Conduit entries and connections
Transmitter conduit entries ports are ½"-14NPT as standard, M20 conduit
connections will use an adapter. Conduit connections should be made in
accordance with national, local, and plant electrical codes. Unused conduit
entries should be sealed with the appropriate certified plugs. The plastic
shipping plugs do not provide ingress protection.

Conduit requirements
•
For installations with an intrinsically safe electrode circuit, a separate
conduit for the coil cable and the electrode cable may be required.
•
For installations with non-intrinsically safe electrode circuit, a single
dedicated conduit run for the coil drive and electrode cable between the
sensor and the remote transmitter may be acceptable. Removal of the
barriers for intrinsic safety isolation is permitted for non-intrinsically safe
electrode installations.
•
Bundled cables from other equipment in a single conduit are likely to
create interference and noise in the system. See
•
Electrode cables should not be run together in the same cable tray with
power cables.
•
Output cables should not be run together with power cables.
•
Select conduit size appropriate to feed cables through to the flowmeter.
