Siemens SITRANS F M MAG 1100 - Potential Equalization Methods

4.8 Potential equalization
To obtain optimum results from the measuring system, the sensor must have the same
electrical potential as the liquid being measured.
Graphite EPDM or PTFE gaskets
Electrically
conductive
piping
Potential equalization with electrically
graphite gaskets
Potential equalization using earth strap
supplied
Electrically
non-conductive
piping
Potential equalization with electrically
conductive graphite gaskets
Potential equalization using separate
potential equalization ring
NOTE
For unidirectional flow use two ground‐
ing rings
NOTICE
For sizes DN 2-10 with Hastelloy or stainless steel adaptors potential equalization is done
ensured through adaptors
Cathodic protection
Special attention must be paid to systems with cathodic protection
WARNING
Use in hazardous area!
Cathodic pipe protection is not allowed in hazardous areas
