Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0031] High-precision portable density testing device of the present invention, such as figure 1 As shown, it includes a measuring container 1 connected through a hose group and an auxiliary container 2 with adjustable height. The measuring container 1 is placed on a load cell 3, and the load cell 3 is connected to a digital display operator 4. The display operator 4 includes a data processing module and an input module, a register module, and a display module connected to the data processing module. Wherein, the data processing module is used to perform operations on relevant data, the input module is used to input data, the register module is used to register data, and the display module is used to display data. The auxiliary container 2 communicates with the measuring container 1 through a hose group to facilitate adjustment of the height of the ...

Abstract

The invention discloses a high-precision density measuring method, and the existing density measuring instrument has poor measuring precision. The invention includes the following steps: putting an object to be measured in a measurement container, weighing the mass of the object to be measured by a weighting sensor; taking out the object to be measured, adding appropriate solution with known density to the measurement container so as to be able to submerge the object while not overflow after the object to be measured is put in, recording a liquid level of the solution; then putting the object to be measured in the measurement container, adjusting the height of an auxiliary container, keeping the liquid level in the measurement container agreement with the liquid level in a third step by means of communication of a hosepipe group; operating a digital readout controller and calculating the density of the object to be measured according to the following formula by using the digital readout controller and displaying: rho(object)=rho0m1 / (m0m2), wherein rho(object) is the density of the object to be measured, rho0 is the density of liquid, m0 is the mass of the liquid in the measurement container in the third step, m1 is the mass of the object to be measured, and m2 is a total mass of the object to be measured and the liquid in the measurement container in a fifth step.

Description

technical field [0001] The invention belongs to instruments and meters, and is mainly used in chemical industry and mineral processing, especially in the identification of precious stones, the detection of low-grade precious metal ores, the measurement of pores in die-casting parts, etc., which require extremely high precision. Background technique [0002] In the fields of chemical industry, mineral processing, and material identification, density is the most basic constant of matter, and it is the data often used in production and scientific research. The measurement of material density is one of the main means of material quality control. Through density measurement, the fluctuation of material composition and process conditions such as temperature can be controlled. For example, in the process of oil drilling, abnormal formation pore pressure is extremely dangerous for oil wells, which may cause accidents such as well kick, blowout, lost circulation, well diameter shrink...
