RUF100 Ultrasonic Flow Meter

Ultrasonic flowmeters, as the name suggests, are meters that use sound waves to measure flow. These meters are attached around the inside or outside of a pipe, and when activated, transmit ultrasonic waves from one side of the meter to the other. These transmitted waves are then collected and measured to determine the flow.
