Calibration:
The minimum and maximum operating flow rates are given in the table below. Adjustments should be
carried out as follows: turn the calibration screw (A) in a clockwise direction for the contacts to close at
higher flow rate values or in a counterclockwise direction for lower flow rate values. When the adjustment
has been made lock the screw (A) with the locking ring nut (B). Avoid all contact with the presetting
screw (C) . An incorrect setting would seriously impair the operation of the switch.
