真实的气体质量流量可以用代塞尔(Desset)公司的台特曼脱利克(Datemetric)分部所开发的新型传感器系列来测量。这类传感器对气体的压力和温度极不敏感。它们所采用的是声称为独特的旁路结构。831型传感器在诸如气体混和、扩散炉 Real gas mass flow can be measured using a new line of sensors developed by Desmet’s Datemetric division. Such sensors are extremely insensitive to the pressure and temperature of the gas. What they used was what they claimed to be a unique bypass structure. 831 sensors in such as gas mixing, diffusion furnace
