基于静态质量法的微小水流量标准装置设计与试验

Design and Test of Micro Water Flow Standard Device Based on Static Mass Method

本文首先介绍了微小水流量标准装置的技术指标、装置的组成和原理,进行了换向器试验、最大流量稳定性试验、最小流量稳定性试验。试验结果表明,该装置可以开展(0.01~200)L/min范围的科里奥利质量流量计、液体容积式流量计、涡轮流量计、涡街流量计、超声流量计、浮子流量计等的检定/校准工作。

This paper first introduced the technical index,composition and pri nciple of the micro water flow stand-ard device.The commutator test,maxi mum flow stability test and minimum flow stability test were carried out.The test results showed that the device can carry out the verification/calibration of Coriolis mass flowmeter,liquid volumetric flowmeter,turbine flowmeter,vortex flowmeter,ultrasonic flowmeter and rotameter in the rangeof(0.01~200)L/min.
