Potential equalization via ground terminal and pipe flanges
1. Connect both sensor flanges to the pipe flange via a ground cable and ground them.
2. If DN ≤ 300 (12"): Mount the ground cable directly on the conductive flange coating
of the sensor with the flange screws.
3. If DN ≥ 350 (14"): Mount the ground cable directly on the metal transport bracket.
Observe screw tightening torques: see the Sensor Brief Operating Instructions.
4. Connect the connection housing of the transmitter or sensor to ground potential by
means of the ground terminal provided for the purpose.
Plastic pipe or pipe with insulating liner
This connection method also applies in situations where:
• The customary potential equalization is not used
• Equalizing currents are present

Potential equalization via ground terminal and ground disks
1. Connect the ground disks to the ground terminal via the ground cable.
2. Connect the ground disks to ground potential.
Pipe with a cathodic protection unit
This connection method is only used if the following two conditions are met:
• Metal pipe without liner or pipe with electrically conductive liner
• Cathodic protection is integrated in the personal protection equipment
