Grounding

All flowmeters must be properly grounded to avoid personnel shock hazard.

The ground conductor should not transmit any interference voltages, therefore do not
ground any other electrical devices together with this conductor.
Repeater power supply unit

Protective separation (PELV) must be ensured
(VDE 0100 / VDE 0106 or IEC 364 / IEC 536, or equivalent national regulations).

For measurement reasons, connect an FE functional ground conductor.
