The Greyline AVFM monitors flow through open channels, partially full sewer pipes and surcharged pipes without a flume or weir. The AVFM is ideal for municipal stormwater, combined effluent, raw sewage and irrigation water.

The AVFM uses a submerged ultrasonic sensor to continuously measure both velocity and level in the channel. The sensor is resistant to fouling and corrosion. It is tolerant of turbulence and high approach velocity. It can be configured with the standard submerged velocity-level sensor, or with submerged velocity plus a seperate non-contacting ultrasonic level sensor.
