The QWX43 fermentation parameter monitor is mounted directly on the tank. It directly measures density, temperature and speed of sound and calculates all fermentation parameters, such as the degree of fermentation, residual extract and alcohol concentration. The multi-sensor system outputs high-precision, repeatable measurement results in real time. Install the Endress+Hauser Netilion app and monitor the fermentation process from any networked device.
Advantages
No on-site operation required
Precise, repeatable measurement results that replace manual sampling and laboratory analysis
Key process parameters are refreshed every minute, with measurement results available anytime, anywhere
Automatic notifications by comparing values of historical batches, optimizing and improving the process flow based on data
Automatic creation, saving and downloading of batches and values
Hygienic design, complete tank cleaning
Field of application
The QWX43 fermentation parameter monitor is a valuable assistant for brewers. It continuously measures and displays all important parameters of the beer fermentation process. The multi-sensor system outputs high-precision measured values, which the user can access anytime, anywhere after installing the app. It helps brewers fully understand the fermentation process and reduce follow-up work.
