Abstract
Described is an apparatus and a method to accurately determine the gas entrainment characteristics of liquids, such as automatic transmission fluids. The apparatus comprises a liquid reservoir, a conduit having an inlet and an outlet connected to the liquid reservoir so as to form a pressurized recirculating loop for the liquid in the liquid reservoir, a pump for moving the liquid through the conduit, and a means for admitting gas (such as air) into the conduit to aerate the liquid.
