3.1 Bonding/Grounding
Caution. For safety reasons and optimum performance, the flowmeter, pipelines and medium must be
correctly bonded and grounded according to regulations.
Note.
 The flow sensor must not be connected to a ground spike.
 For bonding connections use ≥4mm2 (<10AWG) cable.
 Sensors ≤80mm do not require grounding rings.
 Connect the transmitter ground connection to the flowmeter body ground – see Fig. 3.6 and
Fig. 3.7.
