Time-Difference Ultrasonic Open-Channel Flowmeter (Medium Range)

The time-difference method for flow measurement is widely used to determine the flow rate in 60-degree cross-sections of various rivers, channels, and pipelines. It is particularly well-suited for tidal river reaches with complex flow patterns and both forward and reverse currents, and can also be applied to flow measurements in partially filled pipelines.
