INFORMATION!
The maximum permissible product temperatures listed in the tables are valid under
the following conditions:
•
The measuring device is installed and operated in accordance with the manufacturer's
installation instructions.
•
It must be ensured that the flowmeter is not heated by the effects of additional heat radiation
(sunshine, neighbouring system components) and thus operated above the permissible
ambient temperature range.
•
Insulation must be limited to the piping. Unobstructed ventilation of the signal converter
must be ensured.
