容积式流量计具有很高的测量精确度,但在小流量时流量特性变坏。本文介绍了这种流量计的工作原理和特点,并叙述了音速文丘里标定结果和其它带有伺服流量计在高压1Mpa 时的标定系统。
Volumetric flowmeters have high measurement accuracy, but flow characteristics deteriorate at low flow rates. This paper describes the working principle and characteristics of this flowmeter, and describes the calibration results for sonic velocities and other calibration systems with servo flowmeters at high pressures of 1 MPa.
