Ultrasonic Water Meter Application :
Ultrasonic water meter: Ultrasonic water meter uses an ultrasonic transducer, to send ultrasonic sound waves through the fluid, to determine the velocity and translate the velocity into measurement of the water volume. The ultrasonic meter has a sensor that can be either inserted inside or attached outside of the pipe. The sensor measures the water velocity in the pipe and then converts this into flow rate. Ultrasonic water meters are typically very accurate. In addition, they have wide flow measurement ranges, require little maintenance, and have long lifespans due to the lack of internal mechanical components to wear out.
