市场上热量表种类繁多,计量原理也不尽相同,但主要分为机械式和超声式两种。新疆地区采暖周期长,机械式热量表和超声式热量表都得到了广泛的应用。但是在长期的使用过程中,这两种表的使用寿命及计量性能如何,却没有相关的实验研究。笔者针对使用了3年的800块机械式热量表和500块超声式热量表进行复检,根据复检结果研究这两种热量表的使用寿命。同时从中各抽样选取6块表,
On the market a wide variety of heat meters, measurement principles are not the same, but mainly divided into two kinds of mechanical and ultrasonic. Long heating cycle in Xinjiang, mechanical heat meters and ultrasonic heat meters have been widely used. However, in the long-term use of these two tables of life and measurement performance, but no relevant experimental study. I used for three years, 800 mechanical heat meter and 500 ultrasonic calorimeter for re-examination, according to the re-examination of the results of these two heat meter life. At the same time from each sample select 6 tables,
