The accuracy of drum level measurement was approved by Northeast Electric Power Research Institute
After Qinhuangdao Measurement &Control Equipment Co., Ltd retrofits No.4 boiler drum water level measurement system of Tongliao General Power Plant, Northeast Electric Power Research Institute makes a lot of field experience, aiming at the existing deviation problem of water level measurement. According to the analysis about the experimental data and DCS curve of more than 40 day historical data , Northeast Electric Power Research Institute draws a preliminary conclusion:“Thermal water level measuring circuit has no problem, it could reflect the real change condition of drum water level,each difference of indication between water level gauge is the true deviation of the water level in the boiler drum.”This conclusion is the Northeast Electric Power Research Institute for the first time affirmed accuracy of drum level measurement in the form of text .
