IFM Electronic Efector 300 - Empty Pipe Detection

8
- Flow according to the marked flow direction (arrow "flow direction"): meter
adds�
- Flow against the marked flow direction: meter subtracts�
The meter saves the totalled consumed quantity every 10 minutes� After a power
failure this value is available as the current meter reading� So the possible data
loss can be maximum 10 minutes�
The current meter reading can be evaluated via an external parameter setting
software(→10.6.5ActivatingtheIO-Linkcommunicationinterface).
4.5 Temperature monitoring
An analogue signal (4���20 mA) can be provided on output 2 for temperature moni-
toring.Ontheanaloguefunctions→4.7).
4.6 Empty pipe detection
Theunitdetectswhenthetwoelectrodesarenotwettedbythemedium(→4.1
Measuring principle for volumetric flow monitoring)� The empty pipe detection can
beactivatedordeactivated(→10.5.7).Ifitisactiveandthepipeisempty,theunit
reacts as follows:
> [SEnS] is indicated in the display�
> The flow is set to zero�
Theemptypipedetectioncanbesetastime-dependingornottimedepending(→
