Description:
Ultrasonic flowmeter is an instrument that measures flow by detecting the effect of fluid flow on ultrasonic beam (or ultrasonic pulse).Ultrasonic flowmeter, like electromagnetic flowmeter, is a kind of flowmeter which is suitable for solving the difficult problem of flow measurement because there is no obstructing device in the flow channel of the meter.
Advantage:
Ultrasonic flowmeter is a kind of non-contact instrument, which can be used to measure not only the flow of medium with large pipe diameter but also the measurement of medium that is not easy to be touched and observed.
Its measurement accuracy is very high, almost not subject to the various parameters of the measured medium interference, especially can solve other instruments can not strong corrosive, non-conductive, radioactive and flammable and explosive medium flow measurement problems.
