There is horizontal scale line, rectangular tube can store more liquid, can subtract using the first short tube and the second short tube of this structure
The viscous bubble of education and correction for juvenile offenders cavity wall, improves the accuracy of measurement.
Working principle are as follows: before measurement, horizontal ruler is placed in tested plane, observing in the first transverse tube, in the second transverse tube is
It is no there are viscous bubble, in the first transverse tube with the presence or absence of in the short tube at viscous water section and scale with the presence or absence of viscous
Bubble, if above-mentioned three kinds of situations all do not have, level measurement is accurate at this time.Measurement degree method is as follows: reading respectively
Scale value at the short tube at ruler both ends out, the difference between the two are exactly the difference in height of tested plane straight line where ruler.Work as the two
Degree is identical, then it represents that the place straight horizontal.When there are viscous bubble or bubbles in lumen constantly, then carry out operating as follows:
Ruler slowly at the uniform velocity is switched to place vertically by laying flat, analysis is it is found that directed downwardly one during being gone to vertically according to ruler by level
The first transverse tube at end will gradually fill up by liquid by the initial state full of air, and liquid can only be carved by the end
Short tube at degree enters, all larger by the fluid flow and flow velocity of short tube, it is sufficient to go out gas viscous at this during this
Bubble.When the original state of the second following transverse tube of the other end is filled with liquid, since the end tilts upwards, the pipe of the second transverse tube
Intracavitary liquid converges in the rectangular tube at middle part and then the first transverse tube towards lower end is supplemented, and gas enters towards upper end during this
In second transverse tube, can only pass through by the short tube of one end upward, during this at this gas flow of tubule and flow velocity all compared with
Greatly, also it is enough to go out bubble viscous at this.Horizontal ruler is slowly at the uniform velocity gone to close to level, the intraluminal gas of this process
Or the mobility status of liquid is just the opposite, and fragmentary bubble and bubble is not present in the short tube at both ends at this time, then can carry out water
Flat measurement.
Further, the both ends of first transverse tube and the both ends of the second transverse tube be equipped with respectively with the first short tube and second
The diameter contracting portion of short tube connection, the shape in diameter contracting portion are funnel-shaped.
As can be seen from the above description, funnel-form is conducive to improve rate of the liquid by short tube, being conducive to will be intraluminal viscous
Stagnant gas bubble washes out.
Further, the side wall of the rectangular tube is equipped with an aperture, and the tapping is sealed with rubber membrane.
As can be seen from the above description, this structure can be coordinated due to the intracorporal pressure change of chamber caused by expanding with heat and contract with cold.
Further, the colored liquid is made of coloring agent, antifreezing agent and water.
Further, the material of the connecting pipe is transparent plastic.
Further, the level body and connecting pipe are rigidly connected.
