- For Open Channels and PipesNo Flume or Weir Required
- Ultrasonic - Measures Velocity + Level to Calculate Flow
- Works in partially filled and surcharged pipes
- Measures Forward and Reverse Flow
- 4-20mA or 0÷5V  commutable Output
- 2 Control Relays
- Optional built-in 2-million point Data Logger

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. Calibration is simple: enter the pipe diameter or channel shape and the AVFM 5.0 computes the flow volume and displays the flow rate. Measure forward and reverse flow and calibrate to channels of any shape.
Area-Velocity - How It Works
The MantaRay uses a submerged ultrasonic sensor to measure both Velocity and Level in the channel. The sensor is completely sealed with no orifices or ports. It mounts inside a pipe or at the bottom of a channel. 

Application Consideration Sealed Ultrasonic Sensor Measures Level and Velocity.The MantaRay is recommended for pipe diameters greater than 6" (150 mm). Maximum pipe diameter or channel width should not exceed 10 ft (3 m) unless flow velocity is evenly distributed across the channel width. Avoid sensor mounting locations where sediment builds up and locations where there is an elevation drop or bend immediately upstream from the sensor. Maximum pipe or channel slope should not exceed 3%.
The MantaRay measures flow velocity from 0.1 to 20 ft/sec (0.03 to 6.2 m/sec) and reverse flow up to 5 ft/sec (1.5 m/sec).
