OPTIFLUX 4000
1.1 The all-round solution for process industries
The OPTIFLUX 4000
OPTIFLUX 4000 design meets the demands of a very wide range of applications in industries
OPTIFLUX 4000OPTIFLUX 4000
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 the OPTIFLUX 4000 can offer a solution.
Examples include water injection under high pressures (2500 lbs), sub-sea installations, slurries
with very high solids contents, alkaline solutions and acids, up to chemical dosing, bleaching,
colouring, 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, OPTIFLUX 4000 has a wide range of certifications including
OIML R49 & R117, MI-001, MI-004 & MI-005.

version. The chambers can even be completely
surpassed if the IP68 version is combined with our
special subsoil coating, allowing the OPTIFLUX 4000
to be installed directly in the ground.

1.3 Measuring principle
An electrically conductive fluid flows inside an electrically insulated pipe through a magnetic
field. This magnetic field is generated by a current, flowing through a pair of field coils.
Inside of the fluid, a voltage U is generated:
U = v * k * B * D
U = v * k * B * D
U = v * k * B * DU = v * k * B * D
in which:
v = mean flow velocity
k = factor correcting for geometry
B = magnetic field strength
D = inner diameter of flowmeter
The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v
and thus the flow rate Q. A signal converter is used to amplify the signal voltage, filter it and
convert it into signals for totalizing, recording and output processing.
