A stillpipe or bypass pipe is used for products with a low dK, or when vortex or extremely
turbulent conditions exist. It can also be used to provide optimum signal conditions on foaming
materials. See Dielectric constant of material measured in Performance (Page 199) for more
information.
● The pipe diameter must be matched with the antenna size. Use the largest antenna size that
will fit the stillpipe/bypass pipe1). See Threaded Horn dimensions, Raised-Face Flange per
EN 1092-1 (Page 243), Flanged encapsulated dimensions (Page 218)or Hygienic
encapsulated dimensions (Page 222).
● One continuous length of metallic pipe is preferred, without joints.
● Any false reflections created by joints/welds/imperfections will lead to inaccuracies of the
measurement.
● Joints (if unavoidable) must be machined to ± 0.25 mm (± 0.010") and must have welded
connecting sleeve on the outside.
● If using any hygienic process connections in conjunction with a stillpipe/bypass, please
ensure that the antenna/lens are cleanable in accordance with the applicable approval.
1) Mounting in a pipe greater than 100 mm (4") can cause large errors, and therefore is not
recommended.
Suitable pipe diameters:
Horn antenna
40 to 100 mm (1.5 to 4")
PVDF antenna
50 mm (2") only
Flanged encapsulated antenna
50 to 100 mm (2 to 4")

Auto false echo suppression
Note
•
Ensure material level is below all known obstructions when using Auto False Echo
Suppression to learn the echo profile. An empty or almost empty vessel is recommended.
•
Note the distance to material level when learning the echo profile, and set Auto False
Echo Suppression Range to a shorter distance to avoid the material echo being screened
out.
•
Set Auto False Echo Suppression and Auto False Echo Suppression Range during
startup, if possible.
•
If the vessel contains an agitator it should be running.
•
Before adjusting these parameters, rotate the device for best signal (lower false-echo
amplitude).
If you have a vessel with known obstructions, use Auto False Echo Suppression to prevent false
echo detection. This feature can also be used if the device displays a false high level, or the
reading is fluctuating between the correct level and a false high level.
The device learns the echo profile over the whole measurement range and the TVT is shaped
around all echoes present at that moment. See Auto False Echo Suppression (Page 259)
for a
more detailed explanation.

Operating via FDT (Field Device Tool)
FDT is a standard used in several software packages designed to commission and maintain field
devices. Two commercially available FDTs are PACTware and Fieldcare.
Functionally FDT is very similar to PDM. See Operating via SIMATIC PDM (Page 77) for more
detail.
● To configure a field device via FDT you need the DTM (Device Type Manager) for the device.
● To configure a field device via SIMATIC PDM, you need the EDD (Electronic Data
Description) for the device.
7.3.1
Device Type Manager (DTM)
A DTM is a type of software that ’plugs into’ FDT. It contains the same information as an EDD
but an EDD is independent of the operating system.
7.3.2
SITRANS DTM
● SITRANS DTM is an EDDL interpreter developed by Siemens to interpret the EDD for that
device.
● To use SITRANS DTM to connect to a device, you must first install SITRANS DTM on your
system and then install the device EDD written for SITRANS DTM.
● You can download SITRANS DTM from the Siemens service and support website. Go to
Service & Support (http://www.siemens.com/automation/service&support), click on
Product
Support
, and drill down to
Product Information/Automation Technology/Sensor
systems/Process Instrumentation/Software & Communications

Auto False Echo Suppression (2.8.7.1.)
Used together with
Auto False Echo Suppression Range (2.8.7.2.)
to screen out false echoes in
a vessel with known obstructions. A ’learned TVT’ (time varying threshold) replaces the default

Auto False Echo Suppression (Page 259)
for a more detailed
explanation.
Note
•
Make sure material level is below all known obstructions when Auto False Echo
Suppression is used to learn the echo profile. (An empty or almost empty vessel is
recommended.)
•
Note the distance to material level when Auto False Echo learns the environment. Set
Auto False Echo Suppression Range to a shorter distance to avoid the material echo
being screened out.
•
Set Auto False Echo Suppression and Auto False Echo Suppression Range during
startup, if possible.
