Abstract

A method and a system for controlling automatic quantitative fluid supply are disclosed, and the method and the system automatically control the quantitative fluid supply by timing a period of time t required for introducing gas () into a sealing tank () in such a way that the pressure in the sealing tank () reaches a default value and calculating a period of time T, required for continuously introducing the gas () into the sealing tank () to extrude a fixed volume (V) of the fluid, from the time t, in the process of automatic quantitative fluid supply, so as to automatically control the switching-on and -off of a gas passage (), overcome the impact of the reduction of the liquid level on the quantitative supply accuracy and guarantee the accuracy requirement of repeated quantitative supply.
