Abstract
The invention relates to an instrument able to measure liquid density. The instrument is composed of a metal material shell, a spring, a hook, a pointer, and a metal body. The shell is marked with scales. When the metal body is immersed in a liquid, the liquid density value can be read at a pointer indication position.
Description
Technical field
The present invention relates to the mensuration of fluid density, can conveniently measure exactly fluid density, extensive in life, production and science and technology (particularly in the teaching) application prospect.
Background technology
At present, the counterweight that known densitometer is contained lead shot by glass tube and lower end forms, purpose be while making it static, can in liquid, erect floating.During measurement, need more liquid, and scale is inhomogeneous, interpolation large, carry inconvenience.
This densitometer can be measured fluid density in a big way, and scale is even, easy to operate, portable.
The technical solution adopted for the present invention to solve the technical problems is: the metallic object of gravity, given volume is immersed in different liquids, and the buoyancy be subject to is different, and then the size of buoyancy is converted into to the size of fluid density.As long as metallic object is immersed in liquid, can read fluid density.
Summary of the invention
1. material: one, spring (measurement range 1N left and right), pointer, hook, scale panel, volume are 10cm
3Any plumbous counterweight of notes in heavy 0.8N() one of cylinder iron block.
2. assembling: spring, pointer, hook, scale panel are assembled, with the weight beam shape, the lower iron block of placing of hook.
3. scale: while not hanging iron block, pointer indication position is designated as A, and iron block is hung over to pointer position under spring (real be 0.8N place) work one mark B; Will be between the mark of B~A divide 8 equal portions, namely gravity (unit: N) be respectively 0.8,0.7,0.6 ... 0.1,0 place, mark respectively 0,1,2,3 ... 7,8, then above panel, put on " density * 10
3Kg/m
3" printed words, but refinement scale also, by each lattice little lattice of decile ten again.
4. wiring layout: referring to Figure of description
5. measuring method:
(1) derby is hung over to hook upper (derby does not hang over hook above at ordinary times, in order to avoid spring stress affects precision);
(2) carrying draw ring on densitometer, allowing in derby submergence testing liquid, pointer refers to a place;
(3) reading fluid density is a * 10
3Kg/m
3.
6. instrument advantage:
This densitometer is simple in structure, easy to operate, because scale is even, is convenient to scale, so measure accurately, measures density range large, can measure density 8.0 * 10
3Kg/m
3With interior fluid density.Can also be according to actual needs, thin indexing, improve measuring accuracy.If employing platinum, the material that the iridium isodensity is large, the densitometer that adopting uses the same method makes can be measured the liquid (as mercury) of any density.
[0009] accompanying drawing explanation
Accompanying drawing 1 is the new Type of Liquid Density Meter front view.
Claims (3)
1. a liquidensitometer, have spring, hook in metal shell, and the scale panel is arranged on shell, and pointer is arranged on hook, to determine scale, and metallic object of the lower extension of hook.
2. according to the described densitometer of right 1, it is characterized in that: metallic object has certain volume, certain gravity.
3. when being immersed in metallic object in different liquids, the pointer indicating position difference, corresponding different scales, can draw density value.
