A look into the future.

GWF is at the forefront of innovative flow technologies, products and solutions. We measure anywhere: in rivers, channels, and partially filled or pressurized pipes. Ultrasound propagates through fluid media as pressure waves. Our instruments are able to convert information gained from measuring the behaviour of these waves into flow speed. There are two main measurement principles on which our instruments are based. Applying the Transit Time technique, we measure the time of flight with and against flow direction. When using the Pulse-Doppler effect, our instruments record the change of the signal frequency reflected by a particle in the flow.
