Abstract: A well management system provides Internet-enabled monitoring, configuration, and control of a well system that may include a pump and a pressure tank. A controller is operatively coupled to the pump. The controller controls the pump based on pressure readings from a pressure sensor to maintain a configured pressure range within the system. The controller can communicate with a management system via a communications network. The management system is further in communication with one or more client devices, which may be associated with a homeowner, a service provider, a manufacturer, or the like. Via the management system, the client devices can receive information from the controller and send commands to the controller.

Abstract: Disclosed is an expansion tank having an internal cavity separated by a flexible diaphragm to form an upper pressurized gas portion and a lower pressurized fluid portion, and an indicator positioned at an upper part of the expansion tank in communication with the contents of the upper pressurized gas portion. The indicator is configured so as to display a first color if the operating conditions are normal in the pressurized gas portion, and a second color if the amount of moisture detected in the pressurized gas portion greater than or equal to a predetermined amount. Further disclosed is a method for detecting whether there is an excessive amount of moisture in a pressurized gas portion of an expansion tank by allowing pressurized gas from the pressurized gas portion to come into contact with the indicator, and viewing the color displayed by the indicator. As such, the tank can be simply visually inspected to determine whether there is a potential failure in the tank.

Abstract: An absorber for use in a fluid delivery system is disclosed which includes a housing defining an interior chamber, a connective fitting extending from the housing in fluid communication with the interior chamber for connecting the housing to the fluid delivery system, and at least one gas-filled bladder or cell disposed within the interior chamber of the housing to accommodate changes in fluid characteristics, such as, for example, pressure and volume, within the fluid delivery system, the gas-filled bladder or cell having a predetermined pre-charge pressure and a multi-layered flexible polymeric shell including a plurality of successive relatively thin polymeric shell layers to inhibit the formation of leak paths through the shell in the event that a single shell layer fails.

Abstract: Disclosed is an absorber system for absorbing pressure shocks and fluid volume shocks in a fluid system. In particular, the absorber system includes a housing with a joint for insertion within a fluid system, wherein the housing interior is in fluid communication with fluid in the fluid system. As such, when a pressure and/or fluid volume shock is developed within the fluid system, fluid is forced into the housing via the joint. A membrane is disposed within the housing in such a way that the fluid impacts the membrane which, in response, flexes to absorb and control the pressure and/or fluid volume shock within the fluid system. The absorber system, thus, controls pressure and/or fluid volume shock within a system and can prevent water hammer and other problems which can result from the development of pressure and/or fluid volume shock.
