LEWA metering and mixing systems — Components Perfect controller: LEWA smart control Performance overview Pump types with usable discharge pressure up to 1,200 bar Flow rate * depending on the type and boundary conditions Desired value Exact adjustment: via the stroke length and/or speed Precision right from the beginning: LEWA metering pumps or a suitable alternative Monitored metered flow: Different flow meters can be use

LEWA metering and mixing systems — Components The most important components for cost-effectiveness and safety. The compact controller LEWA smart control For optimum monitoring of metering systems, we provide the LEWA smart control, which has been developed specifically for this reason: – The software allows you to store the characteristic curve of the pump, including the error spectrum and control range. – The programmed adaption function – the adaptive control – ensures that the actual value is adjusted quickly without causing substantial transient oscillation that is common in...

LEWA metering and mixing systems — Components Continued: LEWA smart control The following expansions are available: – pgrade to bus communication (e.g. Profibus-DP, Profinet, U Ethernet, Modbus TCP-IP) – arger touch panel (optional also for use in potentially L explosive zones I and II) – odular expansion to a second metering line and/or to the electric M stroke adjustment (EHV) to expand the adjustment range – onitoring of additional parameters (e.g. fill level, conductivity) M using additional sensors – n case of more control loops: Expansion to a larger control system I with the same...

LEWA metering and mixing systems — Components The pump is the heart of the LEWA system. We prefer using diaphragm metering pumps from our own production. These provide: – Continuous adjustment of stroke length and frequency, ensuring an accurate and wide adjustment range – Pressure has virtually no influence on the pumping characteristics, which makes monitoring easy and precise – High metering accuracy paired with flow measurement/monitoring ensures reliable and reproducible production Flow meters measure the volume flow or mass flow and transmit the measured actual value to the...
