*1: Refer to page 25 [Applicable fluids list].
*2: When fluids with high temperature are used, the available pressure range will be reduced. (See
[operating pressure range] on page 28 for details.)
*3: The response time is when the set value reaches 63% in relation to the step input. There might be a
0.05 seconds delay at response time of 0.25s or 0.5s due to the timing of internal processing.
*4: The enclosure rating includes the digital flow switch with a lead wire with M12 connector.
*5: When options are used, add the weight of the option parts.
