Title:
FLOW SWITCH AND FLOW SWITCH ATTACHMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/199838
Kind Code:
A1
Abstract:
This flow switch is for detecting the flow of a fluid flowing inside a tube which is flexible and has a bending portion, and the flow switch comprises a sensor for detecting deformation of the tube. The sensor is fixed to the outer circumferential surface of the tube in the bending portion. As viewed along a first direction in which the fluid flows, the outer circumferential surface has: a first area positioned in a second direction from the center of the tube; and a second area positioned in a third direction from the center of the tube. The second direction and the third direction orthogonally intersect with the first direction. The third direction is a direction opposite to the second direction. The bending portion has a bending shape projecting in the second direction, and the sensor is fixed to the first area.
