Magnetic bearings provide non-contact support for the rotating disk, using magnetic fields to keep the disk in place without metal-to-metal contact. This greatly reduces friction and wear, which helps keep the meter accurate over time. Modern meters use this technology because reliability and long-term accuracy depend on minimizing mechanical wear. Older or obsolete meters typically rely on conventional bearings that wear with use, so they wouldn’t be described as having a magnetic bearing system. The other choices don’t identify this specific feature; they talk about suitability or general wear, not the magnetic, non-contact support that characterizes a modern meter disk.
