6.1.4 Measurement in a plastic vessel

If the outer wall of the vessel is made of a non-conductive material (e.g. GRP), microwaves
can also be reflected off interfering installations outside the vessel (e.g. metallic pipes (1),
ladders (2), grates (3), ...). Therefore, there should be no such interfering installations in
the signal beam. Please contact Endress+Hauser for further information.

6.1.5 Optimization options

• Antenna size
The bigger the antenna, the smaller the beam angle α and the fewer interference echoes
→  22.
• Mapping
The measurement can be optimized by means of electronic suppression of interference
echoes.
See the Confirm distance parameter (→  111) for details.
• Antenna alignment

5 Relationship between beam angle α, distance D and beamwidth diameter W

The beam angle is defined as the angle α where the energy density of the radar waves
reaches half the value of the maximum energy density (3-dB-width). Microwaves are also
emitted outside the signal beam and can be reflected off interfering installations.

6.2 Measuring conditions

• In case of boiling surfaces, bubbling or tendency for foaming use FMR53 or FMR54.
Depending on its consistence, foam can either absorb microwaves or reflect them off the
foam surface. Measurement is possible under certain conditions. For FMR50, FMR51
and FMR52, the additional option "Advanced dynamics" is recommended in these cases
(feature 540: "Application Package", option EM).
• In case of heavy steam development or condensate, the maximum measuring range of
FMR50, FMR51 and FMR52 may decrease depending on density, temperature and
composition of the steam → use FMR53 or FMR54.
• For the measurement of absorbing gases such as ammonia NH3 or some
fluorocarbons 2), please use Levelflex or Micropilot FMR54 in a stilling well.
• The measuring range begins, where the beam hits the tank bottom. Particularly with
dish bottoms or conical outlets the level cannot be detected below this point.
• In stilling well applications, the electromagnetic waves do not propagate completely
outside the tube. It must be taken into account that the accuracy may be reduced in the
area C. In order to guarantee the required accuracy in these cases, it is recommended to
position the zero-point at a distance C above the end of the tube (see figure).
• In case of media with a low dielectric constant (εr = 1.5 to 4) 3) the tank bottom can be
visible through the medium at low levels (low height C). Reduced accuracy has to be
expected in this range. If this is not acceptable, we recommend positioning the zero
point at a distance C (see figure) above the tank bottom in these applications.
• In principle it is possible to measure up to the tip of the antenna with FMR51, FMR53
and FMR54. However, due to considerations regarding corrosion and build-up, the end
of the measuring range should not be chosen any closer than A (see figure) to the tip of
the antenna.
• When using FMR54 with planar antenna, especially for media with low dielectric
constants, the end of the measuring range should not be closer than A: 1 m (3.28 ft) to
the flange.
• The smallest possible measuring range B depends on the antenna version (see figure).
• The tank height should be at least H (see table).

2) Affected compounds are e.g. R134a, R227, Dymel 152a.

3) Dielectric constants of important media commonly used in various industries are summarized in the DC manual (CP01076F) and in the Endress
+Hauser "DC Values App" (available for Android and iOS).

6.3 Mounting cladded flanges

• Use flange screws according to the number of flange holes.
• Tighten the screws with the required torque (see table).
• Retighten the screws after 24 hours or after the first temperature cycle.
• Depending on process pressure and process temperature check and retighten the
screws at regular intervals.
Usually, the PTFE flange cladding also serves as a seal between the nozzle and the
device flange.

Alignment
• Align the antenna vertically to the product surface.
The maximum range may be reduced if the horn antenna is not vertically aligned.
• A marking at the flange (somewhere between the flange holes) or the boss enables
alignment of the antenna. This marking must be aligned towards the tank wall as well
as possible.

If the antenna doesn't extend below the nozzle, observe the following:
• The nozzle end must be smooth and free of burrs. If possible its edge should be
rounded.
• An interference echo suppression must be performed.
• Please contact Endress+Hauser for applications with higher nozzles than those
indicated in the table.
• For mounting in heigh nozzles the device is available in a version with an antenna
extension of up to 1 000 mm (39.4 in) 4)
• The antenna extension may cause interference echoes in the near range. In this
case it may occur that the maximum measurable level is reduced.

Threaded connection
For devices with a threaded connection it may be necessary - depending on the
antenna size - to unmount the horn before fastening the device and to mount it again
afterwards.
• Tighten with the hexagonal nut only.
• Tool : 55 mm hexagonal wrench
• Maximum permissible torque: 60 Nm (44 lbf ft)

6.4.2 Mesurement from the outside through plastic walls (FMR50/

FMR51)
• Dielectric constant of the medium: εr > 10
• If possible, use an antenna 100 mm (4 in).
• The distance from the lower edge of the antenna to the tank ceiling should be about
100 mm (4 in).
• If possible, avoid mounting locations where condensation or build-up might occur.
• In case of outdoor mounting, the space between antenna and vessel has to be protected
from the elements.
• Do not mount any potential reflectors (e.g. pipes) outside the tank in the signal beam.

8 Installation in stilling well

1 Marking for antenna alignment

• For horn antenna: Align the marking towards the slots of the stilling well.
• Measurements can be performed through an open full bore ball valve without any
problems.
• After mounting, the housing can be turned 350° in order to facilitate access to the
display and the terminal compartment →  33.

6.5.1 Recommendations for the stilling well

• Metal (no enamel coating; plastic on request).
• Constant diameter.
• Diameter of stilling well not larger than antenna diameter.
• Diameter difference between horn antenna and inner diameter of the stilling well as
small as possible.
• Weld seam as smooth as possible and on the same axis as the slots.
• Slots offset 180° (not 90°).
• Slot width or diameter of holes max. 1/10 of pipe diameter, de-burred. Length and
number do not have any influence on the measurement.
• Select horn antenna as big as possible. For intermedaite sizes (e.g. 180 mm (7 in)) select
next larger antenna and adapt it mechanically (for horn antennas)
• At any transition (i.e. when using a ball valve or mending pipe segments), no gap may be
left exceeding 1 mm (0.04 in).
• The stilling well must be smooth on the inside (average roughness Rz ≤
6.3 μm (248 μin)). Use extruded or parallel welded metal pipe. An extension of the pipe
is possible with welded flanges or pipe sleeves. Flange and pipe have to be properly
aligned at the inside.
• Do not weld through the pipe wall. The inside of the stilling well must remain smooth. In
case of unintentional welding through the pipe, the weld seam and any unevenness on
the inside need to be carefully removed and smoothened. Otherwise, strong interference
echoes will be generated and material build-up will be promoted.
• In the case of smaller nominal widths flanges must be welded to the pipe such that they
allow for a correct orientation (marker aligned toward slots).

ground terminal (11).
In order to ensure electromagnetic compatibility (EMC): Do not only ground the device
via the protective earth conductor of the supply cable. Instead, the functional
grounding must also be connected to the process connection (flange or threaded
connection) or to the external ground terminal.
An easily accessible power switch must be installed in the proximity of the device. The
power switch must be marked as a disconnector for the device (IEC/EN61010).

8.2.2 User roles and related access authorization

The two user roles Operator and Maintenance have different write access to the
parameters if a device-specific access code has been defined. This protects the device
configuration via the local display from unauthorized access →  52.

8.2.3 Write protection via access code

Using the device-specific access code, the parameters for the measuring device
configuration are write-protected and their values can no longer be changed via local
operation.

Define access code via local display

1. Navigate to: Setup → Advanced setup → Administration → Define access code
→ Define access code
2. Define a max. 4-digit numeric code as an access code.
3. Repeat the same code in Confirm access code parameter.
 The -symbol appears in front of all write-protected parameters.

Define access code via operating tool (e.g. FieldCare)

1. Navigate to: Setup → Advanced setup → Administration → Define access code
2. Define a max. 4-digit numeric code as an access code.
 Write protection is active.

Parameters that can always be changed

The write protection does not include certain parameters that do not affect the
measurement. Despite the defined access code, they can always be modified, even if the
other parameters are locked.
If no key is pressed for 10 minutes in the navigation and editing mode, the device
automatically locks the write-protected parameters. If the user goes from the navigation
and editing mode back to the measured value display mode, the device automatically locks
the write-protected parameters after 60 s.
• If write access is activated via access code, it can be also be deactivated only via the
access code →  53.
• In the "Description of Device Parameters" documents, each write-protected
parameter is identified with the -symbol.

Micropilot FMR51, FMR52 HART Operation options

8.2.4 Disabling write protection via access code

If the -symbol appears on the local display in front of a parameter, the parameter is
write-protected by a device-specific access code and its value cannot be changed at the
moment using the local display →  52.

The locking of the write access via local operation can be disabled by entering the device-
specific access code.
1. After you press , the input prompt for the access code appears.
2. Enter the access code.

Maintenance Micropilot FMR51, FMR52 HART

13 Maintenance
The measuring device requires no special maintenance.

13.1 Exterior cleaning

When exterior-cleaning the device, always use cleaning agents that do not attack the
surface of the hosuing and the seals.

13.2 Replacing seals

The process seals of the sensors (at the process connection) must be replaced periodically,
particularly if molded seals (aseptic construction) are used. The period between changes
depends on the frequency of cleaning cycles and on the temperature of the measured
substance and the cleaning temperature.

14 Repairs

14.1 General information on repairs

14.1.1 Repair concept

The Endress+Hauser repair concept assumes that the devices have a modular design and
that repairs can be done by the Endress+Hauser service or specially trained customers.
Spare parts are contained in suitable kits. They contain the related replacement
instructions.
For more information on service and spare parts, contact the Service Department at
Endress+Hauser.

14.1.2 Repairs to Ex-approved devices

When carrying out repairs to Ex-approved devices, please note the following:
• Repairs to Ex-approved devices may only be carried out by trained personnel or by the
Endress+Hauser Service.
• Comply with the prevailing standards, national Ex-area regulations, safety instructions
(XA) and certificates.
• Only use original spare parts from Endress+Hauser.
• When ordering a spare part, please note the device designation on the nameplate. Only
replace parts with identical parts.
• Carry out repairs according to the instructions. On completion of repairs, carry out the
specified routine test on the device.
• Only Endress+Hauser Service may convert a certified device into a different certified
variant.
• Document all repair work and conversions.

14.1.3 Replacement of an electronics module

If an electronics module has been replaced, it is not necessary to perform a new basic setup
as the calibration parameters are stored in the HistoROM which is located in the housing.
However, after exchanging the main electronics module it may be necessary to record a
new mapping (interference echo suppression).

14.1.4 Replacement of a device

After a complete device or electronic module has been replaced, the parameters can be
downloaded into the instrument again in one of the following ways:
• Via the display module
Condition: The configuration of the old device has been saved in the display module
→  154.
• Via FieldCare
Condition: The configuration of the old device has been saved to the computer via
FieldCare.
You can continue to measure without carrying out a new setup. Only a linearization and a
tank map (interference echo suppression) have to be recorded again.

Additional information Meaning of the options

• Manual map
To be selected if the range of mapping is to be defined manually in the Mapping end
point parameter (→  113). In this case it is not necessary to confirm the distance.
• Distance ok
To be selected if the measured distance matches the actual distance. The device
performs a mapping.
• Distance unknown
To be selected if the actual distance is unknown. A mapping can not be performed in this
case.
• Distance too small
To be selected if the measured distance is smaller than the actual distance. The device
searches for the next echo and returns to the Confirm distance parameter. The distance
is recalculated and displayed. The comparison must be repeated until the displayed
distance matches the actual distance. After this, the recording of the map can be started
by selecting Distance ok.
• Distance too big 7)
To be selected if the measured distance exceeds the actual distance. The device adjusts
the signal evaluation and returns to the Confirm distance parameter. The distance is
recalculated and displayed. The comparison must be repeated until the displayed
distance matches the actual distance. After this, the recording of the map can be started
by selecting Distance ok.
• Tank empty
To be selected if the tank is completely empty. The device records a mapping covering
the complete measuring range as defined by the Tank/silo height parameter
(→  123). By default, Tank/silo height = Empty calibration.
Take into account that in case of conical outlets, for example, a measurement is only
possible up to the point at which the radar hits the bottom of the tank or silo. If the
Tank empty option is used, Empty calibration (→  109) and Tank/silo height may
not reach below this point as otherwise the empty signal is suppressed.
• Factory map
To be selected if the present mapping curve (if one exists) is to be deleted. The device
returns to the Confirm distance parameter and a new mapping can be recorded.
When operating via the display module, the measured distance is displayed together
with this parameter for reference purposes.
If the teaching procedure with the Distance too small option or the Distance too big
option is quit before the distance has been confirmed, a map is not recorded and the
teaching procedure is reset after 60 s.

Selection • Foam (>5cm/0,16ft)

• Changing DC values
• Small tanks (< 1m/3ft)

Factory setting None

Additional information "Foam (>5cm/0,16ft)" option

This option makes sure that no tank history is used which has been recorded while foam
was present at the surface and thus is no reliable map of the tank property. To achieve
this, the setting Evaluation mode = Long time history is deactivated.
The Foam (>5cm/0,16ft) option is only available for liquid applications (FMR50,
FMR51, FMR52, FMR53, FMR54).

"Changing DC values" option

A tank history which has been recorded with Evaluation mode = Long time history is
only valid for a fixed dielectric constant. The Changing DC values option disables the
setting Evaluation mode = Long time history and thus avoids wrong measuring values in
the case of a changing dielectric constant.
The Changing DC values option is only available for liquid applications (FMR50,
FMR51, FMR52, FMR53, FMR54).

"Small tanks (< 1m/3ft)" option

This option provides a simple possibility to reduce the echo width of the sensor module.
This enables an improved detection of superimposed echos - especially in the near field.
Internally, all paramters related to the echo width are adjusted by this option.
The Small tanks (< 1m/3ft) option is only available for liquid measurements with 26

Additional information Signals in the blocking distance are only evaluated if they have been outside the blocking
distance when the device was switched on and move into the blocking distance due to a
level change during operation. Signals which are already in the blocking distance when the
device is switched on, are ignored.
This behavior is only valid if the following two conditions are met:
• Expert → Sensor → Echo tracking → Evaluation mode = Short time history or Long

• Expert → Sensor → Gas phase comp. → GPC mode= On, Without correction or
External correction
If one of these conditions is not met, signals in the blocking distance will always be
ignored.
If required, a different behavior for signals in the blocking distance can be defined by

Additional information A total of 1000 measured values can be logged. This means:
• 1000 data points if 1 logging channel is used
• 500 data points if 2 logging channels are used
• 333 data points if 3 logging channels are used
• 250 data points if 4 logging channels are used
If the maximum number of data points is reached, the oldest data points in the data log
are cyclically overwritten in such a way that the last 1000, 500, 333 or 250 measured
values are always in the log (ring memory principle).
The logged data are deleted if a new option is selected in this parameter.

Logging interval 

Navigation  Diagnostics → Data logging → Logging interval

Factory setting 30.0 s

* Visibility depends on order options or device settings

Endress+Hauser 169
Operating menu Micropilot FMR51, FMR52 HART

Additional information This parameter defines the interval between the individual data points in the data log, and
thus the maximum loggable process time T log :
• If 1 logging channel is used: T log = 1000 ⋅ t log
• If 2 logging channels are used: T log = 500 ⋅ t log
• If 3 logging channels are used: T log = 333 ⋅ t log
• If 4 logging channels are used: T log = 250 ⋅ t log
Once this time elapses, the oldest data points in the data log are cyclically overwritten such
that a time of T log always remains in the memory (ring memory principle).
The logged data are deleted if this parameter is changed.

Example
When using 1 logging channel
• Tlog = 1000 ⋅ 1 s = 1 000 s ≈ 16.5 min
• Tlog = 1000 ⋅ 10 s = 1 000 s ≈ 2.75 h
• Tlog = 1000 ⋅ 80 s = 80 000 s ≈ 22 h
• Tlog = 1000 ⋅ 3 600 s = 3 600 000 s ≈ 41 d
