Handheld Ultrasonic Flow Meter

Description
The transit time flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a distance from each other. The transducers can be mounted in V method in which case the ultrasound transverses the pipe twice, or W method in which case the ultrasound transverses the pipe four times, or in Z method in which case the transducer are mounted on opposite sides of the pipe and the ultrasound transverses the pipe only once. The selection of mounting method depends on pipe and liquid characteristics. When flow meter works, two transducers transmit and receive the ultrasonic signal which travels firstly downstream and then travels upstream. Because ultra sound travels faster downstream than upstream, there will be a difference of time of flight (delta t). When the flow is still, the time difference (delta t) is zero. Therefore, as long as we know the time of flight both downstream and upstream, we can work out the time difference and the flow velocity (V) and flow volume (Q) the following formula.
