Kalashnikov A.А.  The features of hydrostatic level measuring at NPP

A metrological analysis of hydrostatic level measuring technique is undertaken with respect to NPP measuring channels. The paper shows the relationships between the systematic components of the level measurement error and: (a) thermochemical characteristics of the working fluid, (b) process tank level, (c) measuring channel settings. The relationships obtained enable high-precision estimation of the measuring channel’s error and the calculation of relevant correction factors to be entered in NPP control systems.

Keywords: NPP, process control system, hydrostatic level measuring, systematic measurement error.
