摘要： An oil level sensor for a vehicle includes a receiver tube oriented upright in the oil pan of the vehicle. A level tube is disposed in the receiver tube and below the level tube is a reference tube. A circuit is electrically connected to the tubes for outputting a signal representative of oil level in the oil pan. As the engine oil level decreases within the level tube, the output of the sensor drops. When the engine oil level is below the bottom of the level tube but higher than the top of the reference tube, the output reaches the lowest value. As the engine oil level continuous decreasing (below the top of the reference tube), the output increases for a first circuit configuration (i.e., level with reference tube), and will stay constant for the second configuration level.

摘要： A method and a device for determining the amount of ink or similar liquid existing in a container are disclosed. A resonance circuit is arranged on the container storing the liquid. A voltage having a preselected frequency is applied to a drive coil located outside of the container to thereby induce a voltage having a preselected frequency in the resonance circuit. The voltage induced in the resonance circuit, in turn, induces a voltage having a preselected frequency in a sense coil also located outside of the container. The amount of liquid in the container is determined in terms of the voltage induced in the sense coil.
