Schematic view of a flow sensor. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and ...
In case of a perfect fully developed real velocity profile of Ultrasonic meter which is shown in Fig.(7) indicating a possible sound path as a result of an installation in a real flow. Figure (7) showing Ultrasonic meter sound path - fully developed flow. Here a mathematical derivation for this Ultrasonic meter is also becomes very complicated.
Sonar flowmeters have the capacity of measuring the velocity of liquids or gases non-intrusively within the pipe and then leverage this velocity measurement into a flow rate by using the cross-sectional area of the pipe and the line pressure and temperature. The principle behind this flow measurement is the use of underwater acoustics.

Ultrasonic water meters are highly accurate devices, with residential models capable of measuring flow rates as low as 1 liter per hour (L/h). [2] They feature wide flow measurement ranges, require minimal maintenance, and have long lifespans due to the absence of internal mechanical components that could wear out over time. [3]
Ultrasonic sensors are also used to detect intruders; the ultrasound can cover a wide area from a single point. The flow in pipes or open channels can be measured by ultrasonic flowmeters, which measure the average velocity of flowing liquid. In rheology, an acoustic rheometer relies on the principle of ultrasound.
For submerged flow, a secondary head measurement (Hb) is required to determine the flume is submerged and the degree of submergence. The primary point of measurement (Ha) is located in the inlet of the flume, two-thirds of the length of the converging section from the flume crest.
