可移动式燃气表高低温准确度检测装置的研制及推广

The development of high/low temperature accuracy for removable gas meter

环境温度对燃气表的计量性能有何影响、影响多大,是一个值得探讨的问题。研制一套标准装置,检测燃气表在高低温环境下的计量性能,对实际生活和工业中的燃气计量有着非常重要的意义。

The influence of gas temperature to the metering performance of diaphragm gas meter is a problem worthing analysis. Developing a suit of device which can detect the metering performance of the diaphragm gas meter in high or low temperature environment is very important to actual gas metering.
