AVFM 6.1 Area-Velocity Flow Monitor
- Sensor Protection
IP68 for continuous submersion in liquids. - Flow Calculation
Single sensor measures velocity and level to calculate the flow. - Applications
For partially filled and surcharged pipes - Datalogger
Built in 2 million point datalogger
The Greyline AVFM 6.1 Area-Velocity Flow Meter uses a submerged ultrasonic sensor measuring both level and velocity to calculate flow in an open channel or pipe. 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 dimensions and the AVFM 6.1 automatically computes and displays flow volume.
The ultrasonic sensor mounts inside the pipe or on the bottom of a channel with a stainless steel mounting bracket (included) and a single screw into the bottom of the pipe or channel. No special compounds, tools or hardware are required. The sensor is completely sealed with no orifices or ports.
