LEWA smart control: The compact controller for multiple applications System screen pump: selection of operating mode Comparison: control behaviour of PID controllers to LEWA smart control input of desired value actual value actual value smart control With LEWA smart control the adjustment of the actual value at process start-up reaches a maximum deviation of about +/- 1% after 30 seconds already Due to the saved characteristic curve of the LEWA pump, LEWA smart control ensures a fast adjustment to the desired value within the shortest possible time LEWA offers a controller for the optimum monitoring...

Fluid metering Variant 1: basic version minimum design, one pump, without electric stroke adjustment two pumps, two electric stroke adjustments Examples where the operator gets maximum benefit from LEWA smart control: Controlling the metering flow: If the process requires to maintain a continuous mass or volumetric flow, this flow has to be controlled flexibly and reliably, for example by injecting blowing agents during extrusion pro- cesses. Here, the speed of the extruder is the guide value for the dia- phragm metering pump. Using LEWA smart control, the blowing agent can extruder speed into...
