Ultrasonic Water Meter Principle

Ultrasonic flow meter working principle.

Ultrasonic water meter principle.

Ultrasonic water flow meters measure the speed of fluid passing through the pipe using ultrasound to measure the volumetric flow. It guarantees a certain liquid level and knows a certain flow rate. 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 against the direction of the flow. How to use ultrasonic flowmeters.

Ultrasonic flowmeters are commonly applied to measure the velocity of liquids that allow ultrasonic waves to pass such as water molten sulfur cryogenic liquids and chemicals. An ultrasonic flow meter construction can be done by using upstream and downstream transducers sensor pipe and reflector. The working principle of ultrasonic flow meter is it uses sound waves to resolve the velocity of a liquid within a pipe. Shmeters ultrasonic water meters.

The meter is battery powered and can work uninterruptedly for 10 years with only one battery. In a transit time ultrasonic liquid flow meter an ultrasonic signal is transmitted in the direction of the flowing fluid downstream and then another signal is transmitted against the flowing fluid upstream. Under various pipe flow conditions this ultrasonic water meter for industrial and commercial purposes is capable of marking design section measurements with the highest possible measuring accuracy. The open channel flowmeter is based on the specific shape of the parshall metering groove weir plate metering groove.

There are two conditions in the pipe like no flow and flowing. Ultrasonic flowmeters are available in sizes to 72 inches and larger.
