An areaNclocity sensor shall be used to measure flow rate. A battery module shall provide power to operate the flow module. It shall be possible to stack and/ or interconnect multiple flow modules in the field for simultaneous monitoring of multiple flow streams and/ or for obtaining redundant measurements. 2) Area Velocity Sensor A) The sensor shall directly measure average liquid velocity using the ultrasonic Doppler method. The sensor shall not require a multiplying factor based on flow depth to convert a point velocity to the average liquid velocity. The sensor shall not require velocity profiling and calibration at the measurement site. The sensor shall not contain electrical contacts exposed to the liquid to measure velocity. The sensor shall contain an automatic gain control amplifier that shall automatically adjust its gain based on the strength of the received Doppler signal. i) The Doppler velocity measurement frequency shall be 500 kHz with a transmission angle of 20 degrees. The velocity measurement range of the sensor shall be from -5 to +20 feet per second ( -1. 5 to + 6. 1 meters per second). The velocity in water with a uniform velocity profile and a speed of sound of 4, 850 feet per second ( 1, 480 meters per second) shall be measured with a maximum error of t0. 1 feet per second (10.03 meters per second) over a range of -5 to + 5 feet per second ( -1. 5 to + 1. 5 meters per second), and t2% ofreading over a range of 5 to 20 feet per second ( 1. 5 to 6. 1 meters per second). The typical minimum depth for velocity measurement shall be 0. 08 feet ( 0.025 m). B) The sensor shall contain a differential integrated circuit pressure transducer to measure the hydrostatic pressure of the liquid to determine the liquid depth. i) The level measurement range of the sensor shall be from 0. 033 to 10.0 feet 0. 010 to 3. 05 m). The level shall be measured with a maximum error of+ 0. 008 feet per foot (10.008 in per m) over a range of 0.033 to 5. 0 feet ( 0. 010 to 1. 52 m), and t 0. 012 feet per foot (t 0.0012 in per m) for levels greater than 5. 0 feet ( 1. 52 m). The temperature coefficient shall be t 0. 0035 feet per degree F (t 0. 0019 in per degree C) over the compensated temperature range of 320 to 122° F ( 00 to 50° C).

The sensor shall not contain potentiometers to calibrate the pressure transducer. It shall not be necessary to recalibram the flow module, other than programming the current flow stream level, if the sensor is interchanged with another sensor. The analog output of the pressure transducer shall be converted to a digital value in the sensor, and the sensor shall transmit to the flow module a digital signal corresponding to the current level measurement. The sensor shall not transmit to the flow module an analog signal corresponding to the current level measurement. The flow module shall store the date and time that the level measurement was last adjusted. C) The sensor shall be 0. 75 inches ( 1. 9 cm) in height and 1. 31 inches ( 3. 3 cm) in width. ([ The sensor cable shall be 25 feet ( 7.62 m) long.) [ The sensor cable shall be _ long.l) r The cable shall terminate in a push -on, quick -connect connector so that the sensor can be easily removed and replaced in the field. The connect cable for the sensor shall include a vent tube that shall reference one side of the pressure transducer to atmospheric pressure. The flow module shall include an internal desiccant cartridge with a replaceable hydrophobic filter to protect the atmospheric reference from moisture. Sensor materials exposed to the flow stream shall be epoxy, stainless steel, polyvinyl chloride (PVC), and chlorinated polyvinyl chloride ( CPVC).
