1.3  Intended use 
This device is intended for the following uses: 
—  To transmit fluid, pulpy or pasty measurement media with 
electrical conductivity. 
—  For volume flow measurement (under operating 
conditions). 
—  For mass flow measurement (based on a fixed density to 
be programmed). 
 
The device has been designed for use exclusively within the 
technical limit values indicated on the identification plate and 
in the data sheets. 
 
In terms of the measuring medium, observe following points: 
—  Wetted parts such as measuring electrodes, liner, 
grounding electrodes, grounding rings, protection flanges 
must not be damaged because of the chemical and 
physical characteristic of the measuring medium. 
—  Media with unknown properties or abrasive measuring 
media may only be used if regular and suitable tests can 
be performed to ensure the safe condition of the device. 
—  The information on the name plate must be observed. 
—  Prior to using corrosive and abrasive measurement media, 
the operator must check the level of resistance of all parts 
coming into contact with the measuring medium. 
  ABB will gladly support you in selecting the materials, but 
cannot accept any liability in doing so. 
 
1.4  Improper use 
The following are considered to be instances of improper use 
of the device: 
—  For operating as a flexible adapter in piping, e.g. for 
compensating pipe offsets, pipe vibrations, pipe 
expansions, etc. 
—  For use as a climbing aid, e.g. for mounting purposes 
—  For use as a support for external loads, e.g. as a support 
for piping, etc. 
—  Material application, e.g. by painting over the name plate 
or welding/soldering on parts 
—  Material removal, e.g. by spot drilling the housing 
 
1.5  Warranty provisions 
Using the device in a manner that does not fall within the 
scope of its intended use, disregarding this manual, using 
underqualified personnel, or making unauthorized alterations 
releases the manufacturer from liability for any resulting 
damage. This renders the manufacturer's warranty null and 
void.
