Abstract
A device and method for sensing fluid characteristics, including level, temperature, pH and chemistry, comprises a switch affixed to or embedded in a container of a size, shape and density such that said container floats stably in said liquid until a predetermined level is reached; the container tilts so as to operate the switch when the liquid drops below or increases above a predetermined level. The device may contain additional sensors which measure and report other characteristics of the liquid, such as temperature, pH, viscosity, chemistry or biochemistry.
Claims20
An unanchored level sensing device for sensing the level of a liquid in a container and indicating if the level has dropped and/or increased to a predetermined level, comprising a switch affixed to or embedded in a container of a size, shape and density such that said container floats stably in said liquid until said predetermined level is reached, and tilts so as to operate the said switch when said liquid drops below or increases above the said predetermined level.
An unanchored liquid level sensor device for sensing if liquid levels in a container have dropped or increased to a predetermined level, comprising inclinometer means coupled to a switch such that said switch is open when the inclinometer is level and closed when the inclinometer deviates from level by a predetermined amount, said inclinometer and switch being affixed to a container of such size and density that said container floats stably in said liquid until said predetermined level is reached and tilts so as to cause said inclinometer to close said switch when said liquid drops or raises said predetermined level.
