the utility model discloses a linear proportional liquid level meter with the patent number of ZL201721513145.7, which solves the problems that a magnetic turning plate displays the liquid level measurement in a wide range tank, the 1:1 proportional relation between a floating top stroke and a magnetic heavy hammer stroke is changed into the linear n:1 proportional relation, and the height of a liquid level display and magnetic sensor remote transmission device is reduced to the optimal visual range of a human body by arranging the number of pulleys according to the linear proportion according to the height of a closed liquid storage tank. In order to adapt to the visual range, the display panel is only 1 m-1.5 m high, but the measured liquid level is between 6 m-30 m, and the ratio of the height of the scale to the height of the liquid level is not 1:1 but 1: 4, 6, 10) XN.
The inventor has a patent number ZL201721513145.7 linear proportional liquid level meter, and each magnetic turnover plate accounts for 60mm of a liquid level display value of a scale by 10 mm. Assuming that the ratio is 1: 12, the magnetic turning plate occupies 120mm of liquid level display value of the liquid level of the scale, and the defect is more serious when the ratio is increased. Two bits behind the decimal point displayed by the liquid level can not be distinguished, and the accuracy is low.
