Dry Calibration Method for Large-Size Multi-Channel Ultrasonic Flow Meters

通过理论分析和大量的实验研究，为多声道超声流量计干校验法提供了依据。

The calibration for large-size flow meters is a difficult technical problem all over the world. Since the development of modern science and technology and the accumulation of practical experiences, the multi-channel ultrasonic flow meter can be calibrated by the use of dry calibration method. This paper describes the principle and practical experiences both in China and abroad on dry calibration method for multichannel ultrasonic flow meters.
