Note 1) The flow rate measurement range can change depending on the setting.
Note 2) For the type with unit switching function [The type without the unit switching function will have a fixed SI unit (l/min or l).]
Note 3) The system accuracy when combined with sensor unit.
Note 4) The output functions operate only for the real-time flow rate display, and do not operate for the accumulated flow display.
Note 5) Window comparator mode –– Since hysteresis is 3 digits, separate P1 and P2 by 7 digits or more. 1 digit is the minimum setting unit (refer to the table above).
Note 6) The flow rate unit is based on 0°C and 101.3kPa.
