Kind Code:
A
Abstract:
Magnetic gauge circuitry in which a magnetic gauge has a plurality of coils and has indicating means responsive to current in the coils is provided with switching means for interrupting the current flowing to the coils. The gauge may be constructed to maintain its reading even though its input current has been interrupted. Current interruption to the gauge occurs when the switching means undergoes accelerations or decelerations or a change in its orientation with respect to the earth's gravitational field. The magnetic gauge circuitry is particularly advantageous when used in the measurement of the liquid level in a fuel tank of a motor vehicle.
