Filling liquid that wish to so that may dispensing to syringe of dispenser and dispensing because done pressure and time control and dispensing amount adjustment is depended on dispensing pressure, dispensing time and inside diameter of needle. Pressure that is supplied in syringe is regulated being proportional at open and shut time of high pressure of air regulator, low pressure adjustment and solenoid valve, and make and break of solenoid valve consists by existence point of contact and nothing point of contact switch. In this paper, automatic control system and process workers manufacture automatically work little more easily and conveniently, used syringe dispenser for column of water difference that use interactive algorithm way applicationintensity factor are presented and applied to several practical examples to demonstrate their accuracy.
