Depending on the configuration, the SONEM sensor technology allows the generation of a multifrequency ultrasonic signal over a wide frequency band (MHz range). Due to the high resolution of the sensor system, in combination with SONEM Analytics, detailed information about the media to be characterized can be obtained.
Due to different ultrasonic resistances of two liquids, a partial reflection occurs at the interface of both. The greater the impedance difference of the liquids, the greater the reflected portion of the signal.
As soon as the ultrasonic signal hits molecules, they are deflected from their rest position. The dispersion effect is caused by the characteristic ultrasonic properties of each medium. Consequently, each medium reacts individually to an ultrasonic signal and thus generates substance- and frequenzy-specific ultrasonic speeds. Hence, conclusions can be drawn about the medium.
Speed of sound
Depending on the predominant molecular bond, each substance has a specific speed of sound.
The received ultrasonic signal is measured for various physical properties, such as transit time. The high precision results in a resolution of
Monitoring Analysis Optimization Development
The generated data set is evaluated and further processed with the AI algorithms of SONEM Analytics. The result is the SONEM “fingerprint”! A unique, detailed data set that allows monitoring and quality control of a medium. This “fingerprint” can be used to enable quality assurance across different batches and locations.
Comparative measurement procedure
SONEM sensors are basically designed as a comparative measuring method. The great advantage here is that relevant individual values do not have to be defined and monitored in a multi-stage procedure. It is sufficient to define a reference medium which fulfills the required properties. After this medium has been measured, a target corridor can then be defined and substance changes of any form can be monitored.
SONEM measures and analyzes media in real time. Thanks to powerful hardware, SONEM Analytics’ AI algorithms and cloud infrastructure, all evaluations are performed as quickly as possible. Customers can thus access the required process information live and initiate any adjustments without delay. The detour via more time-consuming analysis technology can thus be avoided in many cases.
The link between SONEM’s powerful hardware and SONEM Analytics allows the detection of the finest differences. With the help of the high resolution, deviations in the low ppm range can be detected. In various branches of the process industry, relevant product changes can thus be detected at an early stage and processes can be optimally controlled.
Non-invasive measuring system
Depending on the configuration, the SONEM Liquid Analyzer can be used as a non-invasive sensor in the production process. Due to the space-saving design and the absence of constructive elements protruding into the product line, the SONEM sensor technology is suitable for hygienically sensitive processes such as processes in the food industry.
All SONEM sensors have been designed to be utilizable in as many industries and applications as possible. For this reason, the hardware and frequency range have been selected so that different mediums and viscosities can be detected and measured. This flexibility allows our customer to utilize our sensors in various process steps, while avoiding several versions and systems.
No costly and time-consuming infrastructure modifications are necessary to integrate SONEM sensors into your process. Rather, the sensor can be integrated directly into the existing piping system, the only requirement being a type N process connection.
