Silica concentration in a liquid can be measured using the colorimetric measuring principle. This video shows what it is about and how this measuring principle works.

Colorimetric system for the monitoring of boiler feedwater, steam, condensate and ion exchangers

Liquiline System CA80SI provides precise online analysis of silica and helps protect plant equipment from glass-like deposits ensuring optimum performance of turbines and ion exchangers. Its unique combination of peristaltic and high-precision dispenser pumps enables extremely reliable operation and low maintenance. The silica analyzer offers advanced diagnostics and can be easily adapted to your process needs by retrofitting up to 6 channels and connecting up to 4 Memosens sensors.
