Abstract
A dial assembly with magnetic calibration feature adapted for use as part of a gauge assembly for measuring fluid levels in cryogenic applications is disclosed. The dial assembly includes a base, a pivot pin extending from the base, a pointer assembly pivotally mounted on the pivot pin, and a calibration magnet with adjustment feature. The pointer assembly includes a pointer coupled with a pointer magnet. The calibration magnet with adjustment feature is magnetically coupled to the pointer magnet and adapted to adjust a position of the pointer magnet and therefore the pointer relative to volume indicia on a dial face of the dial assembly. In operation, a movement of the calibration magnet induces a movement in the pointer magnet. The adjustment feature is coupled to the calibration magnet such that it is manipulatable even when the dial assembly is mounted on a gauge head of a gauge assembly installed on a vessel. Further, the dial assembly preferably also includes a pivot pin adjustment feature for repositioning the pointer assembly relative to the dial face.
