Measure flow through partially filled pipes, channels, canals and turnouts without a flume or weir. Ideal for wastewater, stormwater, effluent, industrial wastewater and irrigation water. Configuration is simple: enter the pipe diameter or channel shape and the AVFM 6.1 computes the flow volume and displays the flow rate. Measure forward and reverse flow and calibrate to channels of any shape.

The AVFM 6.1 uses a submerged ultrasonic sensor to measure both Velocity and Level in the channel. The sensor is completely sealed with no orifices or ports. It mounts inside a pipe or at the bottom of a channel.
