Abstract

The invention belongs to the technical field of equipment measurement and especially relates to a container volume measurement device and a measurement method based on secondary micro-variation allowance pressure principles. The measurement device comprises a measured container, wherein the measured container is connected to a differential pressure sensor and an isothermal reference container (4) by a pipeline; a precise piston is disposed between the measured container and the differential pressure sensor (3), and a left valve is connected between the differential pressure sensor and the precise piston; and a right valve is connected between the isothermal reference container and the differential pressure sensor. The measurement device is used for container volume measurement and can be used in rapid, accurate and nondestructive volume measurement of various kinds of containers with complicated structures.

Description

technical field [0001] The invention belongs to the technical field of equipment measurement, and in particular relates to a container volume measurement device and method based on the principle of secondary micro-variable differential pressure, which can be used for fast, accurate and non-destructive measurement of the volume of various complex structures. Background technique [0002] Volume is one of the basic physical quantities of containers. Since various containers have different technical characteristics such as volume accuracy, application occasions, storage medium, sealing state, and structural form, the measurement methods of their volumes are also very different. At present, among the various measurement methods of the volume of complex structure containers, the measurement method is more commonly used. The so-called measurement method is to measure the mass and density of the medium (usually liquid) that the container can hold first, and then calculate the volu...
