Chemical industry
Aggressive, viscous and abrasive media are everyday conditions for instruments in chemical plants. RETTAR's non-contact radar technology and wear-resistant designs keep measuring where contact sensors fail quickly.
Typical applications and solutions
Level control in tanks with aggressive liquids
Continuous level measurement of acids, alkalis and solvents in storage tanks without the sensing element contacting the medium.
Measurement challenges
Chemically aggressive medium, vapors and foam on the surface, varying tank geometry.
Solution
CFR6400 integrated radar level meter for liquids
Flow and density control of process solutions
Accurate flow and density control of reagents and process solutions stabilizes the process and reduces chemical consumption.
Measurement challenges
Flow subject to significant fluctuation, highly aggressive medium, possible suspended particles.
Solution
Density meter + acoustic flowmeter / electromagnetic flowmeter
Interface level in separators and settlers
Accurately locating the interface between layers (water/organics, sludge/overflow) optimizes the separation process and reagent dosing.
Measurement challenges
Unstable medium composition, need for wear and corrosion resistance, continuous high-precision measurement.
Solution
SLD1100 interface level meter + electromagnetic flowmeter
3D monitoring of bulk chemical raw material silos
For granular and powdered raw materials (polymers, salts, mineral components), 3D scanning provides an accurate volume and mass of stock on hand.
Measurement challenges
Dust during loading, multiple signal reflections from the material, dynamically changing pile shape.
Solution
3DPro2300 radar 3D scanner
Pipelines and sumps for process slurries
Transporting slurry through pipelines and accumulating it in sumps requires reliable level and flow control under wear and corrosion.
Measurement challenges
High viscosity and abrasiveness of the medium, strong interference for contact instruments.
Solution
Density meter + radar level meter + electromagnetic/acoustic flowmeter
