Measures velocity & level to monitor flow with a single ultrasonic sensor
Area-velocity flow meter
Measure flow through open channels, partially full pipes, and surcharged pipes without a flume or weir. Ideal for wastewater stormwater, effluent, industrial wastewater, and irrigation water.
Submersible ultrasonic sensor
The AVFM 6.1 uses a submerged ultrasonic sensor to continuously measure both velocity and level in the channel. The sensor resists fouling, corrosion, and abrasion. The flow meter can be configured with the standard submerged velocitylevel sensor, or with submerged velocity plus a separate noncontacting ultrasonic level sensor, for highly aerated fluids or those with a high concentration of suspended solids.
View flow rate and total flow on the large backlit LCD display and connect to external devices with three 4-20mA outputs and two control relays. Flow rate, volume, run hours, and diagnostic information available through the optional Modbus RTU serial communications.
Ultrasonic flow monitor for partially filled pipes & open channels
Easy to use
The AVFM 6.1 Area-Velocity Flow Meter measures both level and velocity to calculate flow in an open channel or pipe.
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.
