Apparatus for mixing at least two fluids in a pulsating manner

An apparatus for mixing at least two fluids, comprising:

• a first fluid line for conducting an at least intermittently flowing first fluid and a second fluid line for conducting an at least intermittently flowing second fluid, the first and second fluid lines being connected at a junction to a third fluid line, which forwards the two, particularly mixed, fluids;
• 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;
• a first flowmeter, inserted in the first fluid line for measuring a volumetric flow rate and/or a mass flow rate of the first fluid and for generating at least a first measurement signal, representing the measured flow rate of the first fluid, and a second flowmeter, inserted in the second fluid line for measuring a volumetric flow rate and/or a mass flow rate of the second fluid and for generating at least a second measurement signal, representing the measured flow rate of the second fluid, with the first meter measuring at least intermittently a totalized volumetric or totalized mass flow rate of the first fluid and generating a, particularly digital, first measured flow rate value, which represents the totalized flow rate of the first fluid;
• and
• a first flow controller, which, using the first measurement signal, generates a first control signal, representing an instantaneous setting value for the first flow adjuster, and a second flow controller, which, using the second measurement signal, generates a second control signal, representing an instantaneous setting value for the second flow adjuster, said first and second flow controllers being connected by at least one measurement data line, and said second flow controller generating said second control signal for the second flow adjuster by also using the first measured flow rate value, which is transmitted over the measurement data line.
