Abstract
Official abstract text for this publication.
A system for determining the location of a movable element within a container is provided in which a linear variable differential transformer (“LVDT”) is formed with the container and the movable element therein. The LVDT includes a coil assembly including a primary or excitation winding, a secondary or output winding, and a movable element or core that is magnetically permeable. Measurement of an output signals allows for precise determination of the movable element location relative to the container. The system can be utilized to determine fluid volumes in accumulators used for controlling subsea equipment by monitoring the location of a movable element, e.g., a piston, within a hydraulic fluid accumulator.
First claim
Opening claim text (preview).
What is claimed is: 1 . An accumulator comprising: a housing; a movable element disposed in the housing and comprising a magnetically permeable material; and a measurement system, comprising: an excitation winding excitable by an excitation signal from a power source; and output windings adapted to be inductively coupled to the excitation winding and the movable element, and adapted to produce output signals upon excitation of the excitation winding.…
