A float assembly comprising a float traveling along a rod until making contact with either an upper or a lower adjustable stopper, so that an actuator lever having one or more counterweights in mechanical coupling with a switch, so that the float assembly may respond to the fluid level.

System and method for controlling operation of a vehicle having a fluid reservoir. The system includes one or more fluid level indicators configured to respectively obtain a measured fluid level in the fluid reservoir. A plurality of sensors is operatively connected to the vehicle and configured to respectively obtain one or more parameters. A controller is configured to determine if a fluid level transition between the measured fluid level and a past fluid level is indicated, when there is exactly one fluid level indicator. The controller is configured to identify a reporting state from among a first state, a second state and a third state, based in part on a correlation to a dynamic event and an expected direction for the fluid level transition. A control action is executed by the controller based in part on the reporting state.

A pressure transducer assembly comprises a pressure transducer, a cable, an expandable member, and a vented connector. The cable includes a proximal end, a distal end, and a vent tube. The proximal end is operatively connected to the pressure transducer. The expandable member is operatively connected to the vent tube proximate the distal end. The vented connector is operatively connected to the distal end, and the vented connector is configured and arranged to allow exposure of the vent tube to atmospheric conditions when in a disconnected configuration and to prevent exposure of the vent tube to atmospheric conditions when in a connected configuration. The expandable member accommodates changes in air pressure within the vent tube when the vented connector is in the connected configuration.

A self-cleaning sensor to determine a level of a liquid includes a tube with an interior coating and a plurality of horizontally aligned, electrically isolated, electrical contacts. The self-cleaning sensor includes the plurality of horizontally aligned, electrically isolated, electrical contacts that each terminate in an outer surface of an interior wall of the tube and are electrically connected to one or more electrical devices in a cap residing on the tube. Additionally, the self-cleaning sensor includes a float that is composed of a low density, low dielectric constant material buoyant in one or more liquids to be measured where each horizontal dimension of the float corresponds to each horizontal dimension of the tube.

A multi-probe sender may include a multi-probe having a reed switch arrangement in which reed switches form a level-sensitivity obtaining interval at which a value overlap is prevented in consideration of a resistance-value tolerance range, and having a probe layout forming an intersection interval at which value interference is prevented in consideration of an interval overlap of the reed switches.
