Isotope density meter and Cy-type differential pressure density meter are two kinds of density meters commonly used in coal preparation plants. They are mainly used to test the density of the suspension in the dense medium coal preparation process. There are also differences in performance characteristics. This article is excerpted from "A Brief Discussion on Density Meters for Coal Preparation" by Du Zhenbao and other scholars. The difference between isotope densitometers and Cy-type differential pressure densitometers is introduced below:
isotope density meter
The isotope density meter is a density measuring instrument that is widely used in coal preparation plants at present. It has a long history of application in coal preparation plants. The awareness of isotope density meters is also relatively high. Its performance characteristics are as follows:


Cy-type differential pressure density (concentration) meter
