使用地磅校准ACE低温液体计量系统

Using Loadometer to Calibrate ACE of Measuring Cryogenic Liquid

槽车上加装的低温液体流量计取代地磅来计量卸载的液态气体质量已经成为大势所趋,但是如何检定此类低温液体流量计却成为了一个难题,本文通过地磅探索出一个能有效校准低温流量计的方法,为此交易类流量计有效监管指明了方向,同时为实现今后对此类流量计的检定迈出了一步。

It ll be more and more popular that flowmeter is installed on the tank to measure the mass of the cryogenic liquid instead of using loadometer, but it becomes a task how to verify it. This paper focuses on this problem and finds a practical and effective way to calibrate this meter of ACE by loadometer, and shows a method about how to supervise this kind of flowmeter. Also it means a step forward to achieve verification of this meter.
