Cross Correlation Mass Flowmeter Using Pulse Heating Method

Abstract

The aim of this study is the development of a novel nonintrusive mass flowmeter for the moved bed gravity flow of the new process, i.e.: the synthetic naphtha and hydrogen making reactor and DRI (Direct Reduction for Iron Orr) reducing petroleum and coke coal. One of the authors already developed cross correlation method, steady state heat transfer method and PZT acoustic emission method. This paper describes a prototype of a new cross correlation method using a pulse heating marking signal (JPA 1999-23339). The steady state heat transfer type is improved ale to +-0.8 % full scale in this 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 temperature against choking the feed powder on the surface of the temperature sensors.
