Mantaray Portable Area-Velocity Meter

The Greyline MantaRay displays and logs flow rate and total flow, as well as being able to connect to samplers, SCADA, and telemetry systems, making site integration simple and easy. The submerged ultrasonic sensor continuously measures flow or reverse flow in partially filled or surcharged pipes and is a completely sealed unit with no orifices or ports. The ultrasonic sensor is hydrodynamically shaped and designed to shed deposits and stringers for reliable operation in sewage, stormwater, and stream flow applications.

Features

• 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
