Measuring flow in open channels with an ultrasonic hydrodynamic level and velocity sensor
Portable Open Channel Flow Meter
Designed for flow surveys in open channels, partially full sewer pipes, and surcharged pipes. MantaRay is ideal for stormwater, sewage, irrigation water, and natural streams.
Ultrasonic hydrodynamic level and velocity sensor
The MantaRay uses a submerged ultrasonic sensor to continuously measure both velocity and level in the channel. The sensor resists fouling, corrosion, and abrasion.
View real-time flow rate and total flow on the large backlit LCD display. Connect to samplers or SCADA and telemetry systems with the 4-20mA and relay outputs. Download flow log files to a USB memory stick.
Portable, flow monitor for partially filled pipes & open channels
Easy to Use
The MantaRay portable area-velocity flowmeter the greyline mantaray portable area-velocity flow meter measures both level and velocity to calculate flow in an open channel or pipe.
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. 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.
