3.7.6

Ground for devices with hard rubber lining

For devices with meter sizes DN 125 and larger, the liner contains a conductive element. This
element grounds the measuring agent.
3.7.7

Ground for devices with protective plates

The protective plates are used to protect the edges of the liner in the measuring tube, e.g., for
abrasive fluids. In addition, they function as a grounding plate.
• For plastic or pipes with insulating lining, electrically connect the protective plate in the same
manner as a grounding plate.
3.7.8

Ground with conductive PTFE grounding plate

For devices with a meter size between DN 10 ... 150, grounding plates made of conductive
PTFE are available. These are installed similar to conventional grounding plates.
