In-line measurement of liquid concentration and density directly in chemical process

Vaisala K-PATENTS® process refractometer is designed to measure and indicate inline liquid concentration of almost any chemical or compound.

The refractometer can be installed cost-efficiently in the main processing line, bypass line or vessel to control the raw and in-process materials in order to extract their maximum value and achieve high quality end products. The performance of all types of chemical refining, manufacturing, and quality-control operations can be dramatically improved with Vaisala’s refractive index measurement technology – whether they are in continuous or batch processes. 

Unlike intermittent sampling, continuous monitoring provides instant feedback on changes in the process, and this data can enable real-time and precise process control of the common chemical industry operations, e.g.:

  • Reactor, reaction degree, and endpoint determination
  • Evaporation
  • Dissolving tank or vessel
  • Dilution, mixing or blending
  • Solid-liquid extraction
  • Absorbers and wet scrubbers
  • Ion exchangers
  • Distillation
  • Interface detection and product identification of product-to-product interfaces in loading/ unloading
  • Quality control

Using the Vaisala concentration measurement technique and its easy integration into plant engineering systems enables significant improvements in the plant capacity, the process safety or product yields.

Refractive index technique designed for harsh chemical environments and applications

Vaisala K-PATENTS® process refractometer offers accuracy, repeatability and reliability even in the most extreme environments that can be corrosive or abrasive, subject to chemically aggressive solutions, extreme temperatures, pressures, vibration or contamination, humidity and dust, or any combinations of these factors.

  • Designed to Pressure Equipment Directive PED 97/23/EC and ASME Section VIII Division 1 - Pressure Vessels
  • Selection of different IP codes (IEC 60529) and NEMA ratings that withstand various harsh conditions and outside use.
  • Special wetted parts materials ranging from stainless steel and higher alloys to PFCF or PTFE (Teflon®) for harsh environments and chemically aggressive process fluids.
  • Intrinsically safe and hazardous area certification for hazardous areas
