Mounting
In case of internal mounting, the instrument has no
displacerchamber;themechanismchamberflangeis
bolted directly on the vessel flange.
In case of liquid turbulence, it is recommended that
the displacer is isolated with a damping chamber to
prevent oscillations.
In case of external mounting, the instrument is connected to the vessel either with flanges or with screwed or welded connections. The
instrument is constructed so that the mid-range level reference on the displacer chamber coincides with the normal level in the vessel.
It is recommended that shut-off valves be inserted between the level connections and the vessel, with a drain valve on the lower part
of the level.
