4.3 Installation at high media temperatures
> 150°C (302°F)
At high media temperatures > 150°C (302 F) the flowmeter sensor
must be installed so that the transmitter is pointing to the side or
downward (see the figure below).

4.4 Installation for pressure and temperature
measurement
As an option, the flowmeter can be fitted with a Pt100 for direct
temperature measurement. This temperature measurement supports,
for example, the monitoring of the media temperature or the direct
measurement of saturated steam in mass flow units.
If pressure and temperature are to be compensated externally (e.g.
with the "Sensycal"), the measuring points must be installed as
illustrated in the figure below.

4.5 Installation of final controlling equipment
Final controlling equipment must be arranged at the outflow end
spaced at a minimum 5 x DN.

If the medium is conveyed through piston / plunger pumps or
compressors (pressures for fluids > 10 bar (145 psi)), it may be
subject to hydraulic vibration in the pipeline when the valve is closed.
If this does occur, the valve absolutely has to be installed in the flow
direction upstream of the flowmeter. The FS4000 Swirl flowmeter is
particularly suited to such scenarios. Suitable dampers (e.g. air
vessels in the case of pumping using a compressor) might need to be
used.
