LIQUID DELIVERY METHOD, LIQUID DELIVERY SYSTEM, AND COMPUTER-READABLE STORAGE MEDIUM

摘要

A liquid delivery system enables liquid to be delivered using a simple configuration thereof. The liquid delivery method comprises: a process of enabling the liquid to circulate into a tube in accordance with pressure of gas filled in an inner space between an outer surface of the tube and a housing for a tube covering an outer side of the tube having elasticity; a process of obtaining a size of the pressure of the liquid circulating inside the tube as a first value; a process of obtaining the size of the pressure of the gas filled in the inner space as a second value; and a process of calculating a difference between the first value and the second value as a third value; and a process of detecting a state of the tube based on the third value.
