The LiquiSonic analyser by SensoTech

The LiquiSonic analyser by SensoTech precisely measures with only one single sensor the sulfuric acid and oleum strength in the relevant concentration ranges.

Monitoring the sulfuric acid and oleum strength (wt%) inline, directly in the process, enhances safety and efficiency of production plants. The measuring results are available online and in real time. Due to the physical properties of sulfuric acid and oleum, the most suitable measuring method for determining the acid strength is sonic velocity measurement. Applications of the analyser include, for example, the acid production, alkylation, oil refining, syngas drying, fertiliser manufacturing, mineral processing or etching and pickling baths.

LiquiSonic technology is based on sonic velocity measurement providing clear and stable measuring results with an accuracy of up to 0.03 wt%. If the measuring values exceed or fall below critical process thresholds, a signal will be sent immediately ensuring timely countermeasures can be initiated. The real-time information significantly increases work environment safety and product quality and reduces costs caused by acid wastage and failed production.

Made of Hastelloy C-2000, the LiquiSonic sensor is absolutely resistant to corrosion.

The robust construction requires neither gaskets nor moving parts, so the sensor is maintenance-free with long-term stability. The installation is done directly into the existing pipe or vessel. The measuring results are updated every second, and for process automation the real-time data can be transferred to process control systems via 4-20 mA signal, digital outputs, fieldbus or ethernet.

The LiquiSonic controller displays and saves the measuring values. The analyser is delivered as a plug&play system, so a simple and fast commissioning is guaranteed.
