Abstract

In order to reduce the influence of fluid velocity on a measurement of a concentration characteristic of a fluid, the magnitude of an r.m.s. signal V derived from a voltage induced in a sensor provided in relation to the fluid passage is adjusted using a factor dependent upon the measured velocity v of the fluid. Consequently, the accuracy with which the mass flow rate M of the solids in the fluid can be determined is improved.
