Cross correlation mass flowmeter using pulse heating method

The aim of this study is the development of a novel nonintrusive mass flowmeter for the moving bed gravity flow of the new process, i.e., the synthetic naphtha and hydrogen making reactor and DRI (direct reduction for iron ore) 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 improvable 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 device is not prone to the accumulation on its surface of powder used in the process.
