Portable ultrasonic open channel flow-meter Greyline Instruments

Stingray Portable Open Channel Flow Logger

A new, portable logger for area-velocity flow surveys in sewers, open pipes and channels. Stingray is designed for municipal stormwater, combined effluent, raw sewage, irrigation water and stream flow.

Stingray uses a submerged ultrasonic sensor to measure both Velocity and Level in the channel. It is mounted in the channel with a stainless steel bracket or a pipe band. No calibration is required. It operates up to 4 years powered by standard Alkaline D-cell batteries. Electronics are housed in a watertight IP67 enclosure and rated for operation from –15° to 60°C.

Each Stingray includes Greyline Logger software to retrieve and display logged data by RS232 or modem connection. The software calculates flow for round, rectangular, trapezoid and egg shaped channels plus flumes and weirs. After the data is downloaded, the software automatically creates a flow chart based on the pipe or channel size. The software displays it as a graph or a table, or you can export it to a spreadsheet program.
