Avoid cross talk
If operating more than one flowmeter in one or multiple interconnected pipelines there is a risk of cross talk.
Prevent cross talk in one of the following ways:
● Mount sensors on separate frames
● Decouple the pipeline using flexible tube or couplings
Figure 4-3 High risk of cross talk when using non-flexible pipes
Figure 4-4 Low risk of cross talk when using flexible pipes and separate frames
Installing the sensor cable
Wiring sensor and transmitter (M12)
The sensor is provided with a preformed cable terminated with M12 style stainless steel weather-proof plugs.
The cable screen is physically and electrically terminated within the body of the plug.
Take care when handling the cable and passing it through cable ducting that the plug is not subjected to excessive tension
(pulling) as the internal connections may be disengaged.
Note
Never pull the cable by the plug - only by the cable itself.
1. Connect sensor using the supplied 4-wire cable with M12 connectors.
Note
Grounding
The sensor cable screen is mechanically connected to the grounding terminal (PE), only when the M12 plug is correctly
tightened.

A: Preparing cable
Prepare the cable by stripping it at both ends.
