Introduction:

   Ultrasonic flowmeter fluid flow through the detection of the ultrasonic beam ( or ultrasonic

pulse)  effect  to  measure the flow meter.  Ultrasonic flowmeter is a kind of non-contact

instrument, it canbe the medium flow measurement with large diameter  can also be used to

measure  is not  easy to contact and observation of medium. Its measuring accuracy is high,

the interference is almost not  affected   by   various  parameters  of  the  measured  medium,  especially  can  solve  other instruments not  strong corrosive, non conductivity, radiation and flammable and explosive mediumflow  measurement.
