Title:
DEVICE AND METHOD OF DETECTING FLOW RATE/LIQUID KIND, AND DEVICE AND METHOD OF DETECTING LIQUID KIND
Document Type and Number:
WIPO Patent Application WO/2005/005971
Kind Code:
A1
Abstract:
[PROBLEMS] A compact flow rate/liquid kind-detecting device capable of detecting a flow rate of a fluid while detecting a liquid kind and concentration of the fluid, and accurately and quickly detecting the flow rate, liquid kind, and concentration of the fluid. [MEANS FOR SOLVING PROBLEMS] A flow rate/liquid kind-detecting device has a main flow path where a fluid to be detected is circulated, an auxiliary flow path branched from the main flow path, and a flow rate/liquid kind-detecting sensor device provided in the auxiliary flow path. In performing either liquid kind detection or concentration detection of the fluid to be detected or both of them, an auxiliary flow path opening/closing valve is closed to cause the liquid to temporarily stay in the flow rate/liquid kind-detecting sensor device and either of the detection or both are performed. In detecting the flow rate of the fluid to be detected, the auxiliary flow path opening/closing valve is opened to allow the fluid to circulate in the flow rate/liquid kind-detecting sensor device and the flow rate is detected.
