5.1.4 Installation for external pressure and temperature
measurement

points

As an option, the flowmeter can be fitted with a Pt100 for
direct temperature measurement. This temperature
measurement enables, for example, the monitoring of the
measuring medium 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 flow computer unit), the measuring points must
be installed as illustrated.
5.1.5 Installation of final controlling equipment
Fig. 12: Installation of final controlling equipment
Final controlling equipment must be arranged at the outflow
end spaced at a minimum 5 x DN. If the measuring medium is
conveyed through piston pumps / plunger pumps or
compressors (pressures for fluids > 10 bar [145 psi]), it may
be subject to hydraulic vibration in the piping when the valve is
closed. If this does occur, it is essential that the valve be
installed in the flow direction upstream of the flowmeter. The
SwirlMaster FSS400 is particularly well suited for such
arrangements. Suitable damping devices (such as air vessels if
using a compressor for conveying) may need to be used.
5.1.6 Sensor insulation

1 Insulation
The piping can be insulated up to a thickness of 100 mm
(4 inch).
5.1.7 Use of trace heating
Trace heating may be used under the following conditions:
— If it is installed directly on or around the piping
— If, in the case of existing pipeline insulation, it is installed
inside the insulation (the maximum thickness of
100 mm [4 inch] must not be exceeded)
— If the maximum temperature the trace heating is able to
produce is less than or equal to the maximum medium
temperature.
NOTE
The installation requirements set out in EN 60079-14 must be
observed.
Please note that the use of trace heaters will not impair EMC
protection or generate additional vibrations.
