The apparatus comprises a first fluid line for conducting an intermittently flowing first fluid and a second fluid line for conducting an intermittently flowing second fluid, the two fluid lines being connected at a junction to a third fluid line, which forwards the two, particularly mixed, fluids.
The apparatus comprises a first fluid line for conducting an intermittently flowing first fluid and a second fluid line for conducting an intermittently flowing second fluid, the two fluid lines being connected at a junction to a third fluid line, which forwards the two, particularly mixed, fluids. Further, the apparatus comprises a first flow adjuster, inserted in the first fluid line for setting a volumetric or mass flow rate of the first fluid, and a second flow adjuster, inserted in the second fluid line for setting a volumetric or mass flow rate of the second fluid, as well as apparatus for generating a first control signal, representing an instantaneous setting value for the first flow adjuster, and a second control signal, representing an instantaneous setting value for the second flow adjuster. To produce the fluid mixture, the first fluid and the second fluid are made to flow into the third fluid line alternately. The invention is particularly suited for mixing fluids having different viscosities.

The apparatus as set forth in claim 1 wherein: the second meter at least intermittently measures a totalized volumetric or mass flow rate of the second fluid and generates a, particularly digital, second measured flow rate value, representing the totalized flow rate of the second fluid. 3. The apparatus as set forth in claim 2 wherein: the first flow controller generates the first control signal for the first flow adjuster by also using the second measured flow rate value, which is transmitted over the measurement data line. 4. The apparatus as set forth in claim 1, wherein: at least one of said first and second flowmeters is a Coriolis mass flowmeter/densimeter, or a Coriolis mass flowmeter/densimeter/viscometer. 5. The use of a meter according to claim 1 for mixing fluids having differing viscosities.
