Earthing rings are normally used or suppress electrical interference at the location of installation for magnetic flow meters. Hence, they are offered in pairs and the installation happens upstream or downstream of the flow meter.
The good thing about grounding rings is that their design is meant for installation between the series of magnetic flow meters available in the market and flanges. If you want to reduce the electrical noise emitted in the process, using grounding rings can significantly help you achieve that.
However, one thing you need to keep in mind is always to ensure that the size of the grounding rings matches the meter size for inline meter installation. Installing the magnetic flow meter and grounding it properly helps to provide reliable and accurate measurement performance.
The magnetic flow meter operating principle is derived from Faraday’s Law of Electromagnetic Induction. The law states that you can induce a voltage in a conductor that is moving through a magnetic field.
During installation, ensure that electrical equipment is properly wired and installed per the local electrical code to prevent any hazards to the operating personnel. Also, make sure that both earth grounding connections are well established, and strive to keep the impedance among them quite low.
