maximum 180 °C (356 °F).
Not thermally insulated: The flowmeter sensor is not surrounded by pipe insulation material.
Thermally insulated: The flowmeter sensor is surrounded by pipe insulation material.
Note
The standard version includes explosion protection for gases and dust. Explosion protection for dust is only available for devices featuring a
transmitter in a dual-compartment housing.
• If the installation location for the device is classified as a potentially explosive area for gases and dust, the temperature data in the "Gas &
dust" columns in the table must be taken into consideration.
• If the installation location for the device is classified as a potentially explosive area for gases only, the temperature data in the "Gas" column
in the table must be taken into consideration.
