    • Ensure that the permitted maximum operating pressure and temperatures for the device are not being exceeded. (See point 13 Technical Information) Installation: Mount the sensor in the pipe (KAL-1...)- in a sleeve welded to the pipe (KAL-2...). Fitting position: The function of the sensor is not dependent on their fitting position, provided that the pipe is completely filled with flow medium.
