Installation
Before you mount a flow switch, read "SAFETY" and "Installation" described in this chapter carefully to obtain safe and correct measurement.
Mounting
●Use this flow switch under the specified operating pressure 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 upward.
●Provide a straight pipe length of more than eight times the pipe diameter to upstream and downstream of the flow switch.
●Set Display Part proper position taking the cable entry and display position into account. Display Part rotates in 270 degree.
Piping connections
●Observe the specified tightening torque when connecting pipes. Refer to the following table for the appropriate torque values.
Nominal size of screws | Appropriate tightening torque | |
(N・m) | ||

|
| |
Rc 1 | 36 to 38 | |
|
| |
Rc 1・1/2 | 48 to 50 | |
|
| |
Rc 2 | 48 to 50 | |

●When connecting pipeline to the switch, apply a spanner to the metal part of the piping section for the switch.
●Make sure that sealing tapes will not enter inside the pipe when connecting pipes.
