ISPLACERS
Since the displacer is not hanging inside a chamber (as on the contrary LL, LF, TF, TL), special
arrangements are to be provided if the liquid is turbulent.
For top flange mounted Transmitters (type SI), a stilling well may be installed coaxially with the
displacer, and fixed either to vessel or to Transmitter flanged connection. The well is made
from tubing or pipe with an inside diameter 50/80 large than the diameter of the displacer, the
well should be mounted so that it extends at least 100 mm below the displacer when the
displacer is hanging free and should have a number of drilled holes in the side to allow free
circulation of the liquid.
For side flange mounted Transmitters (type LI), a bracket may be mounted inside the tank or
vessel, with a suitable diameter hole to allow the clearances noted above, located 50 mm about
above the lower end of the displacer and coaxially with the displacer when the displacer is
hanging free.
