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.
