The Greyline Stingray 2.0 is a portable level-velocity logger. Offering open channel flow measurement, the Stingray 2.0 is compact, portable, and battery-powered! Using four standard Alkaline D-cell batteries, the unit is a complete area-velocity logger with an ultrasonic sensor that data logs level, velocity, and water temperature for flow monitoring through open channels, partially full sewer pipes, and surcharged pipes.
Ideally used for flow surveys and studies, I&I (Inflow and Infiltration) studies, CSO monitoring, stormwater runoff, irrigation water, and permit compliance. The submerged ultrasonic sensor continuously monitors both level and velocity in the channel with no calibration required. The Stingray 2.0 portable open channel level-velocity logger stores 130,000 data points and offers USB data download to view real-time level and velocity readings, view the remaining logger and battery capacity, and set the logging interval.
This compact, portable area-velocity logger is designed for flow measurement in applications without a flume or weir, especially stormwater, combined effluent, raw sewage, irrigation water, raw sewage, and streamflow.
