The accurate KROHNE OPTIFLUX 5000 electromagnetic flow sensor is hard-wearing and robust. This is
the result of a special flow tube design with conical parts, which streamlines distorted flow profiles.
Leading test institutes use the KROHNE OPTIFLUX 5000 electromagnetic flow sensor as their master meter.
3×100% Diagnostics
The KROHNE OPTIFLUX 5000 electromagnetic flow sensor overcomes the drawbacks of some SIL2-certified
equipment:
Detects errors unrecognized under SIL2
Indicates erroneous results in the application (e.g. because of gas bubbles), which SIL2 cannot do
Corrects errors in accuracy and linearity, again unseen by SIL2
The 3×100% diagnostics in the KROHNE Optiflux 5000 electromagnetic flow sensor is, therefore, much better
for you than a normal SIL2 certified meter.
The KROHNE OPTIFLUX 5000 Electromagnetic Flow Sensor – One For All Applications
With just one signal converter and the widest range of flow sensors, the KROHNE OPTIFLUX 5000
electromagnetic flow sensor overs all applications, from a simple water measurement to corrosive or
abrasive products or even pulp in the paper industry. Simplified engineering, procurement, and
inventory lead to cost-savings for the user.
Sets New Standards in Electromagnetic Flowmetering
Using brand new technology has enabled us to increase the measuring performance of the KROHNE Optiflux
5000 electromagnetic flow sensor even further. These improvements are particularly useful where today's
meters begin to capitulate. Examples of this include very low conductivity, measurement of rapid product
changes with corresponding changes in pH, or the measurement of pulp in the paper industry. This increase
in performance was possible by a 30-fold improvement in the measuring technology components.
Operating Principle
Magnetic flow meters are intended to measure the flow of electrically conductive liquids in full pipes.
The pressure drop through the meter is minimal, (equal in magnitude to a piece of pipe of the same diameter
and length) making it an excellent choice for low pressure systems. There are no moving parts or
obstructions in the fluid stream so the meter is virtually maintenance free and suitable for fluids
containing abrasives. Modern pulsed DC excitation eliminates problems with zero shift often found in other
designs.
The detection of flow is accomplished using the principle of electromagnetic induction. As a conductor passes
through a magnetic field, a voltage is generated that is proportional to the velocity of the conductor moving
through the field. In the case of the magnetic flow meter, the conductor is a conducting liquid. The higher
the flow rate the greater the generated voltage.
Grounding Rings
For process flow measurement reasons the product must be grounded. Such a grounding system is lacking in pipes
upstream and downstream of the primary head which feature a corrosion-resistant internal coating or liner, or
are made entirely of plastics material. In such cases, grounding rings must be fitted on both sides of the
primary head. Consult us for further information.
