This compact new meter operates on standard alkaline batteries
for extended time periods to log level, velocity and water
temperature in open channels, partially full sewer pipes and
surcharged pipes without a flume or weir. It is designed for
municipal stormwater, combined effluent, raw sewage, irrigation
water and stream flow.
Stingray uses a submerged ultrasonic sensor to continuously
measure both Velocity and Level in the channel. The sensor has
no moving parts and is resistant to fouling and corrosion.
