Piping made of insulating materials or piping with insulating lining
In such cases, the requirement for the fluid potential equalisation shall be met by two grounding rings
installed before and after the flowmeter. Each grounding ring shall be inserted between two sealing
rings.
The grounding rings are not included among the standard meter accessories
, but they
can be ordered with the product. Regarding chemical stability and resistance with respect to the
measured fluid, the grounding rings shall meet the same criteria as the measuring electrodes.
In the cases of remote meter version, the PE terminal on the meter sensor and the transmitter box shall
be interconnected by a Cu conductor of cross-section 4mm
2
.
This connection shall not serve the purpose of potential equalisation with any other
equipment or devices.
