The OTT Sonicflow using the ultrasonic travel time principle is designed for continuous discharge measurements in rivers, canals and streams. Thanks to up-to-date ultrasonic technology and smart signal processing, the rugged measuring system provides precise values even in shallow waters. It can be used for waters between 5 m and 200 m in width.
Ultrasonic travel time system for rivers from 5 to 200 m width. Required minimum water level of 16 cm. Very low power consumption. Robust and flexible transducer mounting structures. Compatible with OTT data logger.
± 10 m/s
± 1 % of measured value ± 2 mm/s
Compact, modular system design: allows for individual configuration according to type of water and requirements
Rugged transducer support: optimum protection and precise sensor alignment
Only little sensor coverage necessary: can also be used in shallow water
Intuitive calibration software: professional calibration of the measuring system as well as easy-to-use management of measuring cross-section and system parameters
Low power consumption: optional battery or solar operation
Examples of Use
Continuous discharge measurement in open channels and canals, also in shallow, wide waters, tidal areas, estuaries (backwater, changes in direction of flow)
Reliable discharge control in cooling water canals, e.g. in power stations
Precise control of tidal gates, sluices, dams, sample collectors etc.
Precise flow measurement for controlling irrigation canals
