FEM630 | ELECTROMAGNETIC FLOWMETER  |  OI/FEM630-EN REV. A
Intended use
This device is intended for the following uses:
•  For the transmission of fluid, pulpy or pasty measuring 
media with electrical conductivity.
•  For volume flow measurement (in operating conditions).
•  For mass flow measurement (based on a non-adjustable 
density value).
The device has been designed for use exclusively within the 
technical limit values indicated on the identification plate and 
in the data sheets.
When using measuring media, the following points must be 
observed:
•  Wetted parts such as measuring electrodes, liner, 
grounding electrodes, grounding plates or protection 
plates must not be damaged by the chemical and physical 
properties of the measuring medium during the 
operating time.
•  Measuring media with unknown properties or abrasive 
measuring media may only be used if the operator is able 
to perform regular and suitable tests to ensure the safe 
condition of the device
•  The indications on the name plate must be observed
•  Before use of corrosive or abrasive measuring media, the 
operator must clarify the level of resistance of wetted 
parts.
ABB will gladly support you in the selection, but cannot 
accept any liability in doing so.
Improper use
The following are considered to be instances of improper use 
of the device:
•  Operation as a flexible compensating adapter in piping, 
for example for compensating pipe offsets, pipe 
vibrations, pipe expansions, etc.
•  For use as a climbing aid, for example for mounting 
purposes.
•  For use as a bracket for external loads, for example as a 
support for piping, etc.
•  Material application, for example by painting over the 
housing, name plate or welding/soldering on parts.
•  Material removal, for example by spot drilling the 
housing.
Use in Potentially Explosive Atmospheres
Note
•  An additional document with Ex safety instructions is 
available for measuring systems that are used in 
potentially explosive atmospheres.
•  Ex safety instructions are an integral part of this manual. 
As a result, it is crucial that the installation guidelines and 
connection values it lists are also observed. 
The icon on the name plate indicates the following:
