The wort boiling takes place either inside the wort kettle (internal boiler) or externally with an external boiler, which can be designed as a shell and tube or plate heat exchanger. The boiling times per batch are between 50 and 75 minutes. Goals of wort boiling:
- Setting the desired wort concentration
- Destruction of malt enzymes or fixation of the wort composition
- Sterilization of the wort
- Protein coagulation
- Hop isomerization
- Aroma formation
- Evaporation of unwanted aromatic substances
For quality and efficiency reasons, the wort concentration in the brewhouse must be continuously monitored.
LiquiSonic® Sound velocity measurement in the wort boiler
Application
The LiquiSonic® Plato system determines the original gravity at different stages of the brewing process. In the wort kettle, the LiquiSonic® Plato system is used for:
- Control of the boiling process
- Determination of the concentration of the casting wort
The immersion sensor is made entirely of stainless steel and operates maintenance-free, drift-free, and long-term stable due to its robust construction. The integrated LiquiSonic® high-performance technology enables stable measurement even with gas bubble content. Through the LiquiSonic® controller automatic product switching is possible. An internal limit monitoring signals exceedances and shortfalls and sends real-time information via analog or digital outputs, serial interfaces, or fieldbus (Profibus DP, Modbus) to the process control system.
Installation
In the internal boiler, the sensor is mounted directly in the wort kettle. The installation length is variable and can be up to 3 m. A special design of the sensor minimizes the influence of deposits. Additionally, the sensor in the internal boiler can be equipped with a cleaning head to prevent crusting from foam. When used in an external boiler, the sensor is mounted directly in the circulation line between the wort feed pump and the heat exchanger. During the installation of the LiquiSonic® Sensors no bypass is necessary and dead spaces are avoided.
The LiquiSonic® Controller 30 can be connected with up to 4 sensors. In addition, up to 99 types of beer can be stored with the corresponding calculation models. This makes it possible to monitor several measuring points simultaneously.

Customer benefits
LiquiSonic®reduces time-consuming laboratory measurements and makes manual sampling unnecessary:
- Time required: 2 hours per day
By continuously determining the wort, the cooking time can be shortened.
LiquiSonic® Plato ensures precise analysis of the original gravity concentration with permanent data recording. The system is used in both internal and external boilers. No expensive bypass solutions are necessary.
