Abstract

PURPOSE:To make changing-over of detecting water levels possible with simple constitution by providing an air chamber via an air hose and a solenoid valve to a water level detector. CONSTITUTION:A pressure sensitive switch 4 is connected via an air hose 3 to an air trap 1 communicating with the bottom part of a vessel 2, and an air chamber 5 is connected thereto via an air hose 6 branched from the hose 3 and an electromagnetic stop valve 7. The water level H of the vessel 2 of the time when the switch 4 operates is higher in a water level H1 when the valve 7 is opened than in a water level H2 when the valve 7 is closed. If the volume of the chamber 5 is taken sufficiently large with respect to the volume of the air trap 1, the difference between H1 and H2 can be taken large. Thereby, the changing-over of the detecting water levels is made possible with the simple constitution.
