ABSTRACT:
An oil mist density gauge for determining the density of oil mist flowing through an oil mist lubrication system. The oil mist density gauge comprises: a gauge body having an oil mist inlet for connecting the density gauge to the oil mist lubrication system and an air outlet for venting air therefrom; a filter device carried by the gauge body and by which oil mist flowing therethrough is separated into oil and oil-free air; and a collection reservoir attached to the gauge body for collecting and measuring oil separated from the oil mist. An eductor device may be provided in the gauge body for drawing oil mist from the oil mist inlet and for introducing air and entrained oil mist into the filter device under a positive pressure.
