AVFM 5.0 Area-Velocity Flow Meter FUSE REPLACEMENT 1. Turn OFF power. 2. Loosen cover screw and open. 3. Remove power module. 4. Locate fuse on Power Board. 5. Replace fuse with 2 AMP/ 250V, 5 x 20mm fuse. 6. Reinstall power module into chassis.
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 transducer combines both sensors in one housing. An optional configuration uses the PZ12-LP “down-looking” level sensor and a QZ02L-DP velocity sensor.
