Black liquor and green liquor densities are measured reliably by radiometric systems, which are clamped on to the pipe and provide highly repeatable readings. The measurement is carried out without contact and is therefore unaffected by the high temperature and the chemical properties of the liquor. Installation on existing lines is easily completed without process downtime.
