Abstract
A system and method for detecting leaks in an enclosure having a port and intended to prevent liquid material from exchanging into or out of the enclosure. A vacuum pump is coupled to the port and the enclosure is subjected to an applied vacuum pressure. Measurements of the mass and pressure within the enclosure while subject to the applied vacuum pressure are compared to expected values to detect a leak. In some embodiments, the physical arrangement of a valve of the enclosure is measured and compared to expected values to detect a leak.
