AVFM-II Area-Velocity Flow Monitor

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

The AVFM-II 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 a pipe or at the bottom of a rectangular, trapezoid or egg-shaped channel. Calibration is simple: enter the pipe diameter or channel width and the AVFM-II computes the flow volume and displays the flow rate.

Greyline Pipe Band Sensor Mounting for Area-Velocity Flowmeters

Do it the easy way - use a stainless steel pipe band for Area-Velocity Flow Meter sensor mounting. You can install the sensor and tie wrap the cable in place before you enter the manhole. Then insert the pipe band into the manhole inlet pipe and tighten the scissor-jack to expand the band for a friction fit inside the pipe.

Pipe Mounting Bands are available from Greyline in a range of sizes for common pipe diameters.
