Ultrasonic Flow Meter Basics

The video tutorial explains how ultrasonic signals are used to measure the flow rate of water in a pipe. Two signals are emitted: one travels downstream with the water, and the other travels upstream against it. When water is not flowing, both signals take the same time to travel. However, when water flows, the downstream signal is faster. This concept is likened to a boat traveling with or against a river current. By measuring the time difference between the signals, the velocity of the water can be determined, which, along with the pipe's cross-sectional area, is used to calculate the volume flow rate.
