  • Computer for liquid level measurement
    Patent number: 6529845
    Abstract: A computer (20) adapted to communicate with a measuring apparatus (12) for receiving liquid level measurements and delivering a calibrated fuel quantity output (24) to a readout instrument (14). The computer (20) has an input interface (34) with a first input (22A) for accepting a first liquid level measurement signal from said measuring apparatus (12). A first bias circuit (30A) provides an adjustable offset bias to minimize voltage errors due to input bias current received in the first liquid level measurement signal (26A). Computer(20) also has a calibrating circuit (36) for calibrating the first liquid level measurement signal to provide a calibrated fuel quantity output signal (24) that can be read by readout instrument (14) through output interface (42).

  • Liquid level measurement and fuel transducer using anisotropic magnetoresistance device
    Patent number: 6508119
    Abstract: A fuel quantity transducer (20) suitable for use in a liquid level measurement system (30) uses an AMR device (30) to permit liquid level measurement. A flange (60) is fastened to the inside of a tank (12) and the AMR device (38) on the outside of the tank (12). A support (62) provides a channel shaped piece that is attached to the flange (60) and provides a pivot for a rotor (64). A stop pin (61) is pressed into the support (62) and provides a stop for the rotor (64) at each end of a ninety degree arc. The rotor (64) is a square bar counterbored for a magnet (42) and tapped laterally for a pivot rod. The magnet (42) is placed on the counterbore and retained such that the clearance between the magnet (42) and the flange is small. A float arm (80) is screwed into the axially threaded end of the rotor (64) and secured with a locking jam nut (82).

  • Fuel transmitter for non-electrically invasive liquid level measurement
    Patent number: 6453741
    Abstract: A fuel level transmitter (10) consisting of two magnetic rotors (14, 16) placed on opposite sides of a non-ferrous wall (26) are arranged so that when the first rotor (14) is turned, the second rotor (16) follows due to the magnetic coupling between the two rotors (14, 16). Torque is produced, in part, as a function of the offset of the poles, magnetic strength and the distance between the rotors (14, 16).
