*1: Flow rate converted to volumetric flow rate at 20°C, 1 barometric pressure (101 kPa). Full scale stands for max. scale flow rate in the flow rate range.
*2: Use dry gas which does not contain corrosive elements such as chlorine, sulfur or acids, and which is clean and does not contain dust or oil mist.
*3: Standard differential pressure is the differential pressure when this product is calibrated. (Secondary side released to atmosphere)
*4: Working pressure differential is the differential pressure required for normal operation of this product. Note that the values depend on the flow rate range and
applicable fluids. The min. value of the working pressure differential is the differential pressure required for the full scale flow rate to flow when secondary side
is released to atmosphere. The max. working pressure (max. value of working pressure differential) is the max. value of primary side pressure. If more pressure
is applied, control may become unstable, or the max. flow rate may not be controllable.
*5: Ensure that the current supply capacity per IO-Link master port is sufficient.
*6: This product's protection circuit is effective only for specific misconnections. It does not provide protection for all misconnections.
*7: The accumulated flow is a reference value. It is reset when the power is turned OFF.
*8: The valve inside this product cannot be used as a stop valve requiring zero leakage. Slight leakage is allowed for in the specifications.
