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 ambient temperature range of the
measuring transmitter and the appropriate measuring sensors and the corresponding
sensor cable (see above).
