Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Referring to Fig. 1, liquid volume measurement of the present invention system comprises electrode pipe fitting 1, electrode detection module 3, control module 5 and transmission module 7 and air pressure aspirator 2.
Please combine referring to Fig. 2, electrode pipe fitting 1 comprises pipeline 11 and is arranged at a plurality of conductive parts of pipeline 11.Air pressure aspirator 2 connects with the endpiece of pipeline 11 and is connected.Each conductive part is connected with electrode detection module 3.
The embodiment one of electrode pipe fitting please combine referring to Fig. 3.
The conductive part of electrode pipe fitting 1 has the multiple form of expression, and wherein a kind of is the pin electrode.At this moment, pipeline 11 is an isolated pipe.A plurality of pin electrodes vertically insert in the sidewall of pipeline 11 with aliging, and each pin electrode is positioned at the madial wall of pipeline 11.Each pin electrode can be connected with electrode detection module 3 through lead.
In the present embodiment, this pin electrode can be metal probe.The volume that can set as required between pipeline 11 per two adjacent needles cellular type electrodes is 1ml.The liquid of 3ml then can pass through the liquid that this liquid volume measurement device is drawn 3ml if desired, and its concrete implementation procedure is asked for an interview as follows.
Please again referring to Fig. 2, the inlet end of pipeline 11 places the vessel 1 that fill liquid, and the endpiece of pipeline 11 is connected with air pressure aspirator 2.This air pressure aspirator 2 can be syringe.The madial wall of the inlet end of pipeline 11 is provided with the first pin electrode 111.Operation air pressure aspirator 2 makes to produce negative pressure in the pipeline 11, thereby the liquid in the vessel 9 is drawn in the pipeline 11.When liquid was full of the volume between the first pin electrode 111 and the 4th pin electrode 115, the liquid of extraction had reached 3ml, at this moment, and shut-down operation air pressure aspirator 2.Because liquid conduction itself, thereby make the pin electrode 111 of winning form closed current return with electrode detection module 3 and the 4th pin electrode 115.Particularly, when the 4th pin electrode 115 rigidly connects when contacting liquid, the impedance in 3 pairs of these loops of electrode detection module has a hurried variation.Electrode detection module 3 can draw the liquid that pipeline 11 has been drawn 3ml according to the hurried variation of this impedance loop.
In the above embodiment of the present invention one, the length of pipeline 11 can or shorten according to the practical situations lengthening, and pipeline 11 can be that flexible pipe also can be a hard tube.According to different applicable cases, can adopt various different-diameters and/or difform pipe fitting.Distance between pipeline 11 every adjacent two conductive parts can be set according to practical situations.Whenever the volume between adjacent two conductive parts can equate, also can be unequal.
