Note 1) 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 2) The system accuracy when combined with PFW5.
Note 3) The output functions operate only for the real-time flow rate display, and do not operate for the accumulated flow display.
Note 4) 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).
