• 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.
Storage temperature 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).
