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 DC of the upper medium must be known and constant. The DC can be determined with the
aid of the "DC manual" CP00019F/00/EN. In addition, it is also possible to calculate the DC
automatically in FieldCare if the interface thickness is available and known.
• The DC of the upper medium may not be greater than 10.
• The DC 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.

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.
• If a rod probe is used, the probe length must
be 100 mm longer than the lower disposal.
• 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 (→ä58, "Centering
disks").

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".
• A 4 mm Allen key for turning the housing.
3.6.2 Shortening probes
!Note!
When shortening the probe: Enter the new length of probe into the Quick Setup which can be found
in the electronics housing under the display module.
L00-FMP4xxxx-16-00-00-xx-004
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 G1½" adapter
Sealing form at the FMP45 corresponds the DIN 3852 Part1, screwed end form A. The screwed end
has an overall length of 45 mm. In addition, suitable sealing ring as per DIN 7603 with dimensions
48x55 mm. 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.

3.6.4 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 ("Ordering structure", s. Seite 6).
• 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 ("Accessories", →ä58).

3.6.5 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.

3.6.6 Notes on special mounting situations
Welding the probe into the vessel
"Caution!
Before welding the probe into the vessel, it must be grounded by a low-resistive connection. If this
is not possible, the electronics as well as the HF module must be removed. Otherwise the electronics
may be damaged.
Installation at an angle
• For mechanical reasons, rod probes should be
installed as vertically as possible.
• If installing at an angle, the probe length must
be limited, depending on the angle of
installation.
– Up to 1 m = 30°
– Up to 2 m = 10°
– Up to 4 m = 5°
L00-FMP4xIxx-17-00-00-en-048
Separable probes
If there is little mounting space (distance to the
ceiling), it is advisable to use separable rod pro-
bes (∅16 mm).
• max. probe length 10 m (394 in)
• max. sideways capacity 20 Nm
• probes are separable several times with the
lengths:
– 500 mm (19.68 in)
