Note 1) Flow rate display can be switched between the basic condition of 0°C, 101.3 kPa and the standard condition (ANR) of 20°C, 101.3 kPa, and 65% RH.
Note 2) For digital flow switch with unit switching function. (Fixed SI unit [(

)] will be set for switch type without the unit switching function.)
Note 3) The high flow rate type is CE marked; however, the linearity with applied noise is ±5% F.S. or less.
Note 4) Switch output and accumulated pulse output selections are made using the button controls.
Note 5) The analog output operates only for real-time flow rate, and does not operate for accumulated flow.
