Potential equalization via measuring tube
Unlined and ungrounded metal pipe
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 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.
Pipe with insulating liner or plastic pipe
This connection method also applies in situations where:
• Standard company potential equalization cannot be guaranteed
• Equalizing currents can be expected
