The level sensor systems, depending on the design thereof, will be
mounted into the container by means of a flange or a screw-in thread.
Make sure, prior to assembly, that the assembly port provided on
the container and the attachment means of the level sensor system
conform in size and dimension. Depending on the design of the level
sensor system, assembly thereof into the container must be externally.
Assembly must be in the vertical position. To insure a safe function,
the angle of assembly is allowed to differ from the vertical by 30° max.
The guide tube of the level sensor is to be externally introduced through
the assembly port of the container. Attachment thereof is by tightening
the screw-in thread in respect of threaded plugs; by bolting the cap nut
in respect of dairy pipe fittings; screwing in respect of flange-model
designs or closing of the locking rings (articulated clamp) in triclamp-
model clamp connections.
■ Level sensors having screw-in threads are to be screwed
across the entire thread length.
■ Level sensor systems having dairy pipe fittings are
furnished, ex factory, with suitable cap nuts.
■ Level sensor systems of flange-model design are to be
fixed by suitable screws, washers and nuts.
■ Level sensor systems having clamp connections of the
triclamp model are to be secured by means of suitable
locking rings (articulated clamp).
Please observe the torque value of the screws!
4. Assembly
Suitable sealants should be used. Please make sure that the sealing
material is resistant to the fluid and its vapours and to the anticipated
temperatures and pressures.
In designs having floats mounted thereon the diameters of which
exceed the core diameter of the mounting port the floats should be
removed from the guide tube prior to assembly thereof.
