It when design, should ensure that float and the transmission rod weight of attachment should be lighter than buoyancy, float made to have upward buoyancy to be conducive to normal measure.
The measuring principle of the utility model：
1) definition of buoyancy is that F floats=G rows (i.e. buoyancy of object is equal to the gravity that liquid is arranged when object sinks).
2) derivation formula：F is floating=and ρ liquid gV rows are (in formula：ρ liquid-fluid density, units/kg/m3；G-acceleration of gravity, g
=9.8N/kg；V arrange-arranges the volume of liquid, the i.e. volume of float, unit m3；1N=0.1kg)
F floats=9.8 х V row х 0.1 (units/kg) of ρ liquid х
3) when buoyancy is more than float weight, object floats；When object is static, equilibrium state is kept, i.e. gravity and floating
Power is equal in magnitude.
The application is surveyed using the additional one power F consistent with gravity direction, and float is all submerged in measured medium, is made
Float keeps equilibrium state in the medium, and the size of buoyancy can be calculated by being measured to additional power (F surveys), to learn
The density of medium.
F floats=F surveys+G (float and power transmission attachment total weight)
ρ liquid=(F surveys+G)/0.98 х V rows
G floats and transmission rod lightweight packages, units/kg；V rows are float volume, and unit m3 is known after float sizing.
