Note 4) Accumulated flow rate is reset when the power supply is turned OFF.
Note 5) Switch output and accumulated pulse output can be selected during initial setting.
Note 6) Window comparator mode: Since hysteresis (H) will reach 3 digits, keep P_1 and P_2 or n_1 and n_2 separated by 7 digits or more. (In the case of OUT2, n_1 and n_2 will become n_3 and n_4, P_1 and P_2 will become P_3 and P_4.)
Note 7) All flow switches conform to the CE marking.
