1 MagCheck introduction
1.1 Introduction
MagCheck is an all-round portable testing and verification device for KROHNE electromagnetic
flowmeters, enabling a complete functionality and accuracy verification of the EMF without taking
the meter out of the pipeline nor interrupting the process. MagCheck measures autonomously and
can be used on KROHNE EMF-converters (not on Ex-converters!). MagCheck can be employed
either as an automatic verification instrument or as a manual flow signal calibrator, depending on
the converter type.
MagCheck is used for precise analysis and verification of magnetic flowmeters. Precision of these
meters is not only a function of accuracy of electric data, but also depends on the mechanical
installation of flowhead and converter. Faulty installation, both mechanical or electrical, may not be
detected by MagCheck.
Use of MagCheck on converters, which are not listed as compatible may cause
damage to these converters, to MagCheck and in case of connection to hazardous
area versions of these converters damage to protective elements!
MagCheck can and must NOT be used on:
•
TIV 50, TIV 60
•
K300, F200
•
SC150
•
ALTOFLUX 2W, IFC 040
•
IFC 090i
•
TIDALFLUX*
•
CAPAFLUX, IFC 090 K / CAP
•
NB 900 Power Booster
•
Any Ex Zone 1/div 1 versions (hazardous area versions) of
ALTOFLUX 2W, IFC 040; SC80A / AS, SC100A / AS;
IFC 080, IFC 200, IFC 200 E; IFC 090, IFC 090i; IFC 110;
IFC 210 Ex versions!
*) Verification of the conventional electromagnetic flowmeter part of TIDALFLUX IFM 4110 PF is
possible after disabling the level input to IFC 110 PF. This will allow for a statement of flow velocity
measurement part, not of total the performance of TIDALFLUX.
1.2 MagCheck as automatic verificator for KROHNE IMoCom converters
MagCheck is able to perform a fully automatic verification on magnetic flowmeters in combination
with these converters. In this mode accuracy of the converter and all electric data of the primary
head are verified which are vital for their function and accuracy. During the fully automatic test run
the display will indicate all measured data. MagCheck reads and stores all settings of the IMoCom
converter and all measured data of up to 70 meters.
MagCheck can verify KROHNE electromagnetic flowmeters with following IMoCom signal
converters:
•
IFC 010
•
IFC 020
•
IFC 090 Non-Ex versions
•
IFC 110 Non-Ex and non TIDALFLUX-versions only
•
IFC 210 Non-Ex versions
Data may be downloaded onto a PC (Microsoft Windows 95, 98, 2000, NT) using the KROHNE
MagCheck PC-program. After downloading data into the PC the related memory areas in the
MagCheck are cleared and can be used for further measurements. The KROHNE MagCheck PC-
program evaluates the downloaded data. If all data are within their limits, the program will create a
final certificate confirming the meter operates with an accuracy deviation of less then 1% related to
reference conditions. If the evaluation shows data exceeding their limits, the certificate will state,
that the meter is not working properly.
