Flow Control/Monitoring Equipment - Greyline Instruments MantaRay

The MantaRay portable area-velocity flowmeter from Greyline Instruments is designed for monitoring stormwater, sewage, industrial effluent, irrigation water, and natural streams through open channels, partially full sewer pipes, and surcharged pipes without a flume or weir. It uses a submerged ultrasonic sensor, which is hydrodynamically shaped and designed to shed deposits and stringers for reliable operation. To calibrate, enter the pipe diameter or channel dimensions; the unit automatically computes and displays the flow rate and total on its backlit LCD display. It allows users to monitor flow in real time, and displays and datalogs flow rate and total flow. It is powered by built-in, rechargeable batteries, or it can be connected externally to 12- or 24-volt DC batteries or a battery charger for continuous operation with 4-20 mA and relay outputs for connection to samplers, SCADA and telemetry systems. 888/473-9546; www.greyline.com.
