2. Design and function
The FLM-Cx emits a 4 ... 20 mA output signal, which is configured via buttons within the
probe head, or a digital output signal as HART
Probe lengths of 100 mm to 6 m, as "Flex version" up to 10 m, and also various
temperature and pressure ranges are possible.
Available versions:
With screw-in body, welded or for step-free positioning
■
With flange process connection
■
For mounting on a bypass with magnetic float
■
With 90° angled probe head
■
With 6 mm guide tube
■
With 6 mm guide tube and short cable bushing

2.2 Construction and principle of operation
The construction of the model FLM-Cx level transmitter is illustrated in the version with
screw-in body. In the probe head  of the level transmitter are located the connection
terminals and the adjustment buttons protected by the cover . The electrical connection
is made via an M16 x 1.5 cable gland  or M12 plug connection on the top of the probe
head and the ground connection  at the bottom of the probe head (see chapter 5.1
"Mounting" and 5.3 "Adjustment").
On the guide tube , for highly-adjustable mounting in the vessel, there is a screw-in
body  (compression fitting) or, for fixed mounting, a flange (not shown). The float  is
used for the continuous measurement of the product filling height or interface layer and is
held on the guide tube by an adjusting collar .
The "BLM for bypass fitting" version is delivered without process connection and float.
