In the steel production, the LiquiSonic® measuring technology is used in numerous process levels to optimize operations. With this technology it is possible to save process chemicals, such as acids and cooling lubricants without influencing the surface finish negatively. Thus, the online measuring technology ensures a permanent and consistently high quality of products.

The sonic velocity analyzer LiquiSonic® is uselful for many applications in the metal industry:

  • concentration measurement in pickling baths
  • concentration measurement of rolling and cutting oil emulsions
  • acid regeneration
  • electrolytic galvanizing
  • roller chrome plating

SensoTech analyzers are ideal instruments for the rugged process conditions encountered in the metal and mining industries. The sensors allow precise control and accurate measurements, despite extreme temperatures, pressure and other harsh environments.

Unbeatable utilization rates 
Where accuracy is critical, or where high pressure, high temperatures or sensitive processing environments make sampling impractical or impossible, SensoTech analyzers are ideal for monitoring inline processes. 
LiquiSonic® sensors are engineered for tough industrial processes including Class I Division 1 Hazardous Area installations. 

A rugged housing is crucial for protection and high mechanical stability. Depending on the sensor type, our housings are able to withstand temperatures up to 200 °C or 392 °F, rated pressures up to 500 bar or 7,250 psi and are resistant to lye, acids and solvents. LiquiSonic® allows automated manual operations and achieve a new level of productivity and process control.

The fundamentals for this quality are the high-grade materials used such as stainless steel, PTFE and PFA, alloy steels or tantalum. The sensor design consists of one homogenous body and requires no gaskets.

Well connected
Our sensors may be equipped with all common process adapters and fittings and can be used under the most complex application conditions. By changing immersion lengths or process adapters, our sensors fit into tanks and vessels of almost every design as well as directly in any size tube. Because the measuring technology is not dependent on color, turbidity or other optical attributes, the user will have no limitations, even under the most challenging application conditions.

Products and process may change
LiquiSonic® systems can easily be adapted to accommodate various modified process conditions. The Controller software manages up to 256 various product characteristics. Depending on the user access rights, these characteristics may be activated after the sensor replacement or when process conditions change. This concept ensures the return on investment, and decrease the response time on changing boundary conditions. For new applications, a complete new calculation model can be created by using process reference values.

Individual interfaces 
SensoTech is able to offer all current and emerging standards of signal processing. For continuous concentration and density measurement, 4 … 20 mA in 2-wire loop powered or 4-wire technology, Profibus PA, Foundation Fieldbus, Modbus or Ethernet are available. For alarm level detection and switching a non-contact output or a digital output can be configured. SensoTech analyzers can always match installation needs.
