Please Note:This model has been replaced by the new
Greyline AVFM 5.0 Area-Velocity Flow Meter. Parts, service
and tech support for the AVFM-II are available from Greyline.

Isolated 4-20mA Outputs (Flow, Level and Velocity)
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.
Portable data logging model...
Check out the portable,
battery-powered Stingray
Level-Velocity Logger for flow surveys and I&I studies. It runs
for up to 4 years on a set of standard D-Cell Alkaline
batteries.
