More Information
Summary:To enable to count the number of opening and closing of an electromagnetic valve, and to determine exactly a time for inspection or a life time of an air drive valve and the electromagnetic valve for example by utilizing an accumulated number of the air drive valve or the electromagnetic valve, which is used in an automatic liquid feeding apparatus under operation, opened and closed for a definite time. In a method for counting opening and closing of the valve in the automatic liquid feeding apparatus, a liquid storing part 1 and a processing part 2 are connected with a piping 3 through the air drive valve 4 on the liquid storing part side or/and the processing part side. The method has a non-contact type DC electric current sensor 8 applied to the automatic liquid feeding apparatus for feeding a compressed gas to the air drive valve 4 from the electromagnetic valve 5 controlled by a controlling device 7, and afterward arranged on wiring 6a-6c connecting the controlling device 7 and the electromagnetic valve
