Saturated steam has the following characteristics ① to-one correspondence between the saturated steam temperature and pressure, there is only one independent variable therebetween. ② readily condense saturated steam, if heat loss during transmission, and lead to lower temperature and pressure. Strictly speaking Yunnan vortex flow meter quote, more or less of saturated steam or liquid droplets containing a two-phase fluid mist, so, to describe the different states can not use the same gas equation of state. ③ accurate measurement of saturated steam flow more difficult, because the saturated steam dryness is difficult to guarantee, the general flow meter can not accurately detect the two-phase fluid flow in Yunnan vortex flow meter retail, steam pressure fluctuations will cause steam density changes, the meter shows value generating additional error. So steam measurement in Yunnan vortex flow meter selection, we must try to keep the measuring points dryness steam to meet the requirements, compensation measures should be taken, if necessary, to achieve accurate measurements.
