Set the flow rate within the rated flow range.
The set flow range is the range of flow rate that is possible in setting.
The rated flow range is the range of flow rate that satisfies the sensor product specifications (such as accuracy, repeatability).
It is possible to set a value outside of the rated flow range if it is within the set flow range, however, the specification is not be guaran-
teed.

1. After the power is turned on, the switch’ s output re-
mains off while a message is displayed. (Approx. 3
sec.) Therefore, start the measurement after a value
is displayed.
2. Perform settings after stopping control systems.
3.
Keep the switch away from the strong magnet and mag-
netic field to prevent the switch from malfunctioning.
