I would like to ask the experts here: how do you control the materials used in the production of anhydrous hydrogen fluoride in a precise manner? What are the automatic control solutions for fluorite powder, 98% sulfuric acid, and 105% sulfuric acid?

The measurement error for fluorite using a Schenck scale is less than 2%, while flow meters are used for 98% acid and 105 acid

Fluorite powder is measured using a dynamic scale, connected to a flow meter for concentrated sulfuric acid, and controlled through a centrifugal pump and control valve
