Application: ultrasonic Measurement of Canal Depth

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.

Material: PZT-51 (equal to PZT-5A)

PZT -51 is equal to PZT-5A, with low aging rate, extremely stable performance and high frequency requirement etc. transducers
