Abstract
The CaCO.sub.3 content of a scrubbing suspension, especially for a desulfurizing apparatus for flue gas is measured by injecting an acid into a constant mass flow of the suspension circulating along a bypass and measuring the pH before and after such injection. The change in pH is compared with reference measurements and used as a basis for calculating the CaCO.sub.3 concentration.
