3.1 Measuring principle
The Fermentation Monitor QWX43 is a measuring device for monitoring temperature,
density, viscosity and sound velocity. It is specifically intended for monitoring the
concentration of sugar, alcohol and the brewing process during the fermentation of beer,
for example.
The measurement method is based on a combination of the vibronic principle with an
integrated temperature measurement and a sound velocity measurement using
ultrasound. The compact device is installed directly in the tank and is powered by a
separate supply voltage. The IP66/67-rated housing contains a WLAN connection which
transmits the sensor measured values to the Endress+Hauser Netilion Cloud. The values
can be called up and saved via Netilion Value.
3.2 System design
The Fermentation Monitor QWX43 can be put into operation with the following digital
