Greyline Stingray 2.0 flow loggerGreyline's new portable Stingray 2.0 is a compact, battery-powered area-velocity flow logger. 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.

The Stingray 2.0 uses a new and improved submerged, steel reinforced, PVC ultrasonic sensor to measure both velocity and level in the channel. No calibration is required. It operates up to 4 years on standard alkaline D-cell batteries. The complete system is housed in a watertight, IP67 enclosure and rated for operation from –4 to 140 F. Each Stingray 2.0 includes Greyline Logger software to retrieve and display logged data via USB output. The software calculates flow for round, rectangular, trapezoid and egg shaped channels plus flumes and weirs.
