An assembly mixes two liquids. Each liquid is delivered via its respective tube with a flow-regulation unit and flow meter, and is surrendered at a junction to a third tube. Each flow-regulation unit is linked via a databus to a joint flow-regulation programmable logic control. An independent claim is also included for the operation, in which the first fluid F1 is admitted to the tube (L1) and thence to the third tube (L3). The rate of mass- or volume-flow is registered as a first signal m1 to calculate a representative total flow value Q1, and used to calculate a target flow-value for the second fluid F2. The second fluid is then admitted to the second tube (L2) and the target mass or volume of the second fluid is then discharged to the third tube (L3). |
