Analysis on measurement error of online chemical instruments of water steam system and improvement methods

Abstract

Abstract: Abstract:The situation of measurement error of the online chemical instruments of unit No.1 water steam system in a power plant was introduced. The reasons of the measurement error were analyzed. The improvement methods to reduce measurement error were proposed. After the methods were adopted, the measurement accuracy of the online chemical instruments of the power plant was improved, and the reliability of the water steam chemical supervision was ensured.
