A mixing apparatus for a plurality of turbulently flowing fluid flows varying in temperature and/or composition includes a mixing chamber having a non-circular or predetermined cross section and a straight or curved center line. A plurality of single-conduit and parallel or radial deflector elements are disposed beside the mixing chamber and staggered in the direction of the center line. The deflector elements receive a fluid flow being oriented at an angle relative to the center line and staggered laterally. The deflector elements deflect the fluid flow tangentially into the mixing chamber. The mixing chamber has an outlet opening for the exit of a mixed fluid flow. In a gas-cooled, high-temperature nuclear reactor with a circular outline, the mixing apparatus has a horizontal, annular mixing chamber with a plurality of sectors. Horizontal annular conduits receive at least one fluid flow. A plurality of vertical conduits are disposed above the sectors and have upper ends connected to the horizontal annular conduits and lower ends connected to the mixing chamber. An outlet opening communicates with the mixing chamber. The sectors havie a plurality of bores formed therein in the vicinity of the outlet opening for receiving absorber material.

Mixing apparatus for fluids

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##
