Caution.
For safety reasons and optimum performance, the flowmeter, pipelines and medium must be
correctly bonded and grounded according to regulations.
Note.
Connect the transmitter ground connection to the flowmeter body ground
– see Fig. 3.3 and Fig. 3.4.
The flow sensor must not be connected to a ground spike.

Older sensors from DN40 to DN80, that are fitted with bare metal stainless steel flanges, do not
require fluid contact rings.
