Problems solved by technology

[0006] 1. When testing different marks on the glass float meter, it is necessary to replace the testing liquid with different densities; and the testing liquids currently used are mostly toxic and flammable organic solutions
[0007] 2. Unable to verify the low-range measurement density is less than 650kg / m 3 ) of the glass float meter, because no test solution with stable density has been found so far
[0008] For density less than 650kg / m 3 For the verification of the glass buoymeter, some domestic units have made some useful attempts by using the static weighing method, but it is common to need to manually pull the sling when calibrating the different calibration marks of the glass buoymeter, which is troublesome and labor-intensive. Larger, less efficient work

Abstract

The invention relates to the technical field of the detection and the calibration of a hydrometer, in particular to a calibration device and method for calibrating a petroleum hydrometer. The calibration device comprises a fixed mount, a thermostatic bath and a scale, wherein the thermostatic bath is arranged in the fixed mount, the scale is arranged on the top surface of the fixed mount, a lifting rope is arranged below the scale, a glass measuring cylinder is arranged in the thermostatic bath, the glass measuring cylinder comprises a main measuring cylinder and an auxiliary measuring cylinder, the main measuring cylinder is communicated with the auxiliary measuring cylinder by a liquid level regulating device, and a thermometer is arranged in the main measuring cylinder. The invention realizes the switching among different calibration marking points of the hydrometer based on the vertical movement of the liquid level of the reference liquid, so that the liquid level of the referenceliquid can be tangential to the required calibration marking point, thereby meeting the calibration requirements of the hydrometer, filling in the gap that a low-range petroleum hydrometer can not becalibrated, expanding the calibration range of the petroleum hydrometer, improving the calibration automation degree, enhancing the calibration efficiency, reducing the measuring error and improving the calibration uncertainty level.

Description

Technical field: [0001] The invention relates to the technical field of detection and calibration of density meters, in particular to a calibration device and method for calibrating petroleum density meters. Background technique: [0002] Density is an important physical quantity that characterizes the properties of matter. Density measurement plays an important role in the research of various material properties in physics, chemistry, metrology, oceanography and other disciplines. It involves petroleum, chemical industry, metallurgy, building materials, light industry, trade, coal, medical care and other national In many fields of the economy, it has been widely used in many industrial sectors. Therefore, no matter from an economic or technical point of view, accurate density measurement is of great significance. In order to ensure the consistency of the liquid density value, my country established a liquid density reference device based on the liquid static weighing meth...
