Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] In the solution for measuring the liquid level of the gas tank in the present invention, a measuring tube with an inner tube (closed at the lower end) is connected by a steel rope and a pulley, and the steel rope connects the inner tube and the bell jar, and the rise and fall of the bell jar drive the descent of the inner tube and rise. Water is injected into the measuring tube, and the water level in the measuring tube changes accordingly thro...

Abstract

The invention relates to the technical field of industrial measurement control, and provides a liquid level measuring device and method for a gas tank. By a simple device, measurement of the liquid level of the gas tank is transformed into the measurement of the change of height of the liquid level of the liquid in a tube, and then, pressure change difference caused by the change of the liquid level is measured so as to calculate the liquid level of the gas tank. In the scheme of the invention, the principle of measurement is simple, amount of necessary measured values is less, calculation issimple and convenient, accuracy and effect of measurement are both ensured, and materials and installment construction thereof are simple and economic, so that the device and the method can be widelyused in the fields of petroleum, chemical industry and the like.

Description

technical field [0001] The invention relates to the technical field of industrial measurement and control, in particular to a gas cabinet liquid level measuring device and method. Background technique [0002] Gas cabinet is a kind of container equipment used to store various industrial gases, or to balance the unevenness of gas demand. In petroleum, chemical, pharmaceutical and other industries, gas cabinets are often used to store industrial production processes. Gaseous substances used or obtained. Among them, gas cabinets based on storage pressure requirements are usually divided into two categories: low-pressure gas cabinets and high-pressure gas cabinets. Most industrial gases do not have strict requirements on storage pressure, so low-pressure gas cabinets are much more widely used than high-pressure gas cabinets. The low-pressure gas cabinet is divided into two types: wet type and dry type. The wet type low-pressure gas cabinet is currently the simplest and most com...
