|Flow Switches
There are no restrictions with air flow switches.
(Regarding the PFMB/PFMC series, vertical mounting can be set by using the F31 orientation correction function. This enables the display error to be reduced when the flow rate is zero.)
We recommend that when the piping runs in the vertical direction you install a flow switch for water in such a way that the fluid flows from bottom to top. Also, to ensure that the flow rate is detected normally, you must install the product in such a way that the flow detection part is always filled with water.
