目前我国煤气流量计量绝大多数采用孔板节流装置,也有一小部分使用涡街流量计。但上述测量装置存在工况不稳定,流量变化大,能源损耗大,安装检修运输不便等问题。我们采用热导式质量流量计直接测量煤气的质量流量,无须进行温压补偿,稳定可靠。并且热导式质量流量计结构简单,不存
At present, the vast majority of China’s gas flow metering orifice plate throttling device, there is a small part of the use of vortex flowmeter. However, the above measuring apparatus has problems such as unstable conditions, large flow rate changes, large energy loss, inconvenience in installation, maintenance and transportation. We use the thermal conductivity mass flowmeter direct measurement of the gas mass flow, without temperature and pressure compensation, stable and reliable. And the thermal conductivity mass flow meter structure is simple, does not exist
