Popis: Based on the analysis of the high temperature high pressure heater level switch fault in the Conventional Island of the 1000 MW nuclear power unit, this paper adopts optimization of instrument selection by replacing level switch with level transmitter. By comparing the working characteristics of three most commonly used transmitters, guided wave radar liquid level transmitter is finally selected to improve the measurement reliability and stability of unit operation. The application of guided wave radar has provided the reference engineering experience for subsequent new projects or in service transformation.
