Hysteresis mode: adjustable (can be set from 0) Window comparator mode
Note 5)
: fixed (3 digits)
Note 1) The value varies depending on set flow range
Note 2) For digital flow switch with unit switching function. (Fixed SI unit [
l/min or l] will be set for switch types without the unit switching function.)
Note 3) The system accuracy when combined with PF2D5.
Note 4) Switch output and accumulated pulse output can be selected using the control button operation during initial setting.
Note 5)
Window comparator mode: Since hysteresis (H) will reach 3 digits, keep P_1 and P_2 or n_1 and n_2 apart by 7 digits more. (In case of output OUT2, n_1, 2 to be n_3, 4 and P_1, 2 to be P_3, 4.)
Note 6) The display unit conforms to the CE mark.
Note) Accumulated flow rate is reset when the power supply turns OFF.
