Calibration system immersion-type water level measuring device, calibration method, calibration program, has the device of the measurement of calibration function with immersion-type thus thus

摘要

PROBLEM TO BE SOLVED: To provide a calibration system for immersion-type water level measurement device, which calibration system makes it possible to remotely calibrate the detection unit of an immersion-type water level measurement device without taking out the detection unit, and also to provide a calibration method and calibration program for the water level measurement device and an immersion-type water level measurement device with calibration function.SOLUTION: A calibration system 10 calibrates an indicated value of a water level displayed on a display unit 26 with respect to an immersion-type water level measurement device comprising: a detection unit 24 which seals with a sensor the inside of a housing having a part thereof opened to a liquid to detect a differential pressure P between a water pressure applied on the pressure sensor from the liquid and an atmospheric pressure Preceived internally from a hollow cable 23 connected to the housing; and the display unit 26 for displaying the water level of the liquid on the basis of the differential pressure P between the water pressure and the atmospheric pressure P. The calibration system 10 comprises: a measuring device 11 for measuring the water pressure applied on the detection unit 24; a measurement unit 11bfor applying the measured water pressure Pfrom the hollow cable 23; and a correction unit 12 for correcting the indicated value to read the zero point when the measured water pressure Pis applied.
