    摘要: A liquid level detecting device and a fuel tank structure are obtained that do not require provision of plural, independent detection electrodes. A liquid level detecting device 40 has a pair of electrode plates (42, 44), and has a first detection electrode (70A) that detects electrostatic capacitance between the pair of electrode plates, and a variable structure (60) that can vary a surface area of an overlapping region of the pair of electrode plates (42, 44) and can switch to a second detection electrode (70B) by changing the surface area by a predetermined amount with respect to the first detection electrode (70A).

    摘要: PROBLEM TO BE SOLVED: To provide an electronic circuit of a liquid level measuring probe which is hardly affected by heat.
    SOLUTION: A capacitance type liquid level measuring probe 10 includes two concentric metal tubes 12, 14 which are extended downward into an oil tank. The concentric metal tubes 12, 14 form two plates of a capacitor. The probe 10 measures an oil level in the tank during a test of a jet engine by detecting a change of the electric capacity between the two concentric metal tubes 12, 14, wherein the change of the capacitance is generated by a level change of the oil. A measuring circuit 30 includes a temperature compensation resistor and a temperature stabilization detector. A measuring electronic circuit package is stored separately, and connected to the probe 10 through a cable 44, and thereby a circuit 30 can be arranged on a position separated from a hot environment in which the probe 10 is operated.

    摘要: PROBLEM TO BE SOLVED: To provide a liquid tank accurately measuring a volume by reducing an effect of disturbance on a measurement result, and a fuel cell using the same.SOLUTION: One surface of a liquid container section is configured of a detection element formed by sequentially stacking a first substrate to a fourth substrate, each consisting of a printed circuit board. A pair of detection electrodes 12A and 12B are arranged on the surface of the first substrate, and a floating capacitance is detected by directly or indirectly bringing the pair of detection electrodes 12A and 12B into contact with a liquid fuel in the liquid container section. A second substrate having a shield electrode 22 is disposed on the back surface of the first substrate. Even when a hand or the like is put close to the detection element, the resulting floating capacitance is prevented from being sensed by the detection electrodes 12A and 12B.

    摘要: PROBLEM TO BE SOLVED: To highly accurately measure the water level of a liquid stored in a liquid tank.
    SOLUTION: The water level L
    0 of the liquid is read from a water level gauge mounted to the liquid tank (S1). A filter value FLT is computed by applying a filter having a time constant greater than one second to the water level L
    0 (S2). When the filter value FLT is smaller than a minimum value Min, the minimum value Min is sequentially updated by the filter value FLT (S3 and S4). The minimum value Min is outputted as a final water level L (S5). Since a minimum value utilizing characteristics of liquid level variations is adapted as the final water level L even if the water level L
    0 varies due to oscillations of the liquid level to make it difficult to receive the effects of liquid oscillations in this way, it is possible to improve accuracy in water level measurement.

    解决方案:从安装在液罐(S1)上的水位计读取液体的水位L 0 。 通过将具有大于1秒的时间常数的滤波器应用于水位L 0 (S2)来计算滤波器值FLT。 当滤波器值FLT小于最小值Min时,通过滤波器值FLT顺序更新最小值Min(S3和S4)。 输出最小值Min作为最终水位L(S5)。 由于利用液位变化特性的最小值作为最终水位L,即使水位L 0 由于液位的振荡而变化,使得难以接收液体的影响 以这种方式振荡,可以提高水位测量的精度。 版权所有(C)2008,JPO&INPIT
