A conductivity meter designed especially for CIP systems

| By Chemical Engineering



The CombiLyz conductivity meter (photo), with an accuracy of±1% and a measuring range of 500µS/cm to 1,000 mS/cm, together with robust temperature compensation, provides many important features for clean-in-place (CIP) systems. Where CIP systems require acids or alkalis, accurate measurement of concentration levels is essential. While the concentration of the acid or alkali is increasing, the conductivity meter controls the specified concentration of the relevant cleaning media. The meter’s precise measurements ensure that no excess chemicals are used. During the phase separation in the CIP return flow, the CombiLyz quickly recognizes different media, even when temperatures fluctuate significantly, helping to reduce the loss of stored cleaning agents. After one cleaning cycle, the CombiLyz accurately measures the concentration of the remaining chemicals in the rinse water. With this information, the programmable logic controller (PLC) can control the predefined media circuits using valve nodes, reducing the risk of contamination by residual chemicals. A compact design reduces flow resistance in the process line, and deposits and impurities can be easily flushed out of the system. — Baumer Ltd., Swindon, U.K.
