Thermal insulation
For optimum temperature measurement and mass calculation, heat transfer at the
sensor must be avoided for some fluids. This can be ensured by installing thermal
insulation. A wide range of materials can be used to provide the required thermal
insulation.
This applies for:
•
Compact version
• Remote sensor version
The maximum insulation height permitted is illustrated in the diagram:
1
A0019212
1 Maximum insulation height
‣
When insulating, ensure that a sufficiently large area of the housing support
remains exposed.
The uncovered part serves as a radiator and protects the electronics from overheating
and excessive cooling.
NOTICE
Electronics overheating on account of thermal insulation!
‣
Observe the maximum permitted insulation height of the transmitter neck so that
the transmitter head and/or the connection housing of the remote version is
completely free.
‣
Observe information on the permissible temperature ranges.
‣
Note that a certain orientation might be required, depending on the fluid
temperature
(→  12).
For detailed information about the fluid temperature, orientations and permitted
temperature ranges, refer to the Operating Instructions for the device on the CD-
ROM provided
Vibrations
The correct operation of the measuring system is not affected by plant vibrations up to
1 g
, 10 to 500 Hz. Therefore no special measures are needed to secure the sensors.
