Installation
Carefully clean the connections before at-
taching the differential pressure lines. Do not
rinse the device with compressed air or pres-
surized water.
Mount the device to a pipe, wall or mounting
plate free of vibration.
Use mounting part with clamp for pipe
mounting to attach it to a vertical or horizon-
tal pipe. Use a mounting part without clamp
for wall mounting. A bracket is required for
for panel mounting (see section 12 on
page 37).
4.3 Differential pressure lines
Install the differential pressure lines (pipes
with 12 mm outside diameter) as shown in
Fig. 3. Make sure you observe the proper or-
der. Use appropriate screw fittings to ensure
that the lines do not leak.
Install line sections, which would usually run
horizontally, with a constant downward
slope of at least 1:20, starting the slope ei-
ther at the orifice plate or at the point where
venting is possible. The smallest permissible
bending radius is 50 mm. Thoroughly flush
the differential pressure lines before connect-
ing them to the device. Make sure that the
high-pressure line is connected to the
high-pressure connection and the low-pres-
sure line is to the low-pressure connection.
4.4 Orifice flange (orifice plate
assembly)
The direction of flow must correspond to the
arrow on the orifice plate. Unobstructed pipe
sections are required upstream and down-
stream of the orifice plate assembly. For the
orifice tubes delivered by SAMSON, these
section are ensured by the weld-on calibra-
tion pipes. For orifice flanges, the unobstruct-
ed pipe section upstream of the orifice plate
is specified in the order confirmation. Make
sure the orifice plate assembly as well as the
gaskets are properly aligned with the pipe-
line.
