Greyline Mantaray Portable Area-Velocity Flow Meter

Greyline Mantaray Portable Area-Velocity Flow Meter

The Mantaray Portable Area-Velocity Flow Meter measures flow in open channels, partially filled and surcharged pipes using an ultraosnic sensor. The unit displays and datalogs flow rate and total flow and connects to samplers, SCADA and telemetry systems.

Calibration is simple: enter the pipe diameter or channle dimensions and the MantaRay automatically computes and displayes 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.

The Mantaray uses a submerged ultrasonic sensor to continuously measure flow or reverse flow in open channels, partially filled or surcharged pipes. The sensor is a completely sealed ultrasonic unit with no orifices or ports. It is hydronamically shaped and designed to shed deposits and stringers for reliable operation in sewage, stormwater and stream flow applications.

The QZ02L sensor mounts inside the pipe or at the bottom of an open channel. No special compounds, tools or hardware are required. A stainless steel mounting bracket is included and a size of range optional pipe bands are available for sensor installation in manholes.
