Abstract: A method for adaptive calibration of a fuel level indicator of a filling level of a liquid in a tank accompanying operations. A filling level of the liquid is detected with a sensor arrangement. A sensor signal of the arrangement is provided during a movement of the vehicle. In case that the course of the sensor signal is obtained in a respective defined time interval in which the sensor signal is provided several times, a constant value is assumed, an end stop is detected. The respective time intervals at which the end stops were detected and the respective associated constant values are stored. A minimum number of end stop is defined for the tank, and in the case that the minimum number of end stops is reached, a calibration phase is carried out.

Abstract: An apparatus for determining the fluid level of a container, such as an accumulator, may include both a remote quantity indicator and a direct quantity indicator. The remote quantity indicator may include a remote dial at the end of a flexible cable or an electrical signal receiver receiving an electrical signal from a rotary variable differential transformer (RVDT), such as a potentiometer. The RVDT type of indicator may include an electrical connector on the accumulator to attach an electrical cable to carry the quantity level signal. The direct quantity indicator may include a dial directly mounted on the accumulator. The remote/direct quantity indicators may include, for example, one of the following three combinations: 1) a dial directly on the accumulator and a remote dial at the end of a flexible cable; 2) an RVDT output and a dial directly on the accumulator; and 3) an RVDT output on an accumulator, a remote dial at the end of a flexible cable and a dial directly on the accumulator.

Abstract: A remote visual liquid quantity indicator comprises a flexible cable within a flexible outer sleeve and allows a user to remotely determine the level of a liquid in a container, such as an accumulator without the need for electrical power or a direct line of sight to the container. The flexible cable may be coupled between a reservoir sweeper of the accumulator and an indicator. Changes in the fluid level of the accumulator may provide a linear movement to the flexible cable, which in turn provides a change to the measurement reading of the indicator. The flexible cable/outer sleeve allows for the complex routing scenarios necessary in the congested spaces surrounding aircraft accumulators.

A detecting device is carried via the buoy for detecting at least one environmental characteristic and for producing at least one signal representative of the at least one environmental characteristic. A signal wire is electrically connected with the detecting device. The signal wire includes a helical section for automatically adjusting a distance between its two ends according to the position of the buoy. A monitor device is electrically connected with the signal wire.

Abstract: A magnetically activated float switch apparatus is disclosed for opening and closing an electrical circuit in response to a predetermined change in the level of a liquid. The apparatus includes a float element having an interior chamber. There is a capsule mounted within the chamber. A permanent magnet is mounted in the capsule and is slidable between first and second positions therein. A switch is mounted in the chamber adjacent to the capsule and is electrically connected to the electrical circuit. The switch is responsive to the permanent magnet in the first position for maintaining a first state and is responsive to a permanent magnet in the second position for maintaining an opposite second state. One of the states is open and the other is closed. The float element is suspended by a cable in an upright condition when the liquid is below a known level such that the magnet is in the first position and the switch is in the first state.

Abstract: A float switch for sensing a liquid level and switching between "on" and "off" states in response to the same. Overall, the device is carried within a hollow housing, with its movement restrained by the tethering action of a power cord. "Snap action" switching is achieved by the interaction between an actuator having camming surfaces formed on its exterior, and a spring-loaded switch mechanism. The switch mechanism includes a thin, flexible E-shaped snap member, having two legs bowed to form a leaf spring and having a bearing point located on the central leg. The actuator is carried in a tube within the housing and the switch mechanism is positioned adjacent the actuator's path of travel, so that a camming surface of the actuator can make contact with the bearing point. As the water level rises, an increasing proportion of the actuator's weight is carried by the bearing point, until the vertical component of the actuator weight exceeds the spring resistance of the snap member.

Abstract: A float switch assembly for selectively energizing and deenergizing a fluid pump or other electronic equipment responsive to the rise and fall of a fluid level within a reservoir and a method and manufacturing or assembling the float switch assembly. The assembly includes a hollow tube having an open end wherein a mercury tilt switch is fixed. A plurality of conductors covered with a non-conductive material extend within the tube open end and are connected to the switch so that a current path may be provided between the conductors responsive to the angle of the switch. Ridges are provided on the outer surface of the tube near the open end and, a float bulb is provided substantially surrounding the tube below the ridges and sealingly connected upon the ridges. A potting epoxy compound surrounds the switch and the conductors within the tube so that electrical contact with a fluid through the open end is prevented. A cap is placed on the tube open end and is locked into place.

Abstract: A float assembly for use in tanks, sumps or other liquid-containing vessels includes an elongated, upright, extruded support which maintains individual float switches at preselected heights. The support includes upright, elongated, recess-defining walls with a pair of flat, spaced, parallel sidewall portions that are configured to grippingly engage an outer, deformable insulative covering of a cord connected to the float switch. The cord may be grasped and pulled to an appropriate height, and is thereafter secured by the sidewall portions without the use of tools, fasteners or other components. In preferred forms, the recess-defining walls have a transverse, generally U-shaped configuration with an internal passageway for housing an upper portion of the cord between the float switch and an overlying junction box.

Abstract: A mercury activated float switch comprises a base member, a resilient fulcrum, desirably comprising an aperture in a resilient sheet, supported on said base member and at least two flexible electrical current carrying conductors supported for pivotal movement about the resilient fulcrum. A float member has associated therewith a switch assembly in which the electrical conductors terminate as spaced apart contacts. An angled mercury-containing race within the float member communicates with the switch assembly. As the liquid level changes, the float member pivots about the resilient fulcrum between first and second positions. The mercury in the race occupies the end of the race remote from the switch assembly when the float member is in its first position and flows into the switch assembly to bridge the space between the contacts when the float member is in its second position.

Abstract: A device designed to replace the conventional automotive dipstick wherein the level of oil in an automotive crankcase is continually monitored by means of a direct readout on a visual gauge mounted on a vehicle dashboard or other convenient location within the automotive passenger compartment. The device consists of a length of cylindrical tubing threadably adjustable within a cap to predetermine its overall length as required by the specific oil reservoir, a float mechanism attached to the bottom end of the cylinder tubing, with the float being mechanically and electrically connected to a float resistor. The float lowers as the oil in the crankcase is depleted so as to register a corresponding reading on the visual gauge in the automotive passenger compartment.
