以湿式气体流量计为例,选取工作压力、流量点以及累积流量三个主影响因素,利用钟罩式气体流量标准装置对其进行正交试验。得出三个影响因素对湿式气体流量计示值误差都有一定的影响,其中工作压力的影响最大,流量点的影响最小。本试验为今后产品的设计、生产及检定(或校准)提供数据支持,为相关试验研究提供参考。 Taking the wet gas flowmeter as an example, the three main influencing factors of working pressure, flow point and cumulative flow were selected, and the orthogonal experiment was carried out by using bell-type gas flow standard device. It is concluded that the three influencing factors have a certain impact on the indication error of the wet gas flowmeter, of which the working pressure has the greatest impact and the flow point has the least impact. This test provides data support for the design, production and verification (or calibration) of the product in the future, providing reference for the related experimental research.
