Warren Industrial designed and built a Vacuum/ Mass Flow Test Stand for a local automotive parts manufacturer. A bar code on the part needing testing would be scanned, and HMI would indicate to operator which test plugs to use. Operator then engages test. First the vacuum is tested, checking for leaks and if the leak rate is passible the mass flow test then begins. If the mass flow test passes, the operator is informed. A failed part will cause the plugs to stay expanded and forcing an operator to press a release button and putting a print out label indicating the failure the part had.
