3.5.5 Pipes with cathodic protection
Pipes with electric corrosion protection are generally insulated inside and outside so that the
fluid has no conductive connection to the ground. The flow meter must be insulated from the
pipe. Observe the following instructions when installing the flow meter:
• The pipe flanges must be connected to each other using a copper cable (L), but must not be
connected to the flowmeter.
• The bolts for the flange connections and the gaskets must be insulated. Use sleeves and
washers that are made of insulating material (these must be provided by customer).
