The method of adjustment of regulating system immersion-type water level measuring device it is identical, adjust program it is identical, and with regulatory function immersion-type measure device

摘要

PROBLEM TO BE SOLVED: To provide a regulation technique of an immersion-type water level measurement device capable of performing highly accurate correction with respect to an indicated value of a water level even when a density gradient occurs in liquid being a measuring object of the water level.SOLUTION: A regulation system 10 comprises: three or more water pressure measuring instruments 50fixed on an outer surface of a detector (detection section 24, transmission line 29) immersed into storage liquid at different water depths; a density derivation section 47 for deriving two or more density of the liquid on the basis of mutual differences among measured water pressures Pmeasured by at least three of the water pressure measuring instruments 50and water depth differences of the water pressure measuring instruments 50; a density averaging section 49 for averaging the two or more density derived by the density derivation section 47 and driving average density of the liquid; and a correction section 48 for correcting an indicated value of a water level of the liquid on the basis of the average density.SELECTED DRAWING: Figure 4
