IM3000 Installation Manual
Grounding
When grounding on metal pipe, the electric potential of the fluid, meter and surrounding pipe must be equalized.
This is done by connecting the ground wires on the flowmeter body to one of the lug locations on the mating
flange connection.
NOTE:
Make sure the ground wire or lug is between the flange bolt head (or nut) and the outside surface of the
mating pipe flange. This grounding must be completely isolated from the flowmeter. (See the following diagram.)
With plastic pipe, a grounding rod or other ground-to-earth connection must be installed.
