Abstract
A magnetic level indicating system comprises a chamber for fluidic coupling to a process vessel whereby material level in the vessel equalizes with material level in the chamber. A magnet actuated visual indicator is mounted to the chamber for indicating level in the chamber. A float is in the chamber for rising and falling with material level in the chamber. The float comprises a tubular wall defining an interior space. A plurality of elongate magnets are in the interior space. The magnets are parallel to the axis of the tubular wall and are circumferentially spaced along the tubular wall. A circular retainer in the interior space has circumferentially spaced notches receiving the magnets and retaining the magnets along the tubular wall.

A magnetic level indicating system comprising:
- a chamber for fluidic coupling to a process vessel whereby material level in the vessel equalizes with material level in the chamber;
- a magnet actuated visual indicator mounted to the chamber for indicating level in the chamber;
- and
- a float in the chamber for rising and falling with material level in the chamber, the float comprising a tubular wall defining an interior space, a plurality of elongate magnets in the interior space, the magnets being parallel to an axis of the tubular wall and circumferentially spaced along the tubular wall, and a circular retainer in the interior space having circumferentially spaced notches receiving the magnets and retaining the magnets along the tubular wall.
The magnetic level indicating system of claim I retainer ring and with the plurality of elongate magnets sandwiched between the annular rings.
In a magnetic level indicating system including a chamber for fluidic coupling to a process vessel whereby material level in the vessel equalizes with material level in the chamber and a magnet actuated visual indicator mounted to the chamber for indicating level of the material in the chamber, an improved float in the chamber for rising and falling with material level in the chamber, comprising:
- a tubular wall;
- first and second end caps at opposite ends of the tubular wall to define an interior space;
- a plurality of elongate magnets, the magnets being aligned parallel to an axis of the tubular wall and circumferentially spaced along the tubular wall;
- a circular retainer ring in the interior space having circumferentially spaced notches receiving the magnets;
- and
- means for retaining the magnets and the retaining ring in the interior space with the magnets along the tubular wall.
