Area Velocity flow meters AVFM 5.0

Specifications

Area-Velocity Flow Meter
Monitor flow through open channels, partially full sewer pipes and surcharged pipes a flume or weir. Ideal for municipal
stormwater, combined effluent, raw sewage and irrigation water.

Submersible Ultrasonic Sensor
The AVFM 5.0 uses a submerged ultrasonic sensor to continuously measure both Velocity and Level in the channel. The sensor resists fouling, corrosion and abrasion. The flowmeter can be configured with the standard submerged velocity-level sensor, or with submerged velocity plus a separate non-contacting ultrasonic level sensor.
View flowrate and total flow on the large backlit LCD display and connect to external devices with three 4-20mA outputs and two control relays.
