Operation
Operation: Operation state in which output is being correctly output
Interlocked to input: Operation state in which the same processing as when there is no alarm is performed
Example 1) The volumetric flow rate also is held if the vortex frequency to be input is held when the volumetric
flow rate is in use.
Example 2) When a Temperature sensor failure occurs
When the vortex flowmeter is used for the volumetric flow rate, the vortex frequency to be input becomes
normal action and the volumetric flow rate also becomes normal action.
When the vortex flowmeter is used for the mass flow rate, temperature and pressure are to be input in addition
to the vortex frequency. Accordingly, the combination becomes vortex frequency (normal), temperature (error)
and pressure (normal). Output becomes the mass flow rate calculated according to the temperature error as a
result of specifying handling of the temperature error by setting in Temp sensor alarm action.
