|Flow Switches

When reducing the flow rate of an IFW510 series flow switch, the indicator needle and the scale plate interfere with each other. What can be done to remedy this?

When the product is used with an inlet pressure exceeding 0.2 MPa, it may be difficult to set the operating flow rate to a low flow rate as there may be interference between the lower limit slit on the scale plate and the indicator needle, making it impossible to set the value.
If this happens, remove the cover of the flow switch, and follow the setting procedure. Keep in mind that the scale plate is merely for use as a guide.
