The measurement and control of the percent consistency of pulp leaving a blow tank in a pulp operation is improved by using digester data and additional temperature measurements. The percent consistency of pulp is determined by using the following data: 1) the temperature and relative amounts of dry pulp, liquid and dissolved solids in a blown mixture entering the blow tank; 2) the temperature and amount of dissolved solids in a first stage filtrate liquor; and 3) the temperature of a diluted pulp mixture leaving the blow tank. Once the percent consistency of pulp is accurately measured, this value is then used to control the tonnage rate of pulp entering a first washer in a pulp washing operation.
