2. For best results flow should be evenly distributed across the channel and relatively free of turbulence. (The AVFM 5.0 is very effective at averaging level and velocity readings in turbulent conditions, but best accuracy and response time is achieved with evenly distributed flow.) 3. - Page 20 AVFM 5.0 Area-Velocity Flow Meter Page 20...

Page 25: Field Troubleshooting
AVFM 5.0 Area-Velocity Flow Meter FIELD TROUBLESHOOTING The AVFM 5.0 uses an ultrasonic level sensor to determine channel AREA and an ultrasonic Doppler sensor to measure flow VELOCITY. The QZ02L sensor combines both sensors in one housing. An optional configuration uses the PZ15-LP “down-looking” level sensor and a QZ02L-DP velocity sensor. - Page 26 AVFM 5.0 Area-Velocity Flow Meter SENSOR CABLE RESISTANCE TEST Unplug the green sensor terminal from the Doppler board and connect the sensor wires as shown. With a multimeter, perform resistance checks for each set of wires. One single loose terminal may cause false readings.
