Abstract: By implementing an oil monitoring in a rotary meter, the meter can check the oil level, condition and/or both level and condition and report any issues detected such as out-of-limit low oil condition, contamination, etc. The function can trigger a preventative maintenance on the rotary gas meter with a view to improving its longevity. Oil level monitoring may be signalled using sensors such as switches. Oil colour, clarity, aeration and foaming, corrosion, varnish, wear debris, or other quality monitoring may be signalled using sensors such as spectrometers. A rotary meter may be configured with one or more such sensors for (multi-)parameter monitoring and the one or more sensors positioned in respective locations such as at an oil reservoir.
