液位量测装置;LIQUID LEVEL MEASURING DEVICE

摘要

本发明提供一种液位量测装置，其包含：一管体，用以容置一液体；一漂浮件，设置在该管体内，该漂浮件随着该管体中液体的液面高度变化而升降；一磁力感测单元，具有至少一磁力感测元件，该磁力感测元件与该漂浮件固定在一起，使得该磁力感测元件与该漂浮件一起浮动；以及复数个磁力源，设置在该管体外，该等磁力源沿着液面高度变化的方向分散设置，以构建出一特定的磁场强度分布，其中该液体的液面高度系根据该磁力感测元件感测到的磁场强度而决定。本发明的液位量测装置具有低成本、有效率且容易布建的优点。; a floating member disposed in the tube, the floating member being risen and fallen as a liquid level of the liquid in the tube varies; a magnetic detecting unit having at least one magnetic detecting element which is fastened to the floating member such that the magnetic detecting element floats along with the floating member; and a plurality of magnetic sources disposed outside the tube, the magnetic sources being distributed at intervals along directions the liquid level varies to establish a specific distribution of magnetic field strength, wherein the liquid level is determined according to magnetic field intensity detected by the magnetic detecting element. The liquid level measuring device of the present invention has many advantages including low cost, high efficiency, and such a device is easily to be disposed.
