THE CORRECTION OF READINGS OF MEASURING CHANNELS LEVEL WITH DIFFERENTIAL PRESSURE SENSORS AT NPP
(pp. 69-75)

Abstract. This paper is devoted to the correction of readings of measuring channels level at NPP. Proposed correction methods are based on the correction factors entrance in the program-technical equipment from the structure of modern measuring channels of APCS NPP. The correc-tion factors calculation can be performed in a static (for nominal characteristics of the operating environment only) and dynamics in view of the current values of operating environment characteristics at each time point. This correction method, in contrast to others, allows to get the real level of readings in different operation modes of technological equipment. Also, it increases the accuracy of automatic control and optimizes commission works.

Keywords: NPP, APCS, level measuring by hydrostatic method, correction of reading level sensors.
