External leak detection system to detect a leak in a conduit

Abstract:

A leak detection system configured to be attached on an exterior of a conduit to detect a leak in a non-pressurized conduit. The leak detection system includes a first fluid section and a second fluid section that each includes the same or similar fluid volumes. The first fluid section includes a testing chamber configured be attached to the conduit. With the testing chamber positioned on the conduit, a pressure sensor connected to each of the first and second fluid sections senses a difference in the fluid pressure between the first and second fluid sections to detect a leak.
