Grounding rings are used to suppress electrical interference at the installation location for electromagnetic ﬂow meters. They are provided in pairs and are installed upstream and downstream of the ﬂow meter. ONICON grounding rings are ﬂat wafer-style rings designed to be installed between an ANSI Class 150 ﬂange and the F-3000 series inline electromagnetic ﬂow meter ﬂange face. The same grounding rings may also be sandwiched between ﬂange pairs located upstream and downstream of F-3500 Insertion Style Electromagnetic Flow Meters.
Use of grounding rings signiﬁcantly reduces electrical noise and may be necessary for proper operation of electromagnetic ﬂow meters installed in lined or non-conductive pipes.
The size of the grounding rings should always match the meter size (as opposed to the original pipe size) for installation with inline meters.
Standard grounding rings are for use with ANSI Class 150 ﬂanges and are made of 316 Stainless Steel. ANSI Class 300 grounding rings and rings made from Monel and Hastelloy are also available for special applications.
