Ultrasonic Water Meter Principle

An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow.

Ultrasonic water meter principle.

Ultrasonic flow meter working principle. 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. There are two conditions in the pipe like no flow and flowing. 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 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. 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. How to use ultrasonic flowmeters.

The open channel flowmeter is based on the specific shape of the parshall metering groove weir plate metering groove. Ultrasonic flowmeters are available in sizes to 72 inches and larger. Velocity water area 3600 seconds instantaneous flow rate cubic meters hour ultrasonic open channel flow meter working principle. Transit time designs are also available to measure gas and.

Shmeters ultrasonic water meters. The working principle of ultrasonic flow meter is it uses sound waves to resolve the velocity of a liquid within a pipe.
