Creeks, Streams and Wadis

Also natural stream courses and courses of a river can be supervised with ultrasonic measuring instruments. However, on this occasion, the volume can be calculated only estimated, because ground unevennesses, obstacles like stone, uncompleted branches and also turbulence which influences measuring results. Also the area state can change by violent rainfall, thaw and also by natural disasters fast.

Hence, measuring results in connection with natural stream courses or courses of a river must be already looked under normal terms always as approximate values. If the area state, by external influence has completely changed, the won approximate values are not usable any more.











Stingray and dry riverbeds

One customer is using multiple Stingrays in desert areas to monitor dry riverbeds that contains water only during times of heavy rain. Water level, velocity and temperature are logged. A computer system is used to store and analyse the logged information.

The Stingray, a 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.
