Liquid level measuring method

Abstract

The invention relates to a liquid level measuring method, which uses a liquid level measuring device to measure the liquid level in a container. The liquid level measuring device comprises a shell, aliquid level module and a pose module which are positioned in the shell, and a control module. The liquid level measuring method comprises the following steps: using the liquid level module to measurethe vertical height h from the shell to the liquid level; measuring an included angle alpha between the container and the horizontal plane by utilizing the pose module; and calculating the actual liquid level height H by utilizing the control module according to L, h and alpha. Algorithm processing is carried out on the liquid level height and inclination angle of the container through the liquidlevel module, the pose module and the control module, and therefore, the liquid level of the container is obtained. The liquid level measuring device can be installed at any position of the bottom ofthe container, the actual liquid level height can be accurately calculated when the container is located at any inclination angle, the accuracy is high, the installation is convenient, and computer programming automatic measurement is facilitated.

Description

technical field [0001] The invention belongs to the field of test and measurement, and in particular relates to a liquid level measurement method. Background technique [0002] In the fields of construction machinery, petroleum processing, papermaking, metallurgy, ships and boilers, it is usually necessary to detect the liquid level of the liquid inside the container. For example, with the rapid development of the country, the construction of high-speed rail, real estate, and large-scale projects is inseparable from a large number of construction machinery and equipment. The working environment of construction machinery is harsh, the task is heavy, and the energy demand is large, so the fuel consumption measurement of construction machinery has practical significance . [0003] Taking the liquid level measurement of construction machinery as an example, the existing liquid level measurement mainly includes three types, namely: [0004] 1) By installing a buoy sensor in the...

Problems solved by technology

This method is more accurate in measuring fuel consumption, but the cost is high. At the same time, the oil circuit needs to be modified. It will cause some troubles to install the construction machinery that has already left the factory. In some extreme cases, it may cause Poor oil supply

[0007] To sum up, the existing liquid level measurement methods have problems such as poor accuracy and inconvenient installation.
