9.1.3 Electrode coating detection
This function offers the ability to detect coatings on measuring electrodes by reference to a configurable
maximum threshold.
When the configured threshold is exceeded, an alarm is triggered via the programmable output, depend-
ing on the configuration.
Conditions for using the function:
• JUMO flowTRANS MAG S02:
The function is available in the nominal width range DN 10 to 300 (3/8 to 12 inch).
• JUMO flowTRANS MAG H02:
The function is available in the nominal width range DN 10 to 100 (3/8 to 4 inch).
• Maximum signal cable length in case of remote mount design type: 50 m (164 ft).
• For this function, the conductivity of the measurement medium must be between 20 µS/
cm and 20,000 µS/cm.
Additional installation conditions:
• For plastic pipelines, a grounding washer must be deployed upstream and downstream of the de-
vice.
9.1.4 Conductivity monitoring
The conductivity of the measurement medium is monitored by means of a configurable minimal/maximal
threshold.
If the value exceeds or drops below the configured threshold, an alarm is triggered via the programmable
output, depending on the configuration.
Conditions for using the function:
• JUMO flowTRANS MAG S02:
The function is available in the nominal width range DN 10 to 300 (3/8 to 12 inch).
• JUMO flowTRANS MAG H02:
The function is available in the nominal width range DN 10 to 100 (3/8 to 4 inch).
• Maximum signal cable length in case of remote mount design type: 50 m (164 ft).
• For this function, the conductivity of the measurement medium must be between 20 µS/
cm and 20,000 µS/cm.
Additional installation conditions:
• For plastic pipelines, a grounding washer must be deployed upstream and downstream of the de-
vice.
• The measuring electrode must be free of deposits.
