Ultrasonic water meter
An ultrasonic water 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 against the direction of the flow or by measuring the frequency shift from the Doppler effect.
Ultrasonic water meter Overview
Vortex flowmeters are used in numerous branches of industry to measure the volume flow of liquids, gases and steam. Applications in the chemicals and petrochemicals industries, for example, in power generation and heat-supply systems involve widely differing fluids: saturated steam, superheated steam, compressed air, nitrogen, liquefied gases, flue gases, carbon dioxide, fully demineralized water, solvents, heat-transfer oils, boiler feedwater, condensate, etc.
Ultrasonic water meters Principle
Ultrasonic water meters measure the difference between the transit time of ultrasonic pulses propagating with and against the flow direction. This time difference is a measure of the average velocity of the fluid along the path of the ultrasonic beam.
