AVFM Area-Velocity Flow Monitor

Submersible 
Ultrasonic 
Sensor Monitor flow through open channels, partially full sewer pipes and surcharged pipes without a flume or weir. Ideal for municipal stormwater, combined effluent, raw sewage and irrigation water. 

Uses a submerged ultrasonic sensor to continuously measure both Velocity and Level in the channel. The sensor is a completely sealed ultrasonic unit with no orifices or ports. It mounts inside the pipe or at the bottom of a rectangular channel. No special compounds, tools or hardware are required. The AVFM sensor is tolerant of turbulence and high approach velocity.
