Description
technical field [0001] The invention relates to the technical field of microtube detection, in particular to a capacitive liquid quantitative detection device. Background technique [0002] In measuring instruments, it is often necessary to accurately quantify the reacting liquid to ensure the accuracy of the measurement. The traditional quantitative loop technology usually uses photoelectric technology, quantitative loop technology or syringe pump technology. [0003] The liquid level detection of photoelectric technology is affected by the color of the liquid, pipe wall residue, and pipe wall pollution. The detection accuracy cannot meet the requirements, which will cause missed or wrong judgments. The maintenance cycle is relatively short, increasing maintenance costs and time, and Cannot detect translucent or capillary tubes. [0004] The traditional quantification loop technology is to determine the quantification of the liquid through the volume between the valves. Th...
