ABSTRACT:
An apparatus for detecting abnormal gains or losses in the amount of liquid lubricant being circulated through a lubrication system of the type having a pressurized side for delivering the lubricant from a main receiving tank to the equipment being lubricated, and an unpressurized drain side for returning the lubricant from the equipment to the receiving tank. The apparatus is located on the drain side of the system, and includes an indicating tank having a cross-sectional area substantially smaller than that of the main receiving tank. The lubricant is returned from the equipment being lubricated to the indicating tank, which is in turn drained into the main receiving tank through a drain line which has a metering valve adjusted to maintain a given operating level in the indicating tank during normal operation of the system. A level indicator generates a warning signal when the liquid level in the indicating tank undergoes an abnormal change from said given operating level.
