4.5 Potential equalization
To obtain optimum results from the measuring system, the sensor must have the same
electrical potential as the liquid being measured.
This is achieved by means of built-in grounding electrodes.

Cathodic protected piping
Special attention must be paid to systems with cathodic protection
WARNING
Use in hazardous area!
Cathodic pipe protection is not allowed in hazardous areas
