... Do not disassemble or modify the main body. Warning 1. Check regulators and the flow adjustment valves before introducing the fluid. If pressure or flow rate beyond the specified range are applied to the switch, the sensor unit may be damaged. [For air] 2. Fluids for measurement for this digital flow switch are nitrogen and air ...

... Avoid sources of surge generation and crossed lines. 4. Switches are not equipped with surge protection against lightning. Flow switches are CE compliant; however, they are not equipped with surge protection against lightning. Lightning surge protection measures should be applied directly to flow system components as necessary ...

... The rated flow rate range is the range of flow rate that satisfies the specifications (accuracy, linearity, etc.) of the sensor. Although it is possible to set a value outside the rated flow rate range, the specifications will not be guaranteed even if the value stays within the regulating flow rate range. ...
