. For pipe diameters greater than 24 inches, measure 5 inches from the top of the channel to the top of the frame. For pipe diameters less than 24 inches, measure 6 inches from the top of the channel to the top of the frame. 2. Position the wall mount brackets above and below this mark. 3. Make two marks to identify the position of the holes for each bracket. 4. Use a 3/8-inch drill bit to drill two holes at a depth of 1½ inches. Remove the debris from the holes. 5. Put the anchors in the holes and tap lightly with a hammer to seat the anchors. 6. Position the brackets over the holes and install the washers and nuts. Hold the brackets and tighten the nuts on the anchors. Do not over-torque. 7. Connect the frame to the wall bracket with a spacer as shown in Figure 9. The 12-inch spacer may be necessary to position the sensor farther from the wall when there is a large pipe lip. 19 Installation Figure 9 Wall installation Distance from crown of pipe to top of frame Washer Anchor Nut 3.2.2.3 Install the sensor on the frame The sensor fits in the frame in only one direction and locks in position when the bail on the sensor is turned (Figure 10). The sensor can be removed from the frame and installed without entering the manhole when the optional retrieval pole is used (see Accessories on page 33). Procedure 1. Make sure that the cable is tightly connected to the sensor. 2. Turn the bail to retract the locking bars on the sensor. 3. Position the sensor on the frame. The cable should point toward the center of the manhole. 4. Turn the bail to lock the sensor on the frame (Figure 10). 20 Installation Figure 10 Horizontal alignment Bubble level Bail 3.2.2.4 Align the sensor vertically—Flo-Dar without SVS The sensor must be aligned vertically to make sure that the sensor is above the flow and that the radar beam will not be blocked by the wall or pipe (Figure 11). Use the optional laser alignment tool for best accuracy (see Accessories on page 33). Procedure 1. Make an estimate of where a line that extends from the top of the radar lens perpendicular to where the lens will point (Figure 11). Use the laser alignment tool for best accuracy. 2. Loosen the clamp on the wall mount bracket and position the frame so that the radar beam will point below the crown of the pipe by at least 1 inch (Figure 11). It may be necessary to install the 12 inch spacer to extend the frame farther from the wall. 3. Tighten the clamp and measure the frame position. Make sure that the radar beam is not blocked by the wall or pipe. If the beam is blocked, move the frame further away from the wall using the 12 inch spacer or lower the frame. 21 Installation Figure 11 Vertical alignment of Flo-Dar sensor Spacer Distance from crown of pipe to top of frame 3.2.2.5 Align the sensor vertically—Flo-Dar with SVS The sensor must be aligned vertically to make sure that the sensor is above the flow under normal full flow conditions and that the SVS is activated under surcharge conditions. Prerequisites • Ruler or tape measure Procedure 1. Measure directly above the crown of the pipe to the top of the frame (Figure 9 on page 20). 2. If the pipe lip is longer than 5½ inches, install the 12 inch spacer between the wall mount bracket and the frame (Figure 12). 3. Loosen the clamp on the wall mount bracket and position the top of the frame above the crown of the pipe at the specified distance: 22 • 6 inches for a pipe diameter that is less than 24 inches • 5 inches for a pipe diameter that is equal to or larger than 24 inches Installation 4. Tighten the clamp and measure the frame position again to make sure it is at the correct position. Figure 12 Vertical alignment of Flo-Dar sensor with SVS Spacer Distance from crown of pipe to top of frame SVS sensor (optional) 3.2.2.6 Align the sensor horizontally The sensor must be aligned horizontally to make sure that the sensor is centered over the flow. If the pipe is not level and has a slope of 2 degrees or more, align the sensor to be parallel with the surface of the water. Prerequisites • Bubble level Procedure 1. Remove the paper backing from the bubble level and attach the level to the sensor (Figure 10 on page 21). 2. Loosen the clamps and tap the frame into position. 3. Tighten both clamps and measure the frame position to make sure it is at the correct position. 23 Installation 3.2.2.7 Make a final alignment check The correct vertical and horizontal alignment of the sensor is necessary for accurate measurements. 1. Measure the vertical alignment (section 3.2.2.4 on page 21 or section 3.2.2.5 on page 22) and make adjustments if necessary. 2. Measure the horizontal alignment (section 3.2.2.6 on page 23) and make adjustments if necessary. 3. Repeat steps 1 and 2 until no further adjustments are necessary. 3.2.2.8 Optional extended depth sensor installation The extended depth sensor (Figure 13) can be used when the pipe or channel depth exceeds the standard level specifications (see Specifications on page 5). Use the extended frame (Figure 14) in place of the standard frame, or mount the extended depth sensor on the wall. Unlike the standard frame, the extended frame is reversible with regard to mounting direction. The extended depth sensor has a deadband zone below the sensor of 16 inches where the sensor is not active. Install the extended depth sensor at least 16 inches above the crown of the pipe for correct measurements. Figure 13 Extended sensor dimensions 24 Installation Figure 14 Extended frame dimensions 29.1 in. with 2¼ in. spacer; 38.8 in. with 12 in. spacer Figure 15 Vertical alignment with extended depth sensor Spacer 25 Installation 3.2.3 Measure the sensor offset The sensor offset is the distance from the top of the frame to the bottom of the pipe or channel. This distance will be entered into the software and is necessary for accurate flow calculations. If the extended depth sensor (section 3.2.2.8 on page 24) is installed on the wall without the extended frame, the sensor offset is the distance from the face of the extended depth sensor to the bottom of the pipe or channel. Prerequisites • Rod • Tape measure Procedure 1. Put the rod in the bottom of the pipe or channel and align it vertically with the frame (Figure 16). 2. Make a mark on the rod to identify where the top of the sensor frame is. 3. Measure the distance from the bottom of the rod to the mark. This is the sensor offset. Note: If it is not practical to measure to the bottom of the pipe, measure the distance from the crown of the pipe to the top of the frame (Figure 16). Add this distance to the pipe diameter to get the sensor offset (sensor offset = pipe diameter + distance from crown of the pipe to top of frame). Figure 16 Sensor offset Distance from crown of pipe to top of frame Pipe diameter 26 Sensor offset Installation 3.2.4 Measure the pipe diameter The correct diameter of the pipe or channel is necessary for accurate flow calculations. 1. Measure the inside pipe diameter (I.D.) at three locations (Figure 17). Be sure that the measurements are accurate. 2. Calculate the average of the three measurements. Record this number for use during the software setup for the site. Figure 17 Pipe diameter measurement 3.3 Electrical installation 3.3.1 Wiring safety information When making any wiring connections to the instrument, the following warnings and notes must be adhered to, as well as any warnings and notes found throughout the individual installation sections. For more safety information refer to section 2.1 on page 7. CAUTION Possible danger to sensor or logger. Always disconnect power to the instrument when making any electrical connections. CAUTION: Radar RF Exposure Hazard Although the Flo-Dar microwave power level is very small (~15mW) and is well below government stated exposure limits for uncontrolled environments, users of this product should follow proper safety protocols for the handling of devices with radar frequency transmitters. Avoid placing the head and other vital organ areas within the microwave beam (within 1 meter of the microwave aperture). 3.3.1.1 Electrostatic Discharge (ESD) considerations Important Note: To minimize hazards and ESD risks, maintenance procedures not requiring power to the instrument should be performed with power removed. Delicate internal electronic components can be damaged by static electricity, resulting in degraded instrument performance or eventual failure. 27 Installation The manufacturer recommends taking the following steps to prevent ESD damage to your instrument: • Before touching any instrument electronic components (such as printed circuit cards and the components on them) discharge static electricity from your body. This can be accomplished by touching an earth-grounded metal surface such as the chassis of an instrument, or a metal conduit or pipe. • To reduce static build-up, avoid excessive movement. Transport static-sensitive components in anti-static containers or packaging. • To discharge static electricity from your body and keep it discharged, wear a wrist strap connected by a wire to earth ground. • Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and work bench pads. 3.3.2 Connection to the logger or controller Connect the cable from the Flo-Dar sensor to the logger or the controller: 28 • Logger—connect the cable from the Flo-Dar sensor to the Flo-Dar connector on the logger. If the Flo-Dar sensor has the SVS component, connect the cable from the SVS component to the SVS connector on the logger. • Controller—connect the cable from the Flo-Dar sensor to the correct terminal in the controller. If the Flo-Dar sensor has the SVS component, connect the cable from the SVS component to the correct terminal in the controller. Refer to the user manual for the controller for the correct terminal locations. Section 4 Operation A portable computer with Flo-Ware software must be connected to the controller or logger to set up and collect data from the Flo-Dar sensor. 4.1 Install the Flo-Ware software on the PC Procedure 1.

When using the retrieval pole, make sure to connect the grounding strap to the ground lug of the barrier with the sensor cable (at least the shields) terminated to the barrier. This is to prevent ignition of explosive gases due to static discharge. The safety of the transmitter may be impaired if any of the following conditions have occurred: • visible damage • storage above 70ºC for prolonged periods • exposure to severe transport stresses • previous installation • failure to operate properly If any of these conditions have occurred, return the device to the manufacturer for recertification. CAUTION: Radar RF Exposure Hazard Although the Flo-Dar microwave power level is very small (~15mW) and is well below government stated exposure limits for uncontrolled environments, users of this product should follow proper safety protocols for the handling of devices with radar frequency transmitters. Avoid placing the head and other vital organ areas within the microwave beam (within 1 meter of the microwave aperture). Important Note: Delicate Instrumentation. Handle with care to prevent damage to the microwave transmitter. Damaged transmitters can result in higher signal power levels, which can interfere with essential terrestrial microwave links. 5.1 Preventive maintenance Examine the Flo-Dar sensor on an annual basis to look for corrosion or damage that can allow environmental gases into the interior. Make sure that no swelling, blistering, pitting or loss of material has occurred on the upper and lower portions of the main plastic enclosure, the depth module or the radome. If the extended depth sensor is used, examine the enclosure and the four ¼-20 SS bolts. If the surcharge velocity sensor (SVS) is used, make sure the unit is not corroded and the labels are readable. Inspect the cable connectors for any damage or corrosion and tighten all connectors in the system. The only parts of the Flo-Dar system that can be replaced by the user are the bail assembly, cable and desiccant. If the sensor becomes defective, it must be replaced as a complete unit. Check the electrical connections Examine the cable connectors on an annual basis for corrosion and tightness. If corrosion is found, clean and dry the connectors to make sure that no moisture is on the connector pins. If corrosion is severe, replace the cables. 5.2 Cleaning the instrument Regular cleaning is not necessary because the sensor does not contact the flow unless a surcharge condition occurs. Examine the sensor after a surcharge to see if cleaning is necessary. Prerequisites • Retrieval pole with hook (optional, see Accessories on page 33) 31 Maintenance Procedure: 1. Remove power to the sensor. 2. Put the hook on the retrieval pole for removal without manhole entry. Make sure the grounding strap is on the pole. 3. Hook the bail on the sensor and turn the pole counter-clockwise to unlock the sensor from the frame. Remove the sensor. 4. Remove any debris from the bottom of the sensor. Clean the external surface of the sensor with mild soap and rinse with water. DANGER Explosion hazard. Never attempt to wipe or clean the Flo-Dar or SVS sensor while in a hazardous location. Do not use abrasives or high-pressure hoses or washers to clean the sensors. Do not disturb the pressure port on the bottom of the sensor. 5. If the Surcharge Velocity Sensor (SVS) is used, use 600 grit sand paper to lightly sand the electrodes (small black dots). Use only light pressure when sanding or the electrodes will become damaged. 6. Lower and position the sensor on the frame. Make sure that the cable points toward the center of the manhole. 7. Turn the retrieval pole clockwise to engage the locking bars into the frame. 8. Apply power to the sensor. 5.3 Cable replacement Replace the cable only when it is damaged. Procedure 1. Remove power to the sensor. 2. Put the hook on the retrieval pole for removal without manhole entry. Make sure the grounding strap is on the pole. 3. Hook the bail on the sensor and turn the pole counter-clockwise to unlock the sensor from the frame. Remove the sensor. 4. Remove the cable clamp by removing the two Phillips screws on the sensor handle. Remove the cable. 5. Install the new cable. Make sure that the connector is aligned properly and that no debris or water gets into the connector. 6. Replace the cable clamp. 7. Lower and position the sensor on the frame. Make sure that the cable points toward the center of the manhole. 8. Turn the retrieval pole clockwise to engage the locking bars into the frame. 9. Apply power to the sensor. 32 Section 6 Replacement Parts and Accessories 6.1 Replacement Parts Description Catalog Number Bail assembly 800014901 Cable assembly, 30 ft, connector on one end 570011801 Cable assembly, 60 ft, connector on one end 570011804 Cable assembly, 100 ft, connector on one end 570011802 Cable assembly, 30 ft, connectors on both ends 131012601 Cable assembly, 60 ft, connectors on both ends 131012611 Cable assembly, 100 ft, connectors on both ends 131012602 Flo-Dar sensor 890004901 SVS Surcharge Velocity Sensor, replacement only 890006001 Wall mount assembly, standard frame (includes frame and hardware) 800016701 Wall mount assembly, extended frame (includes frame and hardware) 800016201 Wall mount hardware 800015401 6.2 Accessories Description Catalog Number Laser alignment tool 800012402 Hook for sensor retrieval pole 510012701 Sensor retrieval pole, 8–24 ft 245000501 Temporary mount assembly, standard frame, 34 in. to 52 in. manhole 800016401 Temporary mount assembly, standard frame, 52 in. to 70 in. manhole 800016402 Temporary mount assembly, standard frame, 70 in. to 88 in. manhole 800016403 Temporary mount assembly, standard frame, 89 in. to 107 in. manhole 800016404 Temporary mount assembly, extended frame, 34 in. to 52 in. manhole 800016301 Temporary mount assembly, extended frame, 52 in. to 70 in. manhole 800016302 Temporary mount assembly, extended frame, 70 in. to 88 in. manhole 800016303 Temporary mount assembly, extended frame, 89 in. to 107 in. manhole 800016304 33 Replacement Parts and Accessories 34 Section 7 How to order U.S.A. customers By telephone: 8:00 a.m. to 5:00 p.m. EST Monday through Friday Toll free:1-800 -368-2723 Local:1-301-874-5599 By fax: 1-301- 874-8459 By mail: McBirney-Hach Company Marsh McBirney Hach Comp 4539 Metropolitan Court Frederick, MD 21704-9452, U.S.A. sales@marsh-mcbirney.com Ordering information by email: em Ordering informa information ation ffor or outside the USA Marsh-McBirney Ma arsh-McBirney maintains a worldwide network of manufacturer's representatives. re ep prre es sentatives.
