The invention discloses an isolated servo liquid level measurement device. The isolated servo liquid level measurement device is characterized in that the isolated servo liquid level measurement device comprises a servo liquid level gauge, a vertical isolation protection tube with an opening arranged only at the top end, a magnetic floating ball sheathed on the vertical isolation protection tube, and an iron gravity ball, wherein the servo liquid level gauge comprises a servo motor, a wheel hub assembly provided with an electromagnetic sensor, an encoder and a microprocessor; the wheel drum assembly comprises an inner hub and an outer hub; the tube body of the vertical isolation protection tube except for the top end is mounted in a storage tank together with the magnetic floating ball; the magnetic floating ball floats on the surface of a liquid in the storage tank, and goes up or goes down with the liquid level change in the storage tank; the iron gravity ball is hung on a measurement steel wire wound on the outer hub, and is placed in the cavity of the protection tube; and the magnetic floating ball and the iron gravity ball can generate magnetic action. The isolated servo liquid level measurement device is simple in structure, easy in installation, and convenient in daily maintenance of the servo liquid level gauge; and the servo liquid level gauge can be maintained only by pulling the iron gravity ball out of the protection tube.
Description
Technical field [0001] The invention relates to a servo liquid level measuring device which can be applied in high pressure, vacuum or corrosive liquid and explosive environment. Background technique [0002] With the development of economy and the improvement of industrial automation, people have higher and higher requirements for the storage and management of fuel in industrial raw materials. Some toxic, hazardous or flammable and explosive liquids require special tanks for storage. The technical requirements for these storage containers are very high, not only requiring the container to have strict sealing properties, but also requiring high pressure resistance, corrosion resistance and other characteristics. Faced with such harsh technical conditions, liquid metering in special containers has become a key issue. At present, most of the servo-type liquid level measuring devices on the market appear powerless when faced with such a harsh environment. Even if some servo-type ...
