CALIBRATION SUPPORT DEVICE OF PRESSURE TYPE LEVEL GAGE AND CALIBRATION SUPPORT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a calibration support device capable of precisely verifying a value measured by a pressure type level gage installed in the depth of a conduit with a simple device and method.;SOLUTION: A sensor 101 having plural individual electrodes 132 which are disposed in line in a vertical direction beside a vertically long common electrode 131 is installed adjacent to a position where a pressure type level gage is installed in a conduit. Indicator lamps 231 which are conductively connected to the individual electrodes 132 in one-to-one relation are all connected to the common electrode 131 being interposed by a DC power source PS to allow a current to flow between the common electrode 131 and the individual electrodes 132 immersed in water to turn on the indicator lamps 231 corresponding to the individual electrodes 132 immersed in water. Since the position of the individual electrodes 132 immersed in water in the conduit is indicated by the corresponding indicator lamps 231 which are lit, the water-level in the conduit is precisely indicated by the lit indicator lamps 231.;COPYRIGHT: (C)2014,JPO&INPIT
