AI Technical Summary

Technical Problem

Existing methods for detecting the remaining liquid in drum-shaped containers are inefficient and highly subjective, and cannot accurately determine the linear relationship between liquid level changes and the remaining liquid.

Method used

Using a liquid level detection device and a calculation device, the geometric parameters and liquid level height of the drum-shaped container are obtained. The remaining liquid volume is calculated using four common drum-shaped container expressions. The liquid mass is obtained by weighing and the density is calculated to determine the liquid volume when the container is full. The liquid level is obtained by a liquid level sensor and the remaining liquid volume calculation formula is applied for accurate detection.

Benefits of technology

It improves the accuracy and efficiency of detecting the remaining liquid in drum-shaped containers, reduces production costs, and is applicable to four common types of drum-shaped containers.

Abstract

This invention provides a method for detecting the remaining liquid volume in a drum-shaped container. The specific steps include: obtaining the inner diameter D at the center of the drum-shaped container, the inner diameters d at both ends of the drum-shaped container, the inner height L of the drum-shaped container, the actual liquid volume V0 when the drum-shaped container is full, and the liquid level h when the drum-shaped container is full. 满 And the liquid level h in the drum-shaped container to be tested; the four drum-shaped container expressions y and the farthest distance x from the center of the liquid surface in the corresponding drum-shaped container to the point of contact between the liquid and the drum-shaped container. L Select y and x in the expression L ; Select the y and x L The measured values ​​of D, d, L, and h are used to calculate the remaining liquid level in the drum-shaped container. The method of this invention proposes different expressions applicable to four common types of drum-shaped containers and different situations of liquid level height, which improves the accuracy of detecting the remaining liquid level. Furthermore, the method of this invention has good applicability and can provide effective method support for the management of common drum-shaped containers during use.
