Acoustic flow measurement plays an important role in helping ensure optimal operating conditions for hydroelectric plants, water treatment plants and irrigation canals. Suspended particles as well as air bubbles interfere in the operation of the plant as well as the function of acoustic flow measurement.
Within the scope of this project it is to be analyzed how the acoustic signals, used in the Transit Time technique, (incl. Forward scattering by particles) and the reflected signals, used in the doppler method, can be used in combination in order to broaden the application field of the flow rate sensor as well as deliver information regarding the water conditions. The operation in a clamp-on arrangement (non-wetted sensor) is also a subject of investigation.
