Abstract
PURPOSE: To enable calibration even during operation of the plant, without dismounting the pressure gauge being calibrated from the piping, by applying the calibration pressure to the pressure gauge being calibrated through a diaphragm of pressurizer.
CONSTITUTION: When calibrating a pressure gauge 1 during operation of the plant, first a valve 3 is closed, then a diaphragm 10 abuts against the face 9a of chamber 9 side while the pressure of process fluid is being applied to chamber 8 of the pressurizer 5. Then, valves 14, 15 are opened, and pressurizing fluid 16 in a pressure source 17 is sent into the chamber 9 of the pressurizer 5. At this time, when the pressure of the pressurizing fluid 16 becomes larger than that in the chamber 8 spaced from the diaphragm 10, the diaphragm 10 departs from the face 9a. The indication pressure gauge for calibration 18 at this time corresponds to the indication of the pressure gauge 1.
