The LFS range of flow switches are paddle
devices that are mounted vertically
through a socket or upstand process
connection.
Electrical connections are made within the
housing, which has a screw on sealed lid
and cable gland.
A choice of paddle sizes is supplied with
each switch and selection can be made
