3.4 General information on interface measurement
The Levelflex M with the "interface" electronics version is the ideal solution for measuring
interfaces. The device measures variable interfaces and variable total levels simultaneously.
L00-FMP4xIxx-15-00-00-en-001
In addition, the following general conditions must be observed for interface measurement:
• The DK of the upper medium must be known and constant. The DK can be determined with the
aid of the DK manual SD106F. In addition, it is also possible to calculate the DK automatically in
FieldCare if the interface thickness is available and known. →ä59
• The DK of the upper medium may not be greater than 10.
• The DK difference between the upper medium and lower medium must be >10.
• The interface must have a minimum thickness of 60 mm.
• Emulsion layers in the vicinity of the interface can severely dampen the signal. However,
emulsion layers up to 50 mm are permitted.
• The measuring range for interface measurement is limited to 10 m. Larger measuring range
available on request.

3.4.1 Electronics
The process variables are output using the dynamic variables of the HART protocol. The process
variables can be flexibly assigned to the dynamic variables (primary, secondary, tertiary, quaternary
value).
3.4.2 Using the HART loop converter HMX50:
The dynamic variables of the HART protocol can be converted into individual 4 to 20 mA sections
using the HART loop converter HMX50. The variables are assigned to the current output and the
measuring ranges to the individual parameters in the HMX50.
L00-FMP40xIx-04-00-00-en-004
Fig. 2: Connection diagram for HART loop converter HMX50 (example: passive 2-wire device and current outputs
connected as power source)
The HART loop converter HMX50 can be acquired using the order number 71063562.

3.5 Special information on interface measurement
Installation in horizontal cylindrical, upright and underground tanks
• Use coax probes or rod probes in the bypass/stilling well. A segmented probe is available as a
special version for longer measuring ranges.
• Any distance from the wall is possible for coax probes or rod probes in the stilling well. In the case
of rod probes, it must be ensured that the probe does not come into contact with the wall.
L00-FMP4xIxx-17-00-00-xx-002
!Note!
Rope and rod probes can only be freely installed in the tank under certain circumstances - please
contact your Endress+Hauser office.
Installation in stilling well or bypass
• A rod probe can be used for pipe diameters
bigger than 40 mm.
• Rod probe installation can take place up to a
diameter size of 100 mm. In the event of
larger diameters, a coax probe is
recommended.
• Welded joints that protrude up to approx.
5 mm inwards do not affect the measurement.
• The pipe may not exhibit any steps in
diameter.
• In the case of rod probes, it must be ensured
that the probe does not come into contact
with the wall. If necessary, use a centering
disk at the end of the probe.
!Note!
A plastic centering disk has to be used for
interface measurement (see Accessories
→ä57).

3.6 Installation instructions
3.6.1 Mounting kit
In addition to the tool needed for flange mounting, you will require the following tool:
• For mounting adapters: 60 mm open-end spanner for 1½", 50 mm open-end spanner for ¾".
• A 4 mm Allen key for turning the housing.
3.6.2 Shortening probes
Rod probes
It is necessary to shorten a rod probe if the distance to the tank floor or outlet cone is less than
50 mm. The rods of a rod probe are shortened by sawing or separating at the bottom end.
Coax probes
It is necessary to shorten a coax probe if the distance to the tank floor or outlet cone is less than
10 mm.
Coax probes can be shortened a maximum of 80 mm from the end. They have centering units inside
which fix the rod centrally in the pipe. The centerings are held on the rod by flanges. Shortening is
possible up to approx. 10 mm below the centering.
!Note!
Seal for devices with G 1½" adapter
The thread and type of seal on FMP45 corresponds to DIN 3852 Part 1, screwed plug form A.
Sealing rings as per DIN 7603 with dimensions 48x55 mm can be used for this.
Please use a sealing ring according to this standard in the form A, C or D and of a material that is
resistant to the application.
Supporting probes against warping
For Ex approval:
A support is required for probe lengths ≥3 m, (see drawing).

3.6.3 Replacing a displacement system in an existing displacer
chamber
The Levelflex M is a perfect replacement for a conventional displacer system in an existing displacer
chamber. In addition to the DIN and ANSI flanges, which are available as standard,
Endress+Hauser also offers flanges that suit Fischer and Masoneilan displacer chamber (special
product) for this purpose. Thanks to menu-guided local operation, commissioning the Levelflex M
only takes a few minutes. Replacement is also possible when partially filled, and wet calibration is
not required.
Your benefits:
• No moving parts, thus zero-maintenance operation.
• Not sensitive to process influences such as temperature, density, turbulence and vibrations.
• The rod probes can be shortened or replaced easily. In this way, the probe can be easily adjusted
on site.
L00-FMP4xIxx-17-00-00-en-002
Planning instructions:
• In normal cases, use a rod probe. When installing into a metal displacement housing up to
150 mm (100 mm for interface), you have all the advantages of a coax probe.
• It must be ensured that the probe does not come into contact with the side wall. Where necessary,
use a centering disk at the lower end of the probe (special product).
• A centering disk must be adapted as accurately as possible to the internal diameter of the displacer
chamber to also ensure perfect operation in the area of the probe end.
Additional information on interface measurement
• The pipe may not exhibit any steps in diameter. Use the coax probe where necessary.
• In the case of rod probes, it must be ensured that the probe does not come into contact with the
wall. If necessary, use a centering disk at the end of the probe.
!Note!
A plastic centering disk has to be used for interface measurement, see Accessories →ä57.

3.6.4 Installing with heat insulation
• If process temperatures are high (≥200 °C), FMP45 must be included in normal tank insulation
to prevent the electronics heating up as a result of thermal radiation or convection.
• The insulation may not go beyond the points labeled "MAX" in the drawings.
