The level switch has a threaded, flanged, or Tri Clamp process connection for
mounting it onto a silo (or other vessel). You can mount it on a side wall of
the silo, so that it is level with the filling limit to be monitored. Alternatively,
if it has an extended length, mount it vertically on top of a silo to monitor the
maximum filling limit.
The length of the fork can be up to 157.5 in. (4 m) with an extension tube or
up to 787 in. (20 m) with an extension cable.
The use of a sliding sleeve is recommended so that the switching point can
be changed easily during the live operation of the level switch.
