Abstract

A method and device for determining the consistency of a non-Newtonian fluid in accordance with USDA Bostwick consistency standards comprises diverting a partial stream from a main production stream of the fluid. The flowrate of this partial stream in weight per time is measured under predetermined pressure drop conditions. The USDA Bostwick value of consistency is then derived from the measured flowrate in accordance with a predetermined functional relationship.
