The all-round solution for process industries

Electromagnetic flowmeter OPTIFLUX 4000 Sensor

  • Robust, fully welded construction
  • Standard solutions for the widest range of industrial applications
  • Engineered solutions for very demanding applications

The OPTIFLUX 4000 design meets the demands of a very wide range of applications in industries including the chemical, pulp & paper, water and wastewater, minerals and mining, iron, steel and metals, pharmaceuticals and oil & gas industry. 

The OPTIFLUX 4000 has a field proven and unsurpassed lifetime. This is assured by the fully welded construction, full bore pipe construction, absence of moving parts and wear resistant liner materials. Even for demanding applications in harsh environments or with aggressive and abrasive media KROHNE’s OPTIFLUX 4000 can offer a solution. 

Examples include water injection under high pressures (2500lbs), subsea installations, slurries with very high solids contents, alkaline solutions and acids, up to chemical dosing, bleaching, coloring, and black liquor in the paper industry. If required, a solution beyond our standard scope can be engineered. KROHNE has in house specialized know how on constructions, welding and exotic materials.

For custody transfer applications, where the highest accuracy is crucial, OPTIFLUX 4000 has a wide range of certifications including OIML R49 & R117, MI-001 & MI-005.
