3.2.5 Thermal insulation
Some fluids require suitable measures to avoid loss of heat at the sensor. A wide range of materials
can be used to provide the required thermal insulation.
F06-83FHTxxx-06-00-xx-xx-001
Fig. 10: In the case of the Promass F high-temperature version, a maximum insulation thickness of 60 mm must be
observed in the area of the electronics/neck.
If the Promass F high-temperature version is installed horizontally (with transmitter head pointing
upwards), an insulation thickness of min. 10 mm is recommended to reduce convection. The
maximum insulation thickness of 60 mm must be observed.
3.2.6 Inlet and outlet runs
There are no installation requirements regarding inlet and outlet runs. If possible, install the sensor
well clear of fittings such as valves, T-pieces, elbows, etc.
3.2.7 Vibrations
The high oscillation frequency of the measuring tubes ensures that the correct operation of the
measuring system is not influenced by pipe vibrations. Consequently, the sensors require no special
measures for attachment.
3.2.8 Limiting flow
