Abstract: A low water cutoff switch controller features a dual inline package (DIP) in combination with low water cutoff switch processor. The dual inline package (DIP) has DIP switches, each DIP switch configured to set in a respective application type or mode corresponding to a particular water heater model for the low water cutoff switch controller to control, and also configured to provide DIP switch signaling containing information about a respective DIP switch set. The low water cutoff switch processor is configured to respond to the DIP switch signaling, and also configured to respond to corresponding signaling containing information about a sensed water level contained in the particular water heater model being controlled by the low water cutoff switch controller, and provide control signaling containing information to control the operation of the particular water heater model. The low water cutoff switch controller is a single controller that can be used for controlling any one of a plurality of different water heater models and have different voltage applications by setting a respective one of the DIP switches.

Abstract: A spiral heat exchanger features: a cold fluid inlet manifold, a hot fluid inlet manifold and at least one spiral fluid pathway. The cold fluid inlet manifold receives cold fluid and provide cold inlet manifold fluid. The hot fluid inlet manifold receives hot fluid and provide hot inlet manifold fluid. The at least one spiral fluid pathway includes cold spiral pathways configured to receive the cold inlet manifold fluid and provide cold spiral fluid pathway fluid, and hot spiral pathways configured to receive the hot inlet manifold fluid and provide hot spiral fluid pathway fluid. The cold spiral pathways and the hot spiral pathways are configured in relation to one another to exchange heat between the cold spiral pathway fluid and the hot spiral pathway fluid so that the hot spiral fluid pathway fluid warms the cold spiral fluid pathway fluid, and vice versa.

Abstract: A discrete valve flow rate converter is provided to obtain a system flow through a valve in a dynamic hydronic pumping system, e.g., based on signaling containing information about the valve's differential pressure and the valve's hydronic characteristics calibration data. The discrete valve flow rate converter resolves the valve system flow rate directly and accurately with the valve's open position and the corresponding valve differential pressure signals associated therewith. The discrete valve flow rate converter may be applied to all kinds of valves as long as their open position and differential pressure associated with is available, e.g., including implementations for control valve applications, e.g., where the valve open position is controlled automatically and accurately, as well as implementations either for pumping system pressure controls with the flow rate known, such as adaptive hydronic system pressure controls, or as an alternative to sensorless pump monitoring and control.

Abstract: A pump controller has a signal processor that receives signaling about an instant water level AIL of a liquid in a container and generated by a water level transducer during an empty/fill application; and determines corresponding signaling to control a pump during the empty/fill application based upon the signaling received using a liquid level control algorithm that turns ON the pump when the instant water level AIL rises above a maximum empty water level during an empty application, or falls below a maximum fill water level during a fill application; turns OFF the pump when the instant water level AIL falls below a minimum empty water level for the empty application, or rises above a second maximum fill water level during the fill application; controls the pump when the instant water level AIL is in a liquid level region above the minimum empty water level and below a second maximum empty water level for the empty application, or falls below the second maximum fill water level and above a second minimum fill water level during the fill application based upon a respective desired adaptive pressure set point SP* being defined from a respective adaptive liquid level control curve with respect to the instant water level AIL.

Abstract: A contoured check valve disc features a pivot portion and a check valve portion. The check valve portion is attached to the pivot portion, and has two sides, a first side to respond to the fluid flow in a first direction and move the check valve portion away from a fluid opening to the one or more open positions depending on the fluid flow to allow the fluid to flow through the fluid opening, and a second and opposing side to respond to fluid flow in an opposite direction through the fluid opening and move the check valve portion towards the fluid opening to the closed position to seal the fluid opening and stop fluid flow. The check valve portion a near-sloped portion formed nearest to the pivot portion, having a near-sloped contoured surface curving away from the pivot point to a first point of inflection with a first curvature, and a far-sloped portion formed farthest from the pivot portion, having a far-sloped contoured surface curving away from the point of inflection towards a farthest point away from the pivot portion with a second curvature that is less curved or bent than the first curvature, the near-sloped portion and the far-sloped portion combining to form a combined surface having a contoured pressure/force distribution on the first side to respond to the fluid flow and move the check valve portion away from the fluid opening.
