Installation, operation, maintenance and servicing
must be performed:
• by suitably trained personnel only
• in accordance with the information provided in
this manual
• in accordance with relevant national and local
regulations
Intended use
This sensor is intended for the following uses:
• To measure the volumetric flow rate, flow velocity, volume
flow (forward, reverse and net) and pressure (option) of a
conductive fluid.
The sensor 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 by the chemical and physical
characteristic of the measuring medium.
• The information on the name plate must be observed.
Improper use
The following are considered to be instances of improper use of
the sensor:
• For operating as a flexible adapter in piping – for example,
compensating pipe offsets, pipe vibrations, pipe
expansions.
• For use as a climbing aid – for example, for mounting
purposes.
• For use as a support – for example, external loads or as a
support for piping.
• Material application – for example, by painting over the
nameplate or welding / soldering on parts.
• Material removal – for example, by spot drilling the
housing.
