1.5 ADDITIONAL HARDWARE THAT MAY BE REQUIRED
1.5.1 Grounding Rings
Grounding rings may be required whenever meters are installed in non-metallic or lined pipes.
Grounding rings placed before and after the meter eliminate electrical noise that will interfere
with the proper operation of the meter. ONICON provides grounding rings as an optional
accessory. Grounding ring dimensional information and part numbers are listed below. For proper
operation, grounding rings are required before and after the meter.
