jWAVE Bluetooth Portable Ultrasonic Flow Meter

The transit time flow meter operates by alternately transmitting and receiving a burst of sound energy between the two transducers.  The burst is first transmitted in the direction of fluid flow and then against fluid flow.

Since sound energy in a moving liquid is carried faster when it travels in the direction of fluid flow (downstream) than it does when it travels against fluid flow (upstream), a differential in the travel times will occur. The sound’s travel time is accurately measured in both directions and then used to compute the flow rate.

Sound waves can bounce in many directions as they travel through various materials. The more the sound waves scatter, the fewer actually reach the second transducer. The jWAVE uses sophisticated methods to maximize transducer efficiency, thus allowing the unit to run on very low power. Focusing of the sound wave is also important to ensure it reaches the second transducer without degrading. This is accomplished by accurately spacing the transducers to allow for optimum sound transit between transducers. The jWAVE app computes this spacing based on the pipe size, pipe material, and type of liquid.
