Stingray 2.0 Portable Level-Velocity Logger

Brand: Pulsar Measurement

The Greyline Stingray 2.0 is a compact, portable, battery-powered (4 standard Alkaline D-cell batteries) logger with an ultrasonic sensor. 

It data logs level, velocity, and water temperature readings for flow monitoring through open channels, partially full sewer pipes, and surcharged pipes. 

Use it for flow surveys, I & I studies, stormwater, irrigation water, and sewage.

Greyline Stingray 2.0 uses a submerged ultrasonic sensor to continuously measure both velocity and level in the channel. 

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. 

The sensor mounts inside the pipe or at the bottom of an open channel. 

A stainless steel mounting bracket is included.
