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.
No flume or weir required – submersible ultrasonic sensor measures velocity and level simultaneously to calculate flow. No moving parts to wear, foul, or clog.
The built-in 5-button keypad, intuitive menu, and large backlit LCD display make the Greyline AVFM 6.1 the most operator-friendly area velocity flow meter on the market.
Fast, simple, installation and set-up.
Improved performance in a wider range of operating conditions.
At a glance, view flow rate, velocity, level, totalizer, relay status, and important diagnostic information on the LCD display.
Three isolated 4-20 mA outputs for flow rate, velocity, and level, and two relay outputs for pulse output or alarm.
6.5 million point data logger for greater flexibility of data monitoring, control, and reporting.
