Classification of tension tables
G0/177642008/380 387,1977
This standard classifies the tension tables according to Table A.1 as the basis for accuracy and verification. The selected density allows the measurement of the appropriate accuracy. The tension classification given in the specification does not exclude the use of surface tension tables as the basis for density calculation. As long as the surface tension is marked in meters on the density scale, the text can be marked with a density meter. The following table contains the tension values ​​of the liquid under test.

English proposal to use density as the basic system of density meter. It is proposed to use density as the basic scale of density meter. Point #The following is the intention of the country: a floating Xie Kang in the static liquid service simple tube cross health density meter push open the part of the micro-body sales stock most density meter can be connected:, because the ratio of the position, you can directly determine the scale value by the volume of each item.

) To limit the operation of a certain subject, use it as a waist. Estimate the mass of a liquid or prepare a liquid of known composition; use it to calculate the mass of a liquid of known volume. For materials, the density meter with the same density may be similar to any other density meter (because it can always be observed under the same fullness, use the density meter to calculate the density of the glass. The advantages of the density meter are very clear: with the help of the calibration device, it can be used! Anybody, this device is not only reliable with the density meter, but also can be used with other devices to determine the density. The density meter can be used with a simple table containing the fat way, thank you for the whip body. The national fertilizer density meter is applicable to all of these uses. You expect that these convenient services will appear because of the density of the meter that needs to be replicated and produced, but this advantage has unexpectedly shined in the world. Density has an advantage over relative density in that it has been taken through the air. Relative density also has this advantage. However, the concept of relative density is related to different degrees of exposure. It is more basic than density. It is often used as a ratio of the corrected air mass (i.e., the ratio of the corrected air mass). Sometimes, it is used as a test. The air is used to reduce this rate. Simply use a single-mass density meter, which will not cause uncertainty and error. The diagram in this world can be used to give full play to the air quality of the product. GB/T 17764-2008
