Embodiment

[0030] Such as figure 1 As shown, it is a schematic diagram of the built-in method of the present invention to measure volume, consisting of a gas supply system 1, a standard volume 4, a small container 3 of unknown volume, a large container 8 of unknown volume, vacuum gauges 6 and 10, isolation valves 2, 5, Composed of 7 and 9.

[0031] The gas supply system 1 is connected with the small container 3 of unknown volume and supplies gas for the small container 3, the standard volume 4 is put in or taken out through the flange on the small container 3, the pressure in the small container 3 is measured by a vacuum gauge 6, and the large container The pressure of 8 is measured by vacuum gauge 10), and the gas extraction system is connected with the large container 8 and evacuates gas therefrom.

[0032] The implementation steps are as follows:

[0033] (1) Do not put the standard volume 4 in the small container 3;

[0034] (2) Start the air extraction system, open the isolation ...

Abstract

The invention relates to a device for measuring volume via inlay method, for measuring the volumes of static expansion method vacuum containers and the container demanding accurate measurement, and especially the volumes of irregular container. The device is composed of a gas supply system, a standard volume, a small container of unknown volume, a large container of unknown volume, a vacuum gauge, a block valve and a gas exhaust system, wherein the gas supply system is connected with the small container of unknown volume for supplying gas to the small container; the standard volume is put in or taken out via a flange on the small container; the pressure in the small container is measured by the vacuum gauge; the pressure in the large container is measured by the vacuum gauge; and the gas exhaust system is connected with the large container for exhausting gas from the large container. The invention utilizes a standard volume rod which is measured accurately as a reference volume, to be arranged into a container of unknown volume, utilizes gas expansion method and refers to pohl law to calculate the volume of the unknown container accurately. The method is suitable for measuring the volumes of irregular containers and can improve volume measurement accuracy significantly.

Description

technical field [0001] The invention relates to a volume measuring device with a built-in method. It can be used for volume measurement of static expansion vacuum containers and containers requiring accurate volume measurement, especially for volume measurement of irregular containers. This method can improve the accuracy of volume measurement. Background technique [0002] In a static expansion system, a basic method of determining the volume of a container is the gravimetric method, that is, the weight of the container before and after it is filled with liquid (usually water) is used to calculate the volume. Although this method can ensure accurate measurement of weight, it is difficult to measure the volume accurately due to the influence of air bubbles in the liquid and the dead space of the valve. For small containers, this phenomenon is more serious. [0003] Another method of measuring the volume of the container is the external method, and the measurement principl...
