Liquitrend QMW43 clean-in-place process

The Liquitrend QMW43 has been designed to optimise the clean-in-place process by reducing the time and resources consumption at each cycle. The innovative, smart sensor from Endress+Hauser can measure the build-up and the conductivity in pipes and tanks, saving time by reducing manual inspections and cleaning cycles (which often includes safety margins due to critical installation points where the cleaning is challenging).

The use of flush installation and stainless steel (316L) replicates the same condition as the inner side of pipes and tanks and provides an effective figure about the build-up before and after the cleaning. This allows users to ensure that each cycle is never started too late or ended too soon by detecting even the thinnest layer of remaining product.

The device can also help to improve product quality by identifying not only chemicals but also distinguishing different products inside pipes without the need for visual inspections or lab analysis, preventing incorrect mixing and contamination.

The device offers analog outputs and IO-Link communication to allow complete documentation and traceability of the cleaning process, compliance with food safety standards, and full monitoring and control of cleaning operations.
