Abstract
The invention relates to a device and method of measuring the liquid density, two cups and a spring constructs the simple device which is used to measure the liquid density, thereinto, a lesser transparent cup is the inner cup to measure the liquid density, a segment of density scale which expresses the density value and fixed scale value of decanted liquid to be measured are engraved on the surface of the cup, the lower part of the cup is connected with the spring, the out part of the cup is a outer cup. When liquid is measured with this device, quantitative liquid is decanted into the inner cup, when the decanted liquid reaches the fixed scale value; the scale value in inner cup which is corresponding to the outer cup is the density of liquid to be measured. Measuring the liquid density with this method and device, the quantity of measured liquid is little, the structure of the device is simple, and it has advantages of briefness and intuition.
Description
One, technical field
The present invention relates to a kind of device of measuring fluid density, the invention still further relates to the method for using this device.
Two, background technology
At present, the method for known measurement fluid density has multiple, but basic principle all is after measuring the quality and volume of liquid, through calculating, just can draw density of liquid again, and this method must be through repeatedly measurements and calculations process, and formality is complicated and error is big.Also have a kind of method to be to use densitometer, though this method can once be measured the size of fluid density, required amount of liquid is more.Therefore, people are sought after a kind of device and method of measuring fluid density more intuitively, fast.
Three, summary of the invention
The objective of the invention is to provide a kind of method of measuring the device of fluid density easily and using this device.
The device of measurement fluid density of the present invention is to realize by following technical solution: the device of measurement fluid density of the present invention, it comprises two cups, a spring, wherein, with the interior cup of a less transparent cup as the measurement fluid density, its surface engraves the density scale that a segment table shows density values continuously, connect spring then down, outer cup of overcoat.
Adopt the method for this measurement device fluid density to be: the principle that is directly proportional with gravity according to density of liquid, in interior cup, pour the different liquids of the known density of some into, then, according to the degree of interior cup decline, at the continuous density value scale of interior cup surface rendering.Then, when measuring the liquid of unknown density, as long as pour the fluid to be measured of some in interior cup, interior cup can descend under action of gravity, and at this moment, the scale value in outer cup mouth is pairing on the cup is exactly the density of this fluid to be measured.
Adopt this method and apparatus to measure liquid, the negligible amounts of fluid to be measured, and also apparatus structure is simple, has advantages such as easy, directly perceived.
Four, description of drawings
Fig. 1, the present invention measure the apparatus structure synoptic diagram of fluid density.
Among the figure: cup in the 1-, the outer cup of 2-, 3-fixedly scale value represents the position, the density value scale that 4-is continuous, 5-spring.
Five, embodiment
Reaching embodiment with reference to the accompanying drawings is described further.
The device of measurement fluid density of the present invention, it comprises two cups and a spring, wherein: as interior cup 1, its surface engraves the fixedly scale 3 that a segment table shows the continuous density value scale 4 of different densities value and pours fluid to be measured into continuously with a less transparent cup.In the present embodiment, the fixedly consumption of the fluid to be measured of pouring into is 10 milliliters, therefore, on interior cup 1, the fixedly scale value that engraves 10 milliliters is represented the position, lays a spring 5 below interior cup, and interior cup 1 can move up and down under the effect of gravity and spring, outer cup 2 of its outside cover, the degree that cup descends in being used to indicate.
Adopt the method for this measurement device fluid density very simple, it is the principle that is directly proportional with gravity according to density of liquid, pours the different liquids of 10 milliliters known density earlier in interior cup, then, according to the degree of interior cup decline, at the continuous density value scale 4 of interior cup surface rendering.Like this, when measuring the liquid of unknown density, as long as in interior cup, pour 10 milliliters fluid to be measured into, interior cup can slowly descend along with the increase of pouring fluid to be measured quantity into, and the scale value on outer glass 2 the pairing density scale of mouth also can change to some extent, when the fluid to be measured of pouring into arrives 10 milliliters scale mark, stop to add fluid to be measured, at this moment, the scale value on the suitable for reading pairing continuous density value scale of outer cup 2 is the density of this fluid to be measured.
Claims (2)
1, a kind of device of measuring fluid density, it comprises two cups and a spring, it is characterized in that, with a less transparent cup as interior cup (1), its surface is carved the continuous density value scale (4) of the preceding paragraph continuously and is poured the fixedly scale value (3) of fluid to be measured into, a spring of following placement (5) of interior cup, an outer cup of overcoat (2).
2, this measures the method for fluid density device to use the described use of claim 1, it is characterized in that, it is the principle that is directly proportional with gravity according to density of liquid, in interior cup, pour the different liquids of 10 milliliters known density earlier into, then, degree according to interior cup decline, at the continuous density value scale (4) of interior cup surface rendering, then, when measuring the liquid of unknown density, as long as pour 10 milliliters fluid to be measured in interior cup (1), interior cup (1) can slowly descend along with the increase of pouring fluid to be measured quantity into, scale value on the suitable for reading pairing continuous density value scale (4) of outer cup (2) also can change to some extent, when the fluid to be measured of pouring into arrives 10 milliliters scale mark, stop to add fluid to be measured, at this moment, scale value on the pairing density scale of mouth of outer cup (2) is the density of this fluid to be measured.
