Automated processes High operational safety: from minute to high volume flows Precise, reliable and economical: LEWA metering pumps Plausibility check as safety aspect The most basic metering system is a metering pump monitored by a flow meter. Optimum monitoring for this system however is provided by the controller LEWA smart control which was specially developed for such duties. It compares the adjusting value of the metering pump and the measuring signal of the flow meter and checks them for plausibility. Each deviation is recorded and signalled both signals failing at the same time is...
