If EL 4 is mounted in the filling stream, unwanted false measurement
signals can be generated. For this reason, mount EL 4 at a position in
the vessel where no disturbances, e.g. from filling openings, agitators,
etc., can occur.
This applies particularly to instrument versions with a longer probe.

The probe should protrude into the vessel to avoid buildup. For that
reason, avoid using high mounting bosses for screw-in fittings. This
applies particularly to use in adhesive products.
Make sure that the mechanical connection of the probe to the vessel
is electrically conductive to ensure sufficient grounding.
Use conductive seals, such as those made of copper or lead, etc.
Insulating measures, such as covering the thread with Teflon tape,
can interrupt the necessary electrical connection with metal vessels.
For this reason, ground the probe on the vessel or use a conductive
seal material.
