3 Product description
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

Mounting Fermentation Monitor QWX43
12 Endress+Hauser
5 Mounting
If the measuring point is difficult to access, we recommend that you commission the
device in accordance with the commissioning instructions before installing it in the
tank.
5.1 Mounting requirements
Recommended mounting locations
• Compact version: On the side of the tank (horizontal orientation)
• Devices with pipe extension: From above (vertical orientation)
• Minimum distance of sensor tip to tank wall: 10 cm (3.94 inch)
• The measuring elements must be fully immersed in the medium
• The measuring elements should be in the bottom third of the tank but above the cone
for optimized measurement during fermentation
• Tanks with agitators: Align the tuning fork in the direction of flow parallel to the tank
wall
Avoid the following mounting locations
Mounting locations where a buildup of yeast or gas is likely to occur such as at the bottom
of the tank or near the filling limit for example
Pipes
• The device can be mounted in a pipe from a pipe diameter of 200 mm (7.87 in) to a flow
velocity of ≤2 m/s
• We do not recommend that the device be installed in pipes as the pipe wall is likely to
cause feedback effects on the measuring signal
• Please contact your Endress+Hauser representative for further information
