Document Type and Number:
WIPO Patent Application WO/2019/172138
Kind Code:
A1
Abstract:
[Problem] To provide a liquid agent application system that can detect the liquid level height easily and precisely. [Solution] A liquid agent application system 1 comprises a head 10, a reservoir tank 20, a tube pump 40, an atmospheric pressure sensor 50, and a control unit 70. The tube pump 40 regulates the volume of gas in a reservoir chamber 21. The control unit 70 supplies liquid agent from the reservoir tank 20 to the head 10 by way of driving the tube pump 40. The control unit 70 detects the total cumulative drive volume Pa of the tube pump 40 as a value that indicates the liquid level height L of the liquid agent in the reservoir tank 20.
