–20...+80 °C
• Flowrate measuring sensors Prosonic Flow U (Clamp On):
–20...+60 °C
• Flowrate measuring sensors Prosonic Flow W (Insertion)
–40...+80 °C
• Sound velocity measuring sensors DDU 18:
–40...+80 °C / 0...+170 °C
• Wall thickness measuring sensor DDU 19:
0...+60 °C
• Sensor cable PTFE: –40...+170 °C;

• In heated piping or piping conveying cold fluids, it is always permissible to insulate
the piping completely with the mounted ultrasonic sensors.
• Install the transmitter at a shady location. Avoid direct sunlight, particularly in warm
climatic regions.
The storage temperature corresponds to the operating temperature range of the meas-
uring transmitter and the appropriate measuring sensors and the corresponding sensor
cable (see above).
