Application of Time Difference Ultrasonic Flowmeter in Large Channels
The time difference ultrasonic flowmeter is widely used in hydrologic measurement because of its versa-tility,high precision,easy to use,non-invasive installation and other advantages.In the hydrological flow moni-toring of large channels,the time-difference ultrasonic flowmeter can provide high precision flow measurement results.Aiming at the fluctuation error which may occur in practice,the method of fluctuation error correction is put forward,and the application scheme of ultrasonic flowmeter with time difference method is designed and compared with the conventional method.The results show that the time difference ultrasonic flowmeter conforms to the current standard with higher efficiency and better effect,and is worthy of application and popularization.
