WARNING
• Installation shall only be performed by qualified personnel and in accordance with local
governing regulations.
• Handle the device using the enclosure, not the process connection tag, to avoid
damage.
• Take special care when handling the threaded PVDF and Flanged encapsulated
antennas. Any damage to the antenna surface, particularly to the tip/lens, could affect
performance.
• Materials of construction are chosen based on their chemical compatibility (or inertness)
for general purposes. For exposure to specific environments, check with chemical
compatibility charts before installing.
Note
•
For European Union and member countries, installation must be according to ETSI EN
302372.
•

Pressure applications
WARNING
Pressure applications
• Never attempt to loosen, remove, or disassemble process connection or device housing
while vessel contents are under pressure.
• The user is responsible for the selection of bolting and gasket (except for Flanged
encapsulated antenna) materials which will fall within the limits of the process
connection and its intended use and which are suitable for the service conditions.
• For Flanged encapsulated antenna, lens acts as integral gasket, no other required
• Use spring washers for Flanged encapsulated antenna.
• Improper installation may result in loss of process pressure.
Note
•
The process connection tag shall remain with the process pressure boundary assembly.
(The process pressure boundary assembly comprises the components that act as a
barrier against pressure loss from the process vessel: that is, the combination of process
connection body and emitter, but normally excluding the electrical enclosure).
•
SITRANS LR250 units are hydrostatically tested, meeting or exceeding the requirements
of the ASME Boiler and Pressure Vessel Code and the European Pressure Equipment
Directive.
4.1.1
Pressure Equipment Directive, PED, 97/23/EC
Siemens Level Transmitters with flanged, threaded, or sanitary clamp type process mounts have
no pressure-bearing housing of their own and, therefore, do not come under the Pressure
Equipment Directive as pressure or safety accessories (see EU Commission Guideline 1/8 and
1/20).

Beam angle
Note
•
Beam width depends on antenna size: see below.
•
For details on avoiding false echoes, see Auto False Echo Suppression (Page 221).
● Beam angle is the width of the cone where the energy density is half of the peak energy
density.
● The peak energy density is directly in front of and in line with the antenna.
● There is a signal transmitted outside the beam angle, therefore false targets may be
detected.

Mounting on a Stillpipe or Bypass Pipe
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 182) 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 or Raised-Face Flange per
EN 1092-1 (Page 208).
● One continuous length of metallic pipe is preferred, without joints. Bad joints create
reflections.
● Joints (if unavoidable) must be machined to ± 0.25 mm (± 0.010") and must have welded
connecting sleeve on the outside.
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")
Not recommended:

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 221)
for a
more detailed explanation.

Password protection
An AMS Device Manager administrator can configure the user to require a password. The use of
passwords is recommended. A password should be assigned to the ’admin’ username
immediately after installing AMS Device Manager.
Each user is given an AMS Device Manager username and password and required to enter
them when they start AMS Device Manager. Access to functions depends on the level of
permissions granted.
Login types
● standard, local, or domain
A standard user can change their password in AMS Device Manager. A Local or Domain
Windows user cannot change their password using AMS Device Manager and must request
their network administrator to do so.

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 61) 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
.
