PROline Promass 80 3 Installation

• Information on permissible temperature ranges → Page 88.
Special heating jackets which can be ordered as accessories from Endress+Hauser are
available for the sensors.
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.
Fig. 8: 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 (see Fig. 8).
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
See the information on Page 81 and 89.
