Conventional ultrasonic flow sensors measure flow by recording the time it takes for an ultrasonic pulse to travel from a transmitter to a receiver. At higher flow rates, the signal is accelerated and the transmission time decreases. This transmission time is directly related to the instantaneous flow. The FD-R series improves this detection method by sending two signals simultaneously (one ultrasonic pulse moving in the direction of flow and another signal moving in the opposite direction). The delta of the received signals serves as the basis for flow detection. This means that the measured values remain consistent and stable, regardless of external factors such as deposits and temperature changes.
