4.3.8. The need for protective grounding is determined by power supply and
environment conditions under which the flow meter is operated.
The protective grounding and earthing device should correspond to
the rules on design of power electric installations. Do not use the light-
ning protection system for grounding since in could result in device's
failure.
As a grounding wire, you must use a copper ground wire between
the flowmeter and grounding device. If mechanically protected, its
cross-section must be minimum 2.5 mm
2
. Minimum 4 mm
2
cross-
section is required for installations without protection.
The grounding conductor is connected to the earthing terminal of
the CS.
