In this embodiment, the liquid density measurement principle is as follows:

by means of Archimedes' principle, the buoyancy received by an object in a liquid is equal to the gravitational force received by the liquid being displaced.

F_{Floating body}＝ρ_{Liquid for treating urinary tract infection}gV_{Row board}

The weight of a substance with a fixed volume immersed in liquid is measured by using an explosion-proof electronic balance and adopting suspension type weighing, and the inherent mass of the fixed substance is stored in the system, so that the buoyancy of the measured substance in the liquid can be directly calculated by the balance. Therefore, the density value of the measured liquid can be directly obtained through conversion.

Wherein: m is the mass of the fixed volume of material and M is the mass of the object weighed in the liquid. The M value in the formula can be measured by a balance to obtain the inherent mass, or the M value and the V value can be calculated by the density calculation of two known liquids_{Row board}The value is obtained.

In the embodiment, the density meter measures the mass of the density sampling ball immersed in the liquid in a hanging mode, namely the mass value m in the formula I is measured, and the density of the measured petroleum product is directly obtained through calculation.

The oil drum is the container that holds the petroleum product, but the volume requirement of holding is fixed, and when holding to a certain extent, the petroleum product flows out to connect in the middle of the oil drum through the spill valve, has guaranteed the inside page height of oil drum, and then ensures that the volume of the density sample ball that immerses in the liquid keeps invariable.

The density sample ball is a standard object of various measurement systems, has constant volume and constant mass, and finally obtains the density of the measured liquid by utilizing the inherent parameters of the density sample ball.

And the oil drain valve is used for discharging the measured object to other devices through the oil drain valve after one sample is measured.

In this embodiment, the measurement process is as follows:

when the same kind of substances are measured for the first time, the density sample ball is wiped clean and hung on the hook on the bottom surface of the density sample ball, and then the density instrument system is restored to a zero state according to the zero setting key on the density instrument.

Opening the oil drum cover, then slowly injecting petroleum products such as gasoline into the oil drum, stopping injecting the gasoline when the gasoline overflows from the oil spill valve, covering the oil drum cover, after the oil spill valve stops overflowing, reading the numerical value displayed by the density meter at the moment, wherein the numerical value is the measured gasoline density value.

And finally, discharging the gasoline in the container through an oil discharge valve.

When the density is measured again, the density sample ball may be attached with gasoline, the display of the density meter may not be 0, but cleaning is not needed at the moment, and a zero key can not be pressed any more. When no product is in the same category in the measurement, the gasoline attached to the density sample ball is blended into the gasoline sample, and the error can be ignored due to the extremely few attached products. Therefore, the subsequent process is simple and convenient when the same kind of samples are measured.

It is desirable to wipe the density sample ball and take a zeroing action on the densitometer system when changing article types or for long term use for first time applications.

In this embodiment, an electronic balance is used as a core measurement portion, and is converted into a density measurement result through conversion of system software, and the liquid density value is calculated by measuring the buoyancy of a standard solid suspended in liquid by the electronic balance. The higher the balance accuracy, the greater the volume of the standard solid (density sample sphere) the higher the accuracy of the measured density. The product adopts a balance with the measuring range of 200g and the precision of 0.001g, and if the standard solid volume is 100cm3, the buoyancy force borne by the balance is within the measuring range of the balance, and the density equivalent value of 0.001g/100cm3 can be measured within the volume of 100cm 3. A more accurate density measurement can thus be obtained with a balance for measurements suspended in a liquid.
