热能表投入生产前须进行型式试验,对产品实行全性能检测,尤其是计量性能,检测条件覆盖了热能表流量范围、温度范围、温差范围。介质温度规定:常温、(50±5)℃、(85±5)℃,对检测介质温度范围的规定,主要针对热能表使用工况进行的,如果试验合格,则
Before the heat meter is put into production, the type test must be carried out to test the full performance of the product, especially the metering performance. The test conditions cover the flow range, temperature range and temperature difference of the heat meter. The provisions of the medium temperature: room temperature, (50 ± 5) ℃, (85 ± 5) ℃, the provisions of the test medium temperature range, mainly for heat meter operating conditions, if the test pass
