Electromagnetic sensors supplied by Krohne between 1975 and 2004 can be used without problem with the new Krohne IFC 300 converter. Krohne is thus the only supplier of electromagnetic flowmeters capable of retrofitting old sensors (which can date back as far as 1975) with the latest electronics. This means that Krohne customers can change over to a common converter, without having to shut down production in order to replace the tried-and-trusted sensors already installed in their pipework. It is even possible to incorporate, without problem, such modern communications technologies as HART, PACTware or Profibus DP. In most cases the original calibration settings can be migrated (in some cases back to 1978).
The IFC 300 is the latest converter for use with Optiflux electromagnetic flowmeters. With the IFC 300, Krohne has created a converter which, thanks to its high interference- and noise-suppression and diagnostic capabilities, is an attractive device for any user and of real benefit to plant. As nearly all the diagnostic functions of the IFC 300 are compatible with Krohne's tried-and-tested range of MID sensors, there is a corresponding increase in plant reliability and availability.
Not for custody transfer
Note that the old converter should not be replaced with the IFC 300 if the device is used in custody transfer. When using MID devices in explosion-hazard zones, check that the old converter can be replaced with the IFC 300.
The 3 x 100% diagnosis feature of the IFC 300 covers the normal device-diagnosis. Krohne is believed to be the first (and to date, only) supplier to augment these with a complete range of application-diagnosis functions, along with out-of-spec diagnosis to check for accuracy and linearity. The user can thus count on reliable information on the state of the device, the accuracy of its measurements and the presence of possible malfunctions. The 3 x 100% diagnosis feature allows the IFC 300 to achieve considerably higher reliability than other SIL2-certified devices, exceeding VDI/VDE/NAMUR-2650 specifications. When used with existing sensors, the new IFC 300 can perform all diagnostic functions, with the sole exceptions of flow-profile detection and linearity check. The Krohne IFC 300 can also be used with sensors from other manufacturers, allowing them to access the benefits offered by the IFC 300.
