The principle of measurement is also referred to as the transit-time difference method. Using this technique, ultrasound pulses are transmitted alternately through the liquid in the direction of flow and against it. The sensors work variably as transmitter and receiver. The transit time of the sound signals filtered through the medium in the direction of flow is shorter than that against it. The difference in transit time ?t is measured and can be used to calculate the average flow velocity on/over the sound path. Flow rate is determined by the measured flow velocity and the calculated pipe cross-section.
