Caution
Set Flow Rate Range and Rated Flow Range
Set the flow rate within the rated flow range.
The set flow rate range is the range of flow rate that can be set on the controller side.
The rated flow range is the range that satisfies the sensor’s specifications (accuracy, linearity etc.).
It is possible to set a value outside off the rated flow range, however, the specification is not be guaranteed.
Warning
Measured Fluid Others
1. Check regulators and 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.
2. Be sure to take measures to prevent exposing
the switch to inflammable and/or explosive
gases when using inflammable fluid.
3. Install a filter on the inlet side when there is a
possibility of condensation and foreign matter
being mixed with the fluid.
If foreign matter adheres to the switch’s vortex generator or
vortex detector, accurate measurement will no longer be
possible.
Warning
1. After the power is turned on, the switch’s
output remains off while a message is
displayed. Therefore, start the measurement
after a value is displayed.
2. Perform settings after stopping control
systems.
When the switch’s initial setting and flow rate setting are
performed, output maintains the condition prior to the settings.
Output turns OFF when the switch’s initial setting and flow rate
setting are preformed.
