Application for Ultrasonic Gas Flowmeter :
Ultrasonic meters are commonly used for custody transfer and fiscal oil and gas measurement. They measure the velocity of a fluid in a closed pipe and utilize transducers to emit ultrasonic pulses (greater than 20 kHz frequency) from which the flow meter can calculate the average velocity along the path of the beam of ultrasound. The fundamentals of ultrasonic meters make them suitable for gas or liquid measurement, treating them both as fluids.
