Electromagnetic flowmeters can be used in almost all branches of industry for the measurement of liquids (with or without solids content)pulps, pastes and other fluids that have a specific minimum of electric conductivity. The measurement is based on Faraday's law of induction.

Superior electronics give you superior results - reliable and repeatable even under difficult process conditions, while quality manufacturing guarantee years of trouble-free use.

At KROHNE, all electromagnetic flowmeters are calibrated wet by direct comparison of volumes, the most accurate calibration method of all. The KROHNE calibration rig is the world's largest and most accurate.

3 x 100% diagnostics
OPTIFLUX overcomes the drawbacks of some SIL2-certified equipment:

  • detects errors unrecognised under SIL2
  • indicates erroneous results in the application (e.g. because of gas bubbles), which SIL2 cannot do
  • show up errors in accuracy and linearity, again unseen by SIL2

The 3 x 100% diagnostics in OPTIFLUX is, therefore, much better for you than a normal SIL2 certified meter.

OPTIFLUX – One for all applications
With just one signal converter and the widest range of flow sensors, the new OPTIFLUX cover 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.

This new concept marks a new era, and is the result of more than 40 years’ experience in electromagnetic flowmetering.

Sets new standards in electromagnetic flowmetering
Using brand new technology has enabled us to increase the measuring performance of OPTIFLUX 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. Here we exploited all known optimization potentials.

The new unique inbuilt diagnostics
The new inbuilt diagnostics not only fulfil the NAMUR guidelines, they exceed them by far. The new converter can check and detect whether it is still within its specifications or has been correctly installed. The 3 x 100% diagnostics consist of:

100% Applications Diagnostics
A working group led by NAMUR - consisting of representatives and users - analysed all measuring technologies. They defined for each one the application problems that an optimum meter would be able to detect.

The list highlighted here on the right shows those application problems, as well as some additional ones integrated into OPTIFLUX.

The indications given by OPTIFLUX together with a possible exclusion diagnosis by the user will certainly help you to conclude what the problem is in the application.

100% Out-of-spec Diagnostics
The OPTIFLUX checks periodically whether it is still working to within its specifications. The following is checked:

  • the accuracy by feeding in a test signal
  • the linearity of the meter
  • the accuracy of the field current used to generate the magnetic field

The test results can be viewed at any time using HART and KROHNE’s new PACTware tool, and a Verification Certificate can be printed out. There is no longer any need for time-consuming verification measurements.

100% Meter Diagnostics
Diagnostics normally refers to the meters diagnostics, which in the case of OPTIFLUX covers all these items:

  • Microprocessor test
  • Software test
  • Memory test
  • Electronics’ temperature test
  • Output tests for interruption, and the correct load
