ABSTRACT:
An improved impeller for a rotating consistency transmitter and a method of measuring the consistency of pulp slurry flowing in a main pipeline. The impeller includes an intercepting surface designed to minimize the creation of turbulence in pulp slurry and the frictional forces on the front edge thereof when rotated in the pulp slurry. Using the impeller, a method of measuring the consistency of the pulp slurry is provided which measures the work done by forces acting on the impeller.
