Description
Technical field
The present invention relates to a kind of measurement mechanism, particularly relate to a kind of liquid volume measuring device.
Background technology
Along with the development of chemical analysis technology, all trades and professions require more and more higher to the degree of accuracy of liquid volume measurement.At present, although can measure by surveying instruments such as graduated cylinder, transfer pipet, syringe pump, Ultrasonic Liquid Level Indicators the volume of liquid, the degree of accuracy that has in these methods is not high.In addition, because existing to expand with heat and contract with cold, liquid has the similar compatibility characteristic between characteristic, solvent and the container, so that the degree of accuracy of measuring further reduces.The most important thing is that above traditional measurement instrument can't accurately immediately be measured the dynamic liquid volume.
Summary of the invention
Technical matters to be solved by this invention is that a kind of accurate, convenient and practical a kind of liquid volume measuring device of measuring is provided.
For solving above technical matters, technical scheme of the present invention is: a kind of liquid volume measuring device, comprise measuring vessel, with the electrode of described measuring vessel close contact, with volume sensor and liquid volume conversion module that described electrode is connected successively, described liquid volume conversion module can be single-chip microcomputer.
As improvement of the present invention, comprise that also described fixture of the spring comprises interconnective spring and spring block for holding the measurement passage that carries described measuring vessel and the fixture of the spring of being located in the described measurement passage.In addition, also comprise bonnet, described bonnet props up described spring.
Further improve as the present invention, also comprise interconnective temperature sensor and thermostat.Wherein, described measuring vessel is for measuring test tube, and described electrode is sheet metal electrode or electrode coating.
As preferred version of the present invention: described sheet metal electrode is arranged at the outer wall of described measurement test tube, and described electrode coating then is coated on the inwall of described measurement test tube, and described sheet metal electrode is with half of described measurement test tube outer wall or whole parcels.
By implement the present invention desirable following useful technique effect: the present invention includes electrode, electrode links to each other with volume sensor.Measuring test tube with one tightly is stuck in the measurement passage, then in vitro inject a certain amount of liquid in described measurement, described volume sensor can be by sheet metal electrode in the described measurement passage or the signal of electrical properties transmission that measure coated electrode in vitro to liquid volume conversion module single-chip microcomputer for example, can learn the in vitro volume size of liquid after processing through single-chip microcomputer.
In the measurement passage that temperature sensor will record be described measurement in vitro the temperature data of liquid pass to thermostat, thermostat will transmit the temperature data that comes and design temperature and heat up or cooling determining after relatively.Can reach the purpose of measuring the interior temperature constant of passage (measuring in vitro liquid) by such control mode, thereby reduce to greatest extent the liquid impact of characteristic on its cubing degree of accuracy of expanding with heat and contract with cold.
Described fixture of the spring comprises interconnective spring and spring block, and described spring block can be fixed in the test channel firmly with measuring test tube, rocks measurement is exerted an influence to avoid measuring test tube, thereby improve the degree of accuracy of measuring.This spring block can also be attached on the metal electrode tightly with measuring test tube, so that metal electrode can more accurately and timely obtain the liquid level data of testing liquid, thereby realization is to the kinetic measurement of liquid volume.
Described measurement test tube not only can separate testing liquid and metal electrode, stops the similar characteristic that mixes of liquid to measuring accurate impact, can also avoid entering measurement in vitro on the impact of measuring accuracy because of impurity.
The sheet metal electrode is with half of described measurement test tube outer wall or whole parcels, and the present invention requires can satisfy basic need to the measurement of liquid volume when carrying out half parcel, and the cubing accuracy further improves when all wrapping up.When electrode coating then being coated on the inwall of described measurement test tube, can obtain maximum precision of measurement.
Obviously, the degree of accuracy of liquid volume measurement can be greatly improved by implementing the present invention, the kinetic measurement to liquid volume can also be realized.
