A manifold assembly for a portable leak tester includes a manifold housing defining a fluid inlet, a fluid outlet, a pressure port, and a fluid passage. The fluid passage connects the fluid inlet, the pressure port, and the fluid outlet in fluid communication. A supply control valve is mounted to the manifold housing. The supply control valve is operable to open and close fluid communication through the fluid passage, between the fluid inlet and the fluid outlet. A pressure transducer is coupled to the pressure port. The pressure transducer is operable to sense a fluid pressure in the fluid passage. A manifold controller is mounted to and supported by the manifold housing, and is in communication with the supply control valve and the pressure transducer. The manifold controller includes all software and hardware necessary to control the supply control valve, the pressure transducer, and to communicate with a testing controller. |

1. A portable leak tester comprising:
a moveable cart; a testing controller mounted on the cart; and a manifold assembly in communication with the testing controller, the manifold assembly including:
a manifold housing defining a fluid inlet, a fluid outlet, a pressure port, and a fluid passage connecting the fluid inlet, the pressure port, and the fluid outlet in fluid communication, wherein the pressure port is operatively disposed between the fluid inlet and the fluid outlet;a supply control valve mounted to and supported by the manifold housing, and operable to open and close fluid communication through the fluid passage, between the fluid inlet and the fluid outlet, wherein the supply control valve is operatively disposed between the fluid inlet and the pressure port;a pressure transducer coupled to the pressure port and operable to sense a fluid pressure in the fluid passage at the pressure port, wherein the pressure transducer senses a fluid pressure between the supply control valve and the fluid outlet; anda manifold controller mounted to and supported by the manifold housing, and connected to and in electrical communication with the supply control valve and the pressure transducer, wherein the manifold controller includes all software and hardware necessary to control opening and closing of the supply control valve, operation of the pressure transducer, and to communicate information sensed by the pressure transducer to the testing controller; wherein the testing controller includes software and hardware necessary to control and communicate with the manifold controller. |
