Apparatuses, systems, and methods are disclosed for fluid flow control. A container is shaped to receive a liquid. An inlet is configured to allow the liquid to enter the container. An outlet is configured to allow the liquid to exit the container. A float is disposed within the container. A valve is actuated based on a position of the float within the container to open the valve at a first liquid level within the container and to close the valve at a different liquid level within the container.

The present invention relates to the fluid discharge device of a fluid transfer pipe, and to a technology which alters the sectional area of a discharge hole in proportion to the increase or decrease in fluid discharge flow per unit of time so as to maintain a relatively uniform fluid discharge rate from the discharge hole.

A swimming pool leveling system includes a bracket extending from a first end to a second end, the bracket having openings; a float valve having a body with a float positioned within an interior of the body, the float valve engaged with the bracket via an adjustment device; a pressure reducing valve engaged with the body and to receive a water source; and a base having a base body with an enclosed interior accessible via an opening, the enclosed interior configured to receive a weight, the base having knobs protruding from an end to engage with the openings to secure the base to the bracket; the base is to rest on a surface such that the bracket extends the float valve into a pool; and the float valve to allow filling of the pool to a desired height.

The invention relates to autonomous membrane liquid purification devices with the possibility of recirculation and/or desalination of liquid, mainly water from various sources for domestic and/or drinking water supply and is intended for use in domestic conditions, public institutions, in suburban and garden areas. A membrane liquid purification device consisting of a liquid tank, a liquid withdrawal means, a pressure increasing means, a liquid purification unit, a purified liquid line and a drainage line, characterized in that it is made with the possibility of taking liquid from preferably the surface layer of liquid in a liquid tank and automatically stopping the liquid purification process when the liquid level in the liquid tank reaches a set value and/or after the required volume of liquid is purified.

A dump valve system controls the level of a liquid inside a vessel that includes a liquid discharge. The dump valve system includes an automatic dump valve connected downstream from the liquid discharge and configured to adjust the flow rate of the liquid through the liquid discharge, a float inside the vessel, a float arm connected to the float, and an inclinometer attached to the float arm and configured to output an angular disposition signal representative of the angular disposition of the float arm. The dump valve system can also include a flow meter configured to measure the flow rate of liquids discharged from the automatic dump valve and output a flow rate signal representative of the measured flow rate. A control module is configured to adjust the operation of the automatic dump valve in response to the flow rate signal and the angular disposition signal.

Apparatuses, systems, and methods are disclosed for fluid flow control. A container is shaped to receive a liquid. The container has a configurable width. An inlet is configured to allow the liquid to enter the container. A valve is actuated to open at a first liquid level within the container and to close at a different liquid level within the container. An amount of time that the valve is opened is determined based on the width of the container.

What is presented is a fluid fitting used in a facility that has a plurality of surfaces and a source of fluid pressure. The fluid fitting comprises a mounting component, a conduit adapter, a port, and a fluid management device. The mounting component makes the fluid fitting mountable on the external side of the surface. The conduit adapter is connectable to the fluid handling conduit on the internal side of the surface. The port has a flow path to the conduit adapter that enables a fluid connection between the conduit adapter and the port. The fluid management device is permanently incorporated in the flow path such that the fluid management device is permanently connected to the port at the fluid dispensing point.
