摘要

提出一种新的管内流体温度测量方法,该方法以微波谐振腔测量液体复介电常数为基础,结合Debye和Cole-Cole方程,反演得出被测液体温度值。首先简要介绍常用管内流体温度测量方法存在的不足,其次,详细介绍测量系统工作原理,以两种工作模式TM010和TM011为例,测量纯水展开实验。通过对比两种工作模式下的测量结果,证实了所提出方法在准确测量被测材料复介电常数的同时,可以实现快速准确的温度测量。测量结果表明,TM010模式时Cole-Cole方程的虚部计算方式误差最小。所提方法可解决目前管内流体温度测量中开口测量安全隐患大及方案复杂等问题。

Abstract

A new method for measuring the temperature of the fluid in a tube is proposed, which is based on the measurement of the complex permittivity of the liquid using a microwave resonant cavity, and combines the Debye and Cole-Cole equations to obtain the temperature value of the measured liquid. Firstly, the shortcomings of the commonly used methods for measuring the temperature of the fluid in the tube are briefly introduced. Secondly, the working principle of the measurement system is introduced in detail. Taking the two working modes of TM010 and TM011 as examples, the measurement of pure water is carried out. By comparing the measurement results in the two working modes, it is confirmed that the proposed method can achieve fast and accurate temperature measurement while accurately measuring the complex permittivity of the tested material. The measurement results show that the calculation method of the imaginary part of the Cole-Cole equation has the smallest error in the TM010 mode. The proposed method can solve the problems of large safety hazards and complex solutions in the current measurement of fluid temperature in the pipe.
