A quick connect/disconnect system includes a male connector and a female connector. The male connector includes a first body having a fixed male protrusion and a first rotating ring assembly rotatably connected to the first body. The female connector includes a first coupling channel including a mouth configured to receive the fixed male protrusion and extending from the mouth toward a seat portion, a shuttle movable within the first coupling channel and including a flange configured to form a seal with the seat portion, and an extending portion extending within the first coupling channel and a biasing member configured to bias the flange into sealing contact with the seat portion such that rotation of the first rotating ring assembly in a first direction forces the fixed male protrusion to move axially into contact with the extending portion thereby moving the shuttle to force the flange away from the seat portion.

A quick connect/disconnect system including a male component having a first fluid channel, a first male coupling portion, and a second male coupling portion. A first ring assembly is supported by the male body and extends about the second male coupling portion and includes a male mating feature on an internal surface of the ring assembly. A female component includes a first female coupling portion, a second female coupling portion, and a second fluid channel sized to receive the second male coupling portion. A female mating feature is configured to rotatably engage the male mating feature, such that when the second female coupling portion is coupled with the second male coupling portion and the female mating feature is mated with the male mating feature, the first fluid channel is in fluid communication with the second fluid channel.

A quick connect/disconnect system male component includes a first body and a ring assembly. The first body defines a fluid channel therethrough. The first body includes a first coupling portion at a first end portion and a second coupling portion at a second end portion. The first coupling portion is configured to couple with a fluid conduit and the second coupling portion configured to couple with a female quick connect/disconnect system component. The ring assembly is supported by the first body. The ring assembly extends about the second coupling portion and includes a first mating feature on an internal surface of the ring assembly configured to rotatably engage a second mating feature on an external surface of the female quick connect/disconnect system component.

A magnet assembly (200) is provided that comprises a magnet keeper (204) configured to hold at least one magnet (202). The bracket (208) is configured to receive the magnet keeper (204) and also configured to be attachable to a flowmeter (5) sensor assembly (10). A first surface (216) is formed on the magnet keeper (204), and a second surface (218) is formed on the bracket (208), wherein the first and second surfaces (216, 218) are configured to mate so to provide a radial alignment of the magnet keeper (204) that is within a predefined radial tolerance range.

A coupling which can enhance safety will be provided, when the coupling, a hose, and the like are exposed to high pressure for some reasons or other while in use, by leaking the high pressure fluid to the outside to open a sealing portion of the coupling at a stage where the coupling condition between the couplings is maintained, and decreases the pressure. Further, the coupling can warn the operator or the like of the abnormality by ejecting a fluid from a leak path or a fluid ejection port.

A coupling has an engagement face of a engagement hook which is set at an angle in a range where the engagement face is still inclined at a positive angle to be maintained a coupling state of the couplings, even if a fluid leaks by opening the sealing portion of the couplings at a state where the coupling state is maintained or even if a hose or the like fitted to the coupling is burst when the coupling, the hose, etc., are applied the high pressure for some reason or other while in use.
