Designing and Realization of Differential Pressure Densimeter for Heavy Medium Coal Preparation Based on MCU

The density of heavy-medium coal slurry is a very important parameter and guideposts in coal preparation technique. According to heavy-medium coal preparation processing, the paper designs a differential pressure density meter. It introduces the design principle of the densimeter, the primary instrument and the hardware design of the secondary instrument. But else, it gives an experiences temperature compensation formula and calibration method.
