Introduction:

The RHOSONICS Series 9100 is only designed for the brewing industry for the main processes. Thanks to the innovative electronics and sensor design, continuous in-line monitoring of fluid mixtures is now possible with an extreme accuracy, virtually no maintenance and without moving or degrading parts.

The heart of the system is the cell, in which ultrasonic waves are being generated and received. This cell can be an externally mounted cell,  in a bypass, but may as well be a measuring section, where the liquid is analysed while flowing through the pipe. Several probe designs facilitate the measurement of concentrations inside tanks and processes of beer brewing.

Our analysers offer the following benefits:

Rhosonics introduced the new Plato Analyzer Model 9120 in July 2006, the ultimate system for fully automated inline analysis of beer (after fermentation). It offers the following distinct advantages, not found on any other Plato Analyzer available on the market.

1. Beer type specific calibration, based on a new, advanced calibration algorithm;
2. Batch calibrations are stored in memory, saving important labor costs;
3. Automatic calibration for drift, using advanced continuous correction method;
4. Automatic self test routine;
5. Graphic Touch Screen Display;
6. Trend Analysis;
7. PLC control for switching of calibrations

1. Beer type specific calibrations.
With the Model 9120 Plato analyzer, it is no longer necessary to calibrate the analyzer for specific beer types. In addition, it is not even necessary to send samples to the factory, as is the case with other analyzers for Plato analysis.
Other Plato analyzers use a standard calibration curve, which can only be adapted in a limited way to specific beer types. When the fermentation degree of the beer is significantly different, the built-in calibration and temperature correction does not match with the real situation for that beer type. To overcome this problem, equipment vendors ask samples so that a specific calibration can be made only suitable for that specific beer type.
The Model 9120 however, allows you to easily enter the data about your beer types, such as the fermentation degree, for each beer type you wish to measure inline. This information is used by the analyzer to automatically adopt its advanced algorithm that is used to calculate the concentration from sound velocity and temperature data. The Rhosonics Plato analyser can store 255 different beer types. As beer specific data is stored per beer type, tedious and time consuming calibrations for each product change are no longer necessary. Per beer type, you store the name, the beer specific data, as well as the alarm trip p°Points. Upon each product change, the system automatically recalls the previously stored calibration data.
When you switch the calibration to a specific beer type that you stored previously, the analyzer automatically adapts the calibration curve and temperature correction, greatly improving the accuracy of the Plato analysis, and eliminating the need for special and expensive calibrations by the equipment vendor.

2. Batch calibrations are stored in memory
When you detect small deviations with the laboratory results of a field grabbed sample, the Model 9120 allows you to easily correct its calibration. In addition, this information is stored as well in the built-in beer specific database, making this calibration only necessary once for each beer type.

3. Automatic system calibration
Other equipment vendors require frequent recalibration of the system, some even every day. The ultrasonic sensor of the Model 9120 is automatically monitored during the inline analysis, while a unique and proprietary method eliminates system drift. This calibration, which is normally done in the factory as part of the final calibration procedure, is now performed automatically and continuously, without operator actions. The results are considerable savings on maintenance costs, and increased accuracy of the inline analysis.
Another calibration which can be performed automatically, is the zero calibration (water calibration). Previously, this calibration had to be performed by an operator, while water was running through the pipe. With Model 9120, the system can be remotely given a command to perform the calibration. When the remote liquid selection option is used, liquid number zero forces the analyzer to calibrate itself, adjusting the necessary parameters fully automatically. This feature provides additional savings on maintenance costs, and because the analyzer carefully checks all parameters that can affect this calibration, the zero point calibration is realized with the same accuracy as a well performed manual calibration in the laboratory.

4. Automatic self test routines
Of course the Model 9120 Plato analyzer checks the integrity of its components, as well as unusual occurrences in the process. For instance, the presence of gas bubbles due to imperfect CO2­­ dosing, are flawlessly detected and ignored, improving the entigrity and continuity of the analysis result.

5. Graphic Touch Screen Display
Thanks to a water and shock proof Touch Screen, the control of the analyzer is greatly simplified. In contrast with other systems, the small arrow buttons and complex menu navigation is replaced by easy to recognize, context dependant icons, pop-up screens with additional information and pop-up key-pads for direct entry of numbers and letters. A manual is rarely needed and the time to learn the system and its menu structure is shortened greatly.

6. Trend analysis
Besides a user configurable display, the Model 9120 offers you the possibility of displaying concentration and temperature trends, providing additional on-the-spot information.

7. PLC control
Model 9120 can be fully integrated in automated beer production environments.
The stored calibration can be activated, using a binary code, which can normally be generated by PLC systems, or through the built-in RS-232 serial communication port.
