4.4  Grounding and equipotential bonding

In the case of compact flowmeters and measuring units with flange connections, the flow sensor 
is conductively connected to the pipeline. For compact flowmeters and "sandwich" type 
measuring units, a separate conductor connected either to the internal or external PA terminal 
must be provided to connect to the equipotential bonding.

For remote systems with pressure sensor, the connection of the flow sensor can either be made 
via the PA connection in the converter's terminal compartment or via the external PA 
connection.

CAUTION!

Vortex signal converters and flow sensors must be included in on-site equipotential bonding 
system acc. to EN 60079-14! They are connected to the PA terminals.
