Abstract
PURPOSE: To detect the depth of water from the saturation temperature of a sealed liquid continuously by using a vacuum container in which a liquid is sealed and a liquid heater and a thermometer are installed.
CONSTITUTION: When the outer cylinder 1 is attached to the pump in the bottom of the excavated well, the water pressure in the place acts on the pressure plate 11 through the hole 2 of the sensor chamber 3, and balances the pressure of saturated vapor in the vacuum container 5, the thermometer 7 inticates the saturation temperature. Next when the heated water in the container 5 is cooled, its temperature drops, the pressure plate 11 is raised by the water pressure, the operating rod activates the limit switch 9, the liquid heater 6 heats the water, the pressure of saturated vapor increases, the pressure plate 11 is pushed downwards and returned to the balancing location again. In this way, the water pressure can be calculated from the saturation temperature of sealed heated water to know the depth of water by converting the calculated result.
