Cross correlation mass flowmeter using pulse heating method (No. 3)

Abstract

The aim of the study is the development of a nonintrusive mass flowmeter for the moved bed gravity flow of the new process, i.e.: DRI (direct reduction process for iron ore) and the synthetic naphtha making reactor reducing the coke coal and petroleum. One of the authors has already developed a cross correlation method, steady state heat transfer method and PZT acoustic emission method. The paper describes a prototype of a new cross correlation method using a pulse heating marking signal based on the past proceedings. The steady state heat transfer type is improved to +-0.8% full scale in the paper and it is the most available for the new process till the third oil crisis or reconstruction of coke. This new prototype should be more useful for the derivative of temperature against choking the feed powder on the surface of the temperature sensors. The paper describes the comparison between the accuracy of the signal and the wall materials (heat conductive or adiabatic).
