2. Design and function
2.1 Description
The models FLM-CA and FLM-CM high-accuracy level transmitters are used for the
continuous measurement of the level of liquid media in vessels. The measurement
procedure used exploits the physical effect of magnetostriction and is largely independent
of the temperature. It is used, especially, where very precise level measurements are
required, such as in the chemical industry.
In these operating instructions, the FLM is described with cable connection on the side of
the probe head. As cable connection, an M12 cable gland (also with M16 adapter), an M12
connector or an M20 or ½ NPT female thread are possible. As a further variant, there is an
FLM with an M12 connector on the probe head cover.
