C: send pulse electrical signal to linear electric motors by intelligent display control module, until non-contact capacitance liquid level meter and liquid level are at grade;
D: the pulse electrical signal sum that single-chip microcomputer sends according to step C and the non-contact capacitance liquid level meter that the distance that each pulse electrical signal linear stepping motor advances calculates advance total distance, this total distance of advancing is liquid level a, and the distance that linear stepping motor often receives a pulse electrical signal advance is all identical;
E: when liquid level changes, the signal that non-contact capacitance liquid level meter collects liquid level change is sent to single-chip microcomputer, and motion of melt surface followed by Single-chip Controlling linear electric motors;
F: the liquid level changing value that the liquid level a in step D adds in step e is now liquid level value b by single-chip microcomputer;
H: liquid level value b is sent to display by single-chip microcomputer.
In the utility model, non-contact capacitance liquid level meter can adjust automatically along with the height change of liquid level, therefore, the installation site again adjusting liquid level sensor is not needed after liquid level change, and owing to have employed the liquid level sensor of non-invasive, be installed on external container very convenient, do not affect stored liquor quality.
