Environment
Ambient temperature range Transmitter
• Standard: –20 to +60 °C (–4 to +140 °F)
• Optional: –40 to +60 °C (–40 to +140 °F)
!
Note!
At ambient temperatures below –20 °C (–4 °F) the readability of the display may be impaired.
Sensor
• –40 to +60 °C (–40 to +140 °F)
!
Note!
The permitted temperature range of the measuring tube lining may not be undershot or overshot (
20, Section "Medium temperature range").
Please note the following points:
• Install the device at a shady location. Avoid direct sunlight, particularly in warm climatic regions.
• The transmitter must be mounted separate from the sensor if both the ambient and fluid
temperatures are high.
Storage temperature The storage temperature corresponds to the operating temperature range of the measuring
transmitter and the appropriate measuring sensors.
!
Note!
• The measuring device must be protected against direct sunlight during storage in order to avoid
unacceptably high surface temperatures.
• A storage location must be selected where moisture does not collect in the measuring device. This
will help prevent fungus and bacteria infestation which can damage the liner.
• If protecting caps or protective covers are mounted, these must not be removed before mounting the
device.
Degree of protection • Standard: IP 67 (NEMA 4X) for transmitter and sensor.

Process
Medium temperature range The permissible medium temperature depends on the sensor and the sealing material:
Sensor:
• DN 2 to 150 (¹⁄ to 6"): –20 to +150 °C (–4 to +302 °F)
Seals:
• EPDM: –20 to +150 °C (–4 to 302 °F)
• Viton (FKM): –20 to +150 °C (–4 to 302 °F)
• Silicone (VMQ): –20 to +150 °C (–4 to 302 °F)
• Kalrez: –20 to +150 °C (–4 to 302 °F)
