The LiquiSonic® inline analyzer of SensoTech
measures the concentration of cleaning and  anticorrosive agents or of acids and alkalis in various baths of different industries.
This allows an exact re-dosing.
For controlling bath changes, it is possible to determine the degree of contamination. If the limit is reached, a signal will be sent immediately. So the online bath monitoring leads to high product quality and increased plant capacity.
Furthermore, the resource efficiency
improves because the energy and raw material consumption reduces. The LiquiSonic® sensors can be integrated into any plant system and are installed in pipes from DN 10 or directly into the bath.
The sensor technology is based on sonic velocity measurement providing high measuring accuracy and the advantage of process capability, no maintenance and long lifetime. The measuring results will be updated every second and can be sent online to PCs and process control system.

Measuring of concentration or contamination degree
directly in the bath

Using analytical measuring technology in cleaning, rinsing, coating or treatment baths allows continuous monitoring of the bath concentration.

• In cleaning and degreasing baths the sensors measure the concentration of the cleaning agent,
• while in coating and plating baths, for example, an analysis of the anticorrosive agent is important.
• In pickling and etching baths, often acids and alkalis are used, so the measuring technology must be suitable for use in corrosive liquids.

The LiquiSonic® analyzer of SensoTech
is used successfully in both corrosive and non-corrosive process liquids. As standard, the sensors are made of stainless steel DIN 1.4571. For use in corrosive substances, special corrosion-resistant materials are available.

Because the concentration decreases
during the process course, the re-dosing can be controlled accurately by using the analyzer. So an optimal product quality and a low-cost, resource-efficient consumption are guaranteed. To control bath changes, the degree of contamination can be analyzed. If the limit is reached, a signal will be sent immediately. Thus, too early and too late bath changes can be avoided. This ensures a reliable cleaning result, improves facility capacity and reduces energy and raw material costs.

The LiquiSonic® technology is based on sonic velocity measurement providing high-precision and stable results updated every second. Sonic velocity meters are very robust and user-friendly.

The LiquiSonic® sensors measure the concentration ​​inline and provide the data online. The sensors can be integrated into any plant system and are installed in pipes from DN 10 or directly into the bath. The sensor impresses with process capability, no maintenance and long lifetime. In small plants, high ambient temperatures or having strong pipe vibrations, the electronic housing can be mounted separately from the sensor.

The LiquiSonic® controller displays the concentration values ​​
and saves all data. The trend view shows the process status at any time. On the PC, it is possible to read the measuring values ​​and to create reports. For automated process control, the measuring data can be sent ​​to the control system via 4-20 mA signal, Fieldbus (Profibus DP, Modbus), serial ports or Ethernet.

For 25 years SensoTech has been focused on the development, manufacturing and sales of inline analysis systems for process liquids. With worldwide installed, highly precise and innovative measuring systems for monitoring of concentrations, compositions and changes of chemicals as well as properties directly in the process, SensoTech has significantly contributed to the enhancement of the state of the art. In addition to the measurement of concentration and density, the phase interface detection as well as the monitoring of chemical reactions like polymerization and crystallization are typical applications. SensoTech inline analyzers set standards in the technological and qualitative valence, user friendliness and reproducibility of process values. Special calculation methods and sophisticated sensor technologies enable reliable and precise measuring results even under the most difficult process conditions.
The knowledge and the experiences of the highly motivated and committed SensoTech staff are the result of many different applications supported by well-known customers from the chemical and pharmaceutical industry, food technology, semiconductor technology, automotive and metal industry as well as many other industries. In addition, these experiences also open up unimagined solution possibilities for new measuring challenges.
