The precursors for the manufacture of colour pigments are dissolved in the dissolving tank. These precursors are mainly Naphtha based, and, depending on the formulation, water and sodium hydroxide solution are added as solvents for the production of the basic pigment solution. An agitator ensures uniform mixing of substances as they are added. The level measuring system is needed to ensure reliable values that are delivered to the control system.

Measurement is independent of the process conditions
Cost effective
Reliable, maintenance-free operation
User friendly
Simple installation from above through a small opening
