Area-velocity flow meter MantaRay

ultrasonicfor waterfor wastewater

The Greyline MantaRay 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 Greyline MantaRay displays and datalogs flow rate and total flow, as well as, connects to samplers, SCADA, and telemetry systems. The Greyline 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 hydrodynamically shaped and designed to shed deposits and stringers for reliable operation in sewage, stormwater, and stream flow applications. Measures flow in partially filled pipes and open channels No flume or weir required 4-20 mA and Relay outputs for connection to Samplers and SCADA Powered with built-in rechargeable NiMH batteries 2 million point data logger with USB output to Flash drives Backlit LCD display for flow rate, totalizer and menu system Channel Types - Round pipe, rectangular, trapezoid, egg, or custom shapes Electronics Enclosure - IP 67 polycarbonate Accuracy - Level: ±0.25% of range or 1 mm (0.04 in). Velocity: ±2% of Reading Repeatability & Linearity ±0.1%
