Embodiment Construction

[0029] 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.

[0030] see figure 1 , usually the fluid mixture in the container 1 is composed of two layers of liquid medium 4, 5, and above the liquid surface 2 is a vacuum or a layer of gas (or mixed gas). Since the gas density is extremely small, its influence is negligible, so The measurement of the medium interface in the container focuses on the measurement of the interface 3 between two different liquid media.

[0031] In the present invention, the device fo...

Abstract

The invention provides a device and method for measuring the interface of a medium in a container, relating to the technical field of industrial measurement control. According to the device and method disclosed by the invention, the height, the size and/or the weight, and the like of the mixing medium in the container can be monitored conveniently by means of the cooperative use of a radar level gauge and a differential pressure transmitter, the measuring principle is simple, the calculation speed is fast and the method is easy to realize. The device has the advantages of high measurement precision, not high demands on work environment and the measured medium, safety and convenience for operation, and easiness in installation and maintenance, and can effectively solve the problem of difficulty in the measurement of the medium interface in the prior art.

Description

technical field [0001] The invention relates to the technical field of industrial measurement and control, in particular to a device and method for measuring a medium interface in a container. Background technique [0002] Various towers, tanks, tanks, reactors and other containers are often used in petroleum, chemical, pharmaceutical and other industries to store reactants, collected materials and / or products used in the production process. Such media usually have no fixed form (generally Mostly fluids such as gas or fluid), and often a mixture of various media. Among them, the immiscible fluid mixture usually exists in a layered form in the container. To understand the composition of the mixture and accurately control the production process, It is necessary to measure the position of the interface of the stratified fluid. However, since these containers are usually closed containers, the chemical materials in them are usually toxic, corrosive or highly dangerous (such as ...
