Bath monitoring

Continuous real-time monitoring

LiquiSonic® analyzers monitor online and in real-time bath parameters such as concentration, temperature and contamination degree in all common industrial surface treatment and cleaning processes. The sensor is installed either directly in the bath or in the pipe from DN 6 (NPS 1/8").

Advantages of bath monitoring

  • bath process documentation as an indirect proof of compliance with the relevant quality parameters "bath concentration" and "bath temperature"
  • perfect bath care by optimum re-dosing of the cleaning agent, solvent or other process liquid in order to compensate losses of process liquid and water resulting from evaporation and discharge
  • efficient control of bath changes by inline monitoring of the bath contamination degree

Applications of LiquiSonic®

Typical applications include:

  • cleaning, degreasing and rinsing baths,
  • corrosion prevention, preservation and coating baths,
  • quenching baths,
  • pickling and etching baths,
  • treatment baths.

The LiquiSonic® sensors measure precisely, continuously and directly in the process the concentration of, for example,

  • cleaning agents and solvents,
  • anti-corrosive agents and preservatives,
  • polymers, liquid metals and pigments,
  • acids and bases,
  • oil emulsions.

The use of cleaning and treatment baths is common in various industries and processes. For example, single or multi-chamber systems or conveyor systems are used to remove film or particulate impurities or to apply anti-corrosion liquids.

All technologies are realized within single or cascaded baths. The following process figure demonstrates the application of LiquiSonic® at relevant measuring points of a degreasing cascade.
