!
Note!
At ambient temperatures below –20°C the readability of the display may be impaired.
• Flowrate measuring sensors Prosonic Flow P (clamp-on):
–40...+80 °C / 0...+170 °C
• Flowrate measuring sensors Prosonic Flow W (clamp-on):
–20...+80 °C
• Flowrate measuring sensors Prosonic Flow U (clamp-on):
–20...+60 °C
• Flowrate measuring sensors Prosonic Flow W (Insertion):
–40...+80 °C
• Sensor cable PTFE: –40...+170 °C; Sensor cable PVC: –20...+70 °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 measuring transmit-
ter and the appropriate measuring sensors and the corresponding sensor cable (see above).
