Abstract
A measuring system (10) for measuring the flow of solids (w.sub.s) in a fluid stream is disclosed which utilizes only two differential pressure measurements (.DELTA.p.sub.1 ; .DELTA.p.sub.2) indicating the pressure drop across different points of a venturi (12). The fluid having the solids entrained therein is passed through the venturi (12) and pressure drop measurements are taken at points of the venturi (12). These pressure drop measuurements (.DELTA.p.sub.1 ; .DELTA.p.sub.2) are transmitted to a microprocessor (15) which calculates these measurements (.DELTA.p.sub.1 ; .DELTA.p.sub.2) according to a predetermined empirical formula to yield an output signal indicative of the flow of solids (w.sub.s) through the venturi (12).
