  • Fluid level sensor
    Patent number: 5000044
    Abstract: A pivoted float contains a solid-state inclinometer which produces sensitive electrical output responsive to angular displacement of the float from the direction of gravity. The float is capable of resolving very small changes in liquid level in a vessel, and thereby indicating or warning of small leaks from the vessel.
    Type: Grant
    Filed: June 20, 1986
    Date of Patent: March 19, 1991
    Inventors: Dennis M. Duffy, Gary G. Small
  • Fluid level sensor
    Patent number: 4610165
    Abstract: A fluid level sensor comprising a pivoted float which contains a solid-state inclinometer that produces sensitive electrical output signal responsive to angular displacement of the float from the direction of gravity. The float is capable of resolving very small changes in liquid level in a vessel, and thereby indicating or warning of small leaks from the vessel. A reference inclinometer may also be provided for producing a reference signal to compensate for fluid level signal errors caused by motion of the vessel.
