  • Visual fluid level indicator using magnetic pins
    Patent number: 6236323
    Abstract: A fluid level indicator (22) indicating the level of a fluid (14) in a chamber (12) having a piston (16) is disclosed. The fluid level indicator (12) has a housing (24) that is positioned adjacent to the chamber (12). A plurality of magnetic pins (28, 38) are moveably disposed within the housing (24). The magnetic pins (28, 38) have a first position and a second position.
