Based on systematically collected experience with flow controlled metering systems, LEWA designed a controller that meets all the important requirements on the "brain" of metering systems.
The control unit continually compares the flow rates (using a flow meter) with the target values (defined by the user or via PCS).
If there are deviations from this continuous plausibility test, corrective measures are implemented. Since the controller saves the characteristic curves of different pumps, deviations without significant overshooting can be controlled faster and more precisely.
Maximum installation: Two pumps and two electric stroke adjustments.
