14.1 Removal and installation under process pressure
In some cases it might be necessary to remove and reinstall the PIT sensor head for cleaning when
the pipe is under process pressure. A special retraction device can be used for this purpose.
When using this device, it is important to ensure that the sensor head will not be damaged by closing
the valve. For a detailed description of this process, see the Additional Operating Instructions (PIT-
Druck_BA_03_eng) for removal and installation the meter under process pressure (Section 5.1.2).
