Universal fuel sensor for liquid crystal instrument and mechanical instrument

The invention discloses a general fuel oil sensor for a liquid crystal instrument and a mechanical meter, which comprises a columnar sensor body, a mounting cover plate is arranged at the top of the sensor body, a cable joint is arranged on the mounting cover plate, an electrode fixing seat is arranged on the sensor body, and a positive electrode connecting terminal and a negative electrode connecting terminal are arranged on the electrode fixing seat. A rotatable sliding disc is arranged on the electrode fixing seat, a floater connecting rod is arranged on the outer wall of the sliding disc, a floater is arranged at the tail end of the floater connecting rod, and when the floater ascends or descends, current flowing between the positive electrode connecting terminal and the negative electrode connecting terminal is in linear relation with the height of a floater rocker arm of the floater. In a two-line state, the universal fuel sensor for the liquid crystal instrument and the mechanical instrument can enable
