Abstract

An apparatus for measuring and indicating mass throughput of a fluid moved in a channel by a processing machine includes first to fourth measurement value pickups, first to third divider stages, first to fourth resistances, first to fifth multiplier stages, an adder for forming a difference ##EQU1## between an output signal of the first divider stage which is weighted with the first resistance, a memory of characteristics of the processing machine which has stored therein an appertaining volume number as a function of a magnitude of an output of the second divider stage and of the fourth measurement value pickup, and a measurement value indicator for indicating an output of the third divider stage weighted by the fourth resistance which is the mass throughput ##EQU2##
