Abstract
An oil reclamation system flow meter for measuring the flow rate of a oil through the system wherein a housing forms a first chamber that leads through a constricted lower outlet into a second chamber and the second chamber. The first chamber also includes an intermediate outlet above the lower outlet and an upper outlet above the intermediate outlet. Both the intermediate and upper outlets flow into a duct that opens into the second chamber at a lower end. Oil flows through an inlet into the first chamber and through the lower outlet when the rate is below an ideal rate range, through both the lower outlet and the intermediate outlet when the rate is within the ideal range and through all three outlets when the rate exceeds the ideal range. A viewing conduit indicates the level of oil inside the first chamber and thereby indicates flow rate.
