Extended diagnostic functions
Overview
Note
• The extended diagnostic functions are only available on the
ProcessMaster FEP630 and HygienicMaster FEH630 if the
‘Extended diagnostic functions’ software package has been
ordered (see table) .
• The ‘Partial Filling Detector’ function is not available for
HygienicMaster FEH630.
• To facilitate initial commissioning, the individual diagnosis
options of the extended diagnostic functions are deactivated
(factory default).
• Each diagnostic function (e.g. Gas Bubble Detector or
Electrode Deposit Detector) can be individually activated.
Once activated, the diagnostic function must be calibrated
according to the conditions on site and the limit values must
be set.

Filling function (optional) Filling function
Detection of partial filling
A partially filled sensor influences the measured values of the
flow meter as well as the measuring accuracy.
If the flowmeter sensor is ordered with a full pipe detection
electrode located at the top of the flowmeter sensor, the
function ‘...Diagnosis Tfe’ of the transmitter triggers an alarm
when the meter tube goes into partial filling.
Requirements for use:
• Nominal diameter: > DN 50 (> 2 in)
• Flowmeter sensor Design Level A
• Conductivity of the measuring medium:
20 to 20000 μS/cm
Installation conditions:
• The flow sensor must be installed horizontally with the
terminal box pointing upwards.
Setup
The partial filling detection must be matched to the measuring
medium on site.
Menu / parameter Description
Diagnostics / ...Diagnosis Control / ...Diagnosis Tfe
Tfe On/Off Activate the function.
Start Tfe Adjust Automatic adjustment of the TFE function.
Prior to starting, make sure that:
• There is no flow
• Sensor is completely filled
Manual Tfe Adjust Manual adjustment of the TFE function.
Tfe Threshold Manual fine adjustment of the switching
threshold.
Actual Tfe Value Display of the current TFE value.
Above the TFE threshold, an alarm occurs, if
configured.
