A fluid control system to control fluid flow within a drainage system is provided that includes a fluid control device configured to couple to an interior wall of a cylindrical structure of the drainage, and a coupling mechanism configured to couple the fluid control device to the interior wall, wherein, while in a resting state, the fluid control device is configured to at least partially cover an aperture of the interior wall. When fluid contacts the fluid control device at a flow rate of at least a flow threshold, the fluid control device is configured to at least partially uncover the aperture of the interior wall. The fluid control device has a spherical shape, wherein a diameter of the fluid control device has a diameter that is greater than or equal to a diameter of the aperture.

A system and method detection of an empty keg is provided. Carbonated beverages from a keg communicates a carbonated alcoholic beverage to a Foam on Beer (FOB) detector. The FOB forms a reservoir and containing a float. Level detection sensors in operative communication with the float identifies the position and movement of the float. An keg's status can thereby be anticipated by float level and speed changes. A the FOB status can thereby operate a touchless tap including a control valve via a tap control board (TCB) that actuates the control valve. A controller in operative communication with the TCB communicates with the control valve, the actuation button and in communication with the level sensor.

A system for collecting and accumulating excess water from one or more in-building sources and delivering it to one or more flushing toilet tanks and possibly also to one or more other in-building consumption devices, such as washing machines or utility faucets. The in-building sources may include any of condensate from an air conditioner, cool water in a hot water supply pipe emerging during initial flow, treated waste water and collected rain- or snow water. At the heart of the disclosed system is an accumulation tank of large capacity, having at least two inlets and at least one outlet. One of the inlets is connected to the main water supply system and includes a valve, configured to let fresh water flow into the main tank whenever the level of the water stored therein falls below a given height. Each outlet is connected to a conduit, conveying water from the accumulation tank to one or more toilet flushing tanks, as their only source, and possibly to other water consumption devices.

A buoyant float including a body having an interior defined in part by a side wall and a bottom extending inward from the side wall. The side wall has an upper edge defining an open top of the body. The float includes a cover sized and shaped for covering the top of the body. The cover attaches to the body to maintain the cover in position relative to the body to cover the open top. The cover has a tubular skirt extending downward and around the upper edge of the body side wall when the cover is in position covering the top of the body. An air pocket is created at an interface between the cover and the body when the float is positioned in liquid to isolate the interface from the liquid and prevent liquid from entering the hollow interior of the body through the interface.

A liquid level control module comprising an elongated tubular housing immersible through a surface of a liquid and into a bulk volume of the liquid, and first, second, and third electrical switches, and first and second floats movable along the tubular housing. The first electrical switch is disposed within a lower portion of the tubular housing, the second electrical switch is disposed within an intermediate portion of the tubular housing, and the third electrical switch is disposed within an upper portion of the tubular housing. Each of the switches has an open state and a closed state. Motion of the first float relative to the first switch changes its state. Motion of the second float relative to the second switch changes its state, and motion of the second float relative to the third switch changes its state. Thus a two-float module may provide three level control signals.

A specific gravity valve, has a floating valve member with a specific gravity that is less than the specific gravity of a first liquid and greater than the specific gravity of a second, heavier liquid. A valve seat is associated with the floating valve member. A valve member retainer retains the floating valve member and permits limited vertical movement of the floating valve member between an open position away from the valve seat and a closed position engaged with the valve seat, such that in the open position, fluid flow through the respective outlet is permitted, and in the closed position, fluid flow through the respective outlet is prevented. The specific gravity valve may be used with a production tank to prevent an unintended draw off of the wrong fluid component in the tank.

A fluid level sensor assembly comprises a sensor mounted to a sensor housing. A carrier extends from the sensor housing in an angled orientation. A float is located within the carrier such that the float may move along a longitudinal axis of the carrier. A fragment is secured to the float, and the sensor detects a location of the fragment as the float moves within the carrier.

A shelf is arranged to pivot about a pivot zone. The shelf has a center of gravity offset from the pivot zone. The shelf has a first angular range about the pivot zone configured to situate a linkage in a valve activation position. The shelf has a second angular range about the pivot zone mechanically configured to situate the linkage in a valve de-activation position. An interaction portion is mechanically configured to urge the shelf from the first angular range to the second angular range by a float moving in a first direction.

A buoyant float including a body having an interior defined in part by a side wall and a bottom extending inward from the side wall. The side wall has an upper edge defining an open top of the body. The float includes a cover sized and shaped for covering the top of the body. The cover attaches to the body to maintain the cover in position relative to the body to cover the open top. The cover has a tubular skirt extending downward and around the upper edge of the body side wall when the cover is in position covering the top of the body. An air pocket is created at an interface between the cover and the body when the float is positioned in liquid to isolate the interface from the liquid and prevent liquid from entering the hollow interior of the body through the interface.

A low profile ice maker/dispenser and water dispenser having a high ice making capacity, for ice nugget manufacture is provided, wherein ice nuggets are metered out of a storage bin via a nugget dispenser outlet, and whereby water is dispensed via a water dispenser outlet. A refrigeration cycle is used, wherein an auger compresses ice on a wall of an evaporator and delivers the ice to the ice bin, breaking it into nuggets along the way. An outer wall of the evaporator is comprised of part of the water reservoir. A baffle in the ice bin facilitates metering of the amount of ice discharged. The system comprises a closed system that enables efficient cleaning of the system.
