に連通した絶縁性の揚水管を上下方向に配置し、
その外表面に互いに絶縁され、相対向する一対の
電極を設け、この一対の電極で揚水管内の液量に
応じて連続的に容量が変化するコンデンサを形成
するとともに、前記一対の電極を、容量に応じて
出力するパルス幅が変化する発振回路のコンデン
サとして用い、前記発振回路からの出力信号に基
づいて貯留液量を検知しうるようにしたことを特
徴とする容器内の液量検出装置。 An insulating water pump whose lower end communicates with the bottom of the container is arranged vertically on the side of the metal container,
A pair of mutually insulated and opposing electrodes is provided on the outer surface of the pump, and the pair of electrodes forms a capacitor whose capacitance changes continuously according to the amount of liquid in the pumping pipe. A device for detecting the amount of liquid in a container, characterized in that the device is used as a capacitor of an oscillation circuit whose output pulse width changes according to the amount of the liquid, and the amount of stored liquid can be detected based on the output signal from the oscillation circuit.
