Ultrasonic Flowmeter Application :
Ultrasonic water flow meters measure the speed of fluid passing through the pipe using ultrasound to measure the volumetric flow. 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. In its most basic form, the time for the sonic pulse to travel downstream is compared to the time for the pulse to travel upstream. Using this differential time, the velocity of the following fluid is calculated. Then the meter calculates the volumetric flow rate in the pipe using this fluid velocity. In addition, BTU energy measurement can be derived from the volumetric flow rate and the temperature difference between the hot and cold legs. Clamp-on ultrasonic meters can measure water from outside of the pipe by shooting pulses of sound through the pipe walls, thus having application flexibility and making them suitable for water flow measurements in large pipes.
