Potential equalization
Perfect measurement can only be guaranteed if the fluid and sensor are on the same electric potential. This is
ensured by the two ground disks of the sensor.
The following should also be taken into consideration for potential equalization:
• Internal grounding concepts in the company
• Operating conditions, such as the material/grounding of the pipes, cathodic protection etc. (see table)

Operating conditions
Potential equalization
When using the measuring device in a:
• Metal, grounded pipe
• Plastic pipe
• Pipe with insulating lining
Potential equalization takes place via the ground terminal of the
transmitter (standard situation).
!
Note!
When installing in metal pipes, we recommend you connect the
ground terminal of the transmitter housing with the piping.
