Set Point Range and Rated Flow Range

Set the flow rate within the rated flow range.
The set point range is the range of flow rate that can be set in the switch.
The rated flow range is the range that satisfies the switch specifications (accuracy, linearity, etc.).
It is possible to set a value outside of the rated flow range if it is within the set point range, however, the satisfaction of specifications can
not be guaranteed. The flow range if using CO

the rated flow range
*1 The analog output current from the connected equipment should be 20 μA or less when selecting 0 to 10 V.
When 20 μA or more current flows, it is possible that the accuracy is not satisfied at less than or equal to 0.5 V.
* D or H fluctuates depending on the setting of the zero cut-off function.
When the zero cut-off function is set to "0," the flow rate display value starts from 0 L/min., but in conditions other than
horizontal installation and supply pressure of 0.35 MPa, the output may not be 0 L/min.
