Lubricating fluid is continuously sampled from the return line (Fig. 1) and fed by a pump 7 to a cartridge membrane filter 9. The membrane filters out particles from the fluid and discharges the fluid through a volume meter 13 back to the fluid reservoir 1. The cartridge can be removed from the apparatus for analysis. Apparatus also includes a heater 8, pressure gauge 17, pressure-operated by-pass valve 18 and valves 10, 12 operable to by-pass the filter 9, e.g. during filter replacement, and to obtain a fluid sample at 16. <IMAGE> |
