Abstract
One or more systems are disclosed for leak detection for a pump that include a reservoir having a chamber with an inlet and an outlet. The inlet is configured to couple to an exhaust of a pump and the reservoir is configured to create a vortex flow therein. An optical sensor is positioned at a bottom of the reservoir with a detecting portion of the optical sensor extending into the chamber. The vortex flow causes one or more liquids to settle at the bottom of the reservoir on the optical sensor. The one or more liquids are indicative of a leak and the optical sensor is configured to detect the one or more liquids.
