Note 1) Fixed SI unit [l/min or l] will be set for switch types without the unit switching function. (“-M” is suffixed at the end of part number.) Accumulated flow is reset when the
power supply turns OFF.
Note 2) If Vcc side on sensor input connector part is short-circuited with 0V side, the flow monitor inside will be damaged.
Note 3) Switch output and accumulated pulse output can be selected during initial setting.
Note 4) The system accuracy when combined with applicable flow sensor.
Note 5) This product conforms to the CE mark.
