Immersion depth of PITe-*** in the pipe
The weld spigots must be installed so that the sensor head projects 40 mm into the pipeline,
regardless of the pipes nominal diameter.
Caution:
Before welding the socket to the pipe, it is essential that the sensor be removed from the
welding socket!

7.1.3
Earthing – potential equalisation
The sound grounding concept of the flowmeter is a necessity for both safety reasons as well as to ensure
a faultless operation. In accordance with VDE 0100 Part 410 and VDE 0100 Part 540 the grounding
connections must be at protective conductor potential.
For metrological reasons, this potential must
be identical to the potential of the fluid
. The grounding cable should not transmit any interference
voltage. For this reason do not simultaneously ground other electrical devices with this cable.
