Measuring liquid concentration or density in-line is important in the chemical industry as density variations have impact on both raw materials and finished products. Process safety is also mandatory, since hazardous chemicals represent a potential risk to people and the environment. While managing these challenges, chemical manufacturers strive to produce high-quality products that meet customers’ specifications. To achieve these goals, accurate process measurements, high process efficiency, low energy consumption, and state-of-the-art process control management are crucial.
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
