| Abstract: | The measurement accuracy of the drum level is directly related to the safe and stable operation of the thermal power unit. Therefore, it is very important to take some necessary measures to improve the measurement accuracy of the drum level. This paper introduces the common measurment methods of the drum level, the causes of the measurement errors and the check and calculation methods of the measurment errors. The general principle and test method of the actual compensation of the drum level is presented in this paper. |
