Note 1) 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 2) The output functions operate only for the real-time flow rate display, and do not operate for the accumulated flow display.
Note 3) Window comparator mode — Since hysteresis will reach 3 digits, keep P1 and P2 apart by 7 digits or more. The minimum setting unit is 1 digit. (Refer to the table above.)
∗ Flow rate units measured under the following conditions: 0°C and 101.3kPa.
