초록 ▼

Digital tilt level sensing probe system comprising a set of multiple capacitor elements in a fluid container arranged along an axis of measurement where each multiple capacitor element represents a discrete level increment in dielectric material fluid to be measured. Individual capacitors in each element are horizontally spaced to reflect a level differential upon tilting of the fluid container from its normal attitude. In the case of a probe for sensing tilting in a single plane, a one-piece body is employed to include integral capacitor elements, mounting pad, connector, custom IC pad, and circuitry molded into such body. Alternative references may be employed for comparison with each capacitor assigned a unique time slot in a switching sequence.

Digital fluid level sensing probe for use in a fluid container comprising a set of capacitors arranged along an axis of measurement where each capacitor represents a discrete level increment in a horizontal plane of dielectric fluid to be measured, each capacitor comprising a pair of individual, electrically, isolated capacitor elements, each individually subject to dielectric fluid which is present at its level and having sensible differential capacitance readable relative to a reference having an intermediate threshold value as to presence or absence of said fluid when addressed in a sequential individual tinge slot for each capacitor, plural individual capacitors at each level being spaced horizontally in columns to sense differentially fluid presence and absence upon tilting of the container from its normal attitude the arrangement of said plural individual capacitors providing memos to compensate for volumetric differentials incident to container tilting which is programmed relative to container configuration for enhanced accuracy of sensing volume indicated by fluid level.
