SensoTech GmbH is a leading company in the field of process measurement technology based in Barleben, near Magdeburg, Germany. We develop and produce innovative solutions for monitoring and optimizing industrial processes. Our specialization lies in the precise measurement of concentrations, densities, and other parameters in liquids – in real-time and directly during the process.

Unlike optical methods, which are influenced by color or turbidity, conductivity-based methods, which are sensitive to electrical conductivity, or density-based methods, which can be disturbed by temperature or gas bubbles, our ultrasonic method is independent of these influences.

The LiquiSonic® measurement technology also contains neither moving parts nor components that can wear out or be consumed. Therefore, after installation, the measuring system is completely maintenance-free and drift-free.

The sensors offer digital signal transmission up to 1000 m and enable continuous inline measurement without sampling.

Our system uses ultrasonic transit time measurement to determine the sound speed in the liquid. The sound speed directly correlates with the water content and enables measurement accuracies of ±0.05 wt%. The integrated temperature compensation ensures stable results even with fluctuating process conditions.

With ketones like MEK, Karl Fischer titration leads to disturbing side reactions: ketal formation with methanol and bisulfite additions. These can cause both high and low measurement values. The ultrasonic technology from SensoTech completely avoids these chemical interferences.

Since the sound speed, like all other physical quantities, is influenced by temperature, all our LiquiSonic® sensors are equipped with temperature sensors. This allows the influence of temperature on the measurement to be directly compensated therefore, it is not necessary to integrate additional temperature sensors.

Our sensors operate reliably in a temperature range from -40 °C to 200 °C and pressures up to 500 barThrough various material options such as stainless steel, Hastelloy, or PFA coatings, aggressive media can also be measured. Ex protection for Zone 1 and 2 is also available.

Yes, our sensors are designed for extreme conditions. In addition to the extended temperature and pressure range, we offer custom adaptations such as sensor lengths up to 3000 mm, special alloys for corrosive media, and various protection types, including optional Ex protection. Each sensor is individually configured to your requirements configured.

Yes, by combining the speed of sound measurement with additional physical quantities (e.g., conductivity), up to 3 components can be determined simultaneously. This also allows monitoring of additional additives.

The system offers various digital interfaces (e.g., Profibus, Ethernet/IP, Foundation Fieldbus) as well as analog 4-20 mA outputs. The integration is seamless via standardized protocols.

Yes, SensoTech manufactures sensors individually according to customer requirementsAll standard flanges, any installation lengths (up to at least 1000 mm, further lengths on request), various threads, and special geometries for crystallization containers or small pipelines are available.

The system provides measurements in real time. Based on the measurements, you receive a current measurement value every secondThis fast response time enables effective process control and early detection of deviations.

The system is completely maintenance-free. There are no mechanical wear parts, seals, or optical windows that could be affected. Regular calibration is not required - the sensors remain stable for years.
