  • Side arm fluid level gauge with spaced-apart sensors for density error compensation
    Patent number: 4711117
    Abstract: In fluid level measurement apparatus a pressure vessel is tapped into a fluid container the fluid level in which is to be measured such that fluid level in the vessel is representative of fluid level in the container. A plurality of fluid detecting sensors are mounted in the vessel with unequal spacing to compensate for level errors due to density differences between the fluid in the vessel and container.
