The Technologists from A.yite (America) Laboratory, have done much efforts to design portable ultrasonic flowmeter, we would like to supply suitable measurement for the travelling engineer.

We design 2 type portable flowmeter for differential require, one is handhold ultrasonic flowmeter, the other is portable flowmeter. The Portable Flowmeter will be easy to move, suitable for a working team; the Handhold Flowmeter is easy pick up, suitable for single person.

The ultrasonic flow meter works with Ultrasonic Technology and Measures by Principle of time difference. There is a pair of ultrasonic vibrator and receiver in the exterior of pipe emitting in two directions and both face to face. The light vibrator will emit ultrasonic signals down stream and reversed stream. Measuring the time difference of the two directions transmission, you will get the flow rate of the fluid; then input the diameter of pipe, you will get the flow.

There is no moving part in the ultrasonic instrument, which is a kind of movable and reliable static instrument. With its accuracy up to 0.8% and comparatively large dynamic measurement range as well as a 30-year-stability, it becomes a proud of the flow measurement instrument outside of pipe in current market.
