Principle of work of the present utility model is:
First the volume v of the water identical with testing sample volume is obtained with volume displaced instrument
1{ its principle is: Boyle-boyle's law (2p
0) (v
0-v
1)=p
0[2 (v
0-v
1)]=υ RT, during isothermal, gas atmosphere reduces by half double volume, wherein v
0for the volume of container, v
1for sample volume }.Then obtain the water equal with sample to be tested quality with the quality replacement instrument of sample, remember that the volume of these quality water is v
2(its principle is Archimedes principle).Finally with Density Measuring Instrument make with sample to be tested equal-volume with etc. the liquid level of water of quality consistent, { its principle is then to obtain the density of testing sample by reading data
(when sectional area is identical), density measure is converted into length ratio }.
