    Abstract: Embodiments of a system that can detect leaks that occur in seals, and in one example, to seals found in a valve. In one embodiment, the system utilizes sensors that measure fluid properties of a sample volume proximate to the seal. The system can compare data from these measurements with data from a sample of a reference fluid (e.g., ambient air) to indicate the presence of working fluid in the sample volume. This result may indicate problems with the seal, e.g., degradation of the seal that is meant to prohibit the working fluid from migrating out of the valve.

    Abstract: A liquid supply/drain conduit system that is equipped with an inner leakage detector and a liquid process tank that is equipped with such liquid supply/drain conduit system are disclosed. The liquid supply/drain conduit system includes a first conduit for feeding a liquid into an inlet of a first valve of the normal-closed type, a second conduit of T-shape that has a horizontal portion and a vertical portion, the horizontal portion of the second conduit flows a liquid from an outlet of the first valve into a reservoir tank. The second valve of the normal-open type has an inlet and an outlet, the inlet is situated in relation to the first valve in such a way that it receives through a vertical portion of the second conduit a leaked flow of liquid by gravity when the normal-closed first valve failed to close. A liquid detector is further provided for detecting a leaked flow of liquid through the second valve. The leakage detector may optionally include an alarm system to be activated when a leakage flow is detected. The leakage detector may further send a signal to a process controller for alerting a machine operator of the leakage status of the liquid supply/drain conduit system.

    Abstract: A leak detection system and method for fluid operated device includes a backloaded fluidic oscillator having an interaction chamber, a power nozzle at its upstream end coupled to a source of fluid under pressure and an exit throat at its downstream end. The interaction chamber first diverges from the power nozzle and then converges towards the exit throat. A pair of outlet passages are connected to the exit throat; one of the outlet passages is connected to the fluid operated device and the other of the outlet passages is connected to a fixed volume and a vent whereby the backloaded fluidic oscillator oscillates at a rate which is a function of the leakage of the fluid operated device.

    Abstract: A fluid control valve with leak detection and containment features for use in a fluid handling system incorporating one or more flow controlling devices each including: an actuator; a weir valve and associated valve housing; and a pair of spaced apart diaphragms, one of which serves as the closure member for the weir valve and the other providing a secondary seal defining the limits of a containment chamber for at once preventing contamination of the controlled fluid, protecting the actuating mechanism and allowing immediate detection of valve closure failure. A piston member disposed within the chamber is coupled to the two diaphragms, and a fluid detection device is disposed in communication with a sealed containment chamber formed between the two diaphragms. The system includes electronic control apparatus responsive to the detection device and is operative to instantaneously shut down the system in the event of a detected failure.
