The Pulsar MantaRay is a portable area-velocity meter and measures flow in open channels, partially filled, and surcharged pipes using a submerged ultrasonic sensor. 
 
The unit is designed for flow surveys in open channels, partially full sewer pipes, and surcharged pipes - making the portable open channel flow meter suitable for sewer monitoring, industrial flow monitoring, irrigation flow, and natural streams.
 
The Pulsar 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.
