range.
Use this flow switch under the specified operating temperature
range.
Withstand pressure is 2.25 MPa.
Do not install a flow switch at a foothold position.
Install a flow switch so that the flow direction agrees with the
arrow direction on the side of the body.
Mount the body so that the bottom of the body does not face
