Abstract

The invention provides a measurement method of liquid level and position of a tank body. Distribution situation of liquid in the tank body is calculated according to distribution situation of dielectric constant distributed in every section of the measurement structure, and thereby relevant information such as average density and phase content of the liquid in the tank body can be calculated. The measurement method of the liquid level and the position of the tank body has the advantages of being simple in structure and design, different from the traditional capacitance measurement method, and capable of greatly reducing influences of distribution parameters and other effects on measurement, and improving measurement accuracy of the system due to the fact that sectional type time-sharing measurement is adopted.

Description

technical field [0001] The invention relates to a method for measuring the liquid level and interface of a tank, which is suitable for the liquid distribution of two kinds of density mixed liquids with different component contents or the measurement of the liquid level and interface of stratified liquid in the tank, and can be used according to the distribution The relevant information such as the average density and phase content of the liquid in the tank is released. Background technique [0002] At present, there are many products for measuring liquid level, but there are relatively few measuring interface, mainly including magnetostrictive liquid level gauge, float type liquid level gauge, differential pressure method, guided wave radar level gauge, etc. [0003] Magnetostrictive and displacer type liquid level gauges are subject to liquid layer distribution, too small density difference and other reasons, which lead to excessive measurement errors of boundary level, and...
