1.3.3 Grounding of primary head

•

All flowmeters must be grounded.

•

The grounding conductor should not transmit any interference voltages.

•

Do not ground any other electrical device together with this conductor.

•

The primary head is connected to ground by means of an FE functional ground conductor.

•

Special information on grounding various primary heads is contained in the separate installation instructions for primary heads.

•

These instructions also contain detailed descriptions on how to use grounding rings and how to install primary heads in metal or plastic pipes or internally coated pipelines.

IMPORTANT!

For EEx versions, also pay regard to all special directions included in Sect. 6.1 and 13.

Only the EEx primary head may be installed in the hazardous area. The signal converter must be installed outside the hazardous area!
