Mechanical and electronic combined type liquidometer

The invention relates to the technical field of instruments, in particular to a mechanical electronic combined type liquidometer. To overcome the defects of a floating liquidometer in the prior art, the invention provides a chained buoy liquidometer which can be displayed in a mechanical mode and in an electronic mode and applicable to tank bodies of various modes. According to the technical scheme of the mechanical electronic combined type liquidometer, the liquidometer comprises a main body, a third chain wheel, a magnetic steel seat and a watch hand, the magnetic steel seat is fixedly connected with the upper end of the third chain wheel, and the watch hand is fixedly connected with the lower end of the third chain wheel. The liquidometer is characterized by further comprising a potentiometer. Compared with the prior art, the liquidometer has the advantages that through a chained buoy transmission mechanism, the installation of the liquidometer in the tank bodies in any mode can be satisfied; through the potentiometer, the dual display of the liquidometer data reading ways in a mechanical mode and in an electronic mode can be achieved, and remote monitoring is achieved.
