Model No.: OD100*200KHz PZT-51
Piezoelectric ceramic disc
Quick shipments
High performance
wrapped arround electrode available
Application: ultrasonic flowmeter
Compared with traditional flow meter method, buoy method and ultrasonic method, modern river flow measurement technology is faster, more efficient and more accurate. With the support of computer technology, the test instrument can not only collect a large amount of data at any time and place, but also overcome the influence of water pulsation and other factors, which makes people refreshed. At present, there are two kinds of river flow measurement techniques commonly used in our country, one is using radar velocimeter to test and the other is using acoustic Doppler velocimeter to test.
