The MantaRay Portable Area-Velocity Flow Meter measures flow in open channels, partially filled and surcharged pipes using an ultrasonic sensor. It's designed for monitoring stormwater, sewage, industrial effluent, irrigation water and natural streams. The MantaRay displays and datalogs flow rate and total flow and connects to samplers, SCADA and telemetry systems.

Calibration is simple: enter the pipe diameter or channel dimensions and the MantaRay automatically computes and displays the flow rate and total on its backlit LCD display. Mount the sensor at the bottom of the pipe or channel and hang the IP67 electronics case above the high water level.
