2.5.2 Conductive Pipeline
If the meter is included as part of a conductive pioeline that is not electrically insulated from the liquid
to be metered, the following grounding procedure should be followed. Refer to Figure 2-6 to
supplement the text.
1) Drill and tap both pipeline flanges adjacent to the bonding connections on the flowme-
ter. The lugs on the bonding cables are sized for a 1/4 inch bolt.
2) Obtain a bright metal surface around the edges of the both tapped holes with a file or
emery cloth.
3) Attach the bonding wire and another length of ground wire to the flanges as shown.
Use internal tooth lockwashers as shown in the detail. The wire to the good external
ground should be #12 AWG, or heavier, copper wire.
