The KROHNE OPTIFLUX 5000 electromagnetic flow sensor is accurate, 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 covers 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.
