1 Safety instructions
1.1 Designated use
The Micropilot M FMR250 is a compact level radar for the continuous, contactless measurement of
predominantly solids. The device can also be freely mounted outside closed metal vessels because
of its operating frequency of about 26 GHz and a maximum radiated pulsed energy of 1mW
(average power output 1 µW). Operation is completely harmless to humans and animals.
1.2 Installation, commissioning and operation
The Micropilot M has been designed to operate safely in accordance with current technical, safety
and EU standards. If installed incorrectly or used for applications for which it is not intended,
however, it is possible that application-related dangers may arise, e.g. product overflow due to
incorrect installation or calibration. For this reason, the instrument must be installed, connected,
operated and maintained according to the instructions in this manual: personnel must be authorised
and suitably qualified. The manual must have been read and understood, and the instructions
followed. Modifications and repairs to the device are permissible only when they are expressly
approved in the manual.
1.3 Operational safety
1.3.1 Hazardous areas
Measuring systems for use in hazardous environments are accompanied by separate "Ex
documentation", which is an integral part of this Operating Manual. Strict compliance with the

3.3.2 Engineering hints
Orientation
• Recommended distance (1) wall – outer
edge of nozzle: ~1/6 of vessel diameter.
However, the device should not, under any
circumstances, be mounted less than 20 cm/
8“ from the vessel wall.
• Not in the centre (3), interference can cause
signal loss.
• Not above the fill stream (4).
• It is recommended to use a weather
protection cover (2) in order to protect the
transmitter from direct sun or rain. Assembly
and disassembly is simply done by means of a
tension clamp (→Chap. 8 on Page 64).
• In extremely dusty applications, the
integrated air purge connection can prevent
clogging of the antenna.

Vessel installations
• Avoid any installations (1), like limit switches,
struts, etc., inside the signal beam (refer to
beam angle see "Beam angle" on Page 16).
• Symmetrical installations (2), i.e. reinforcing
rings, heating coils, etc., can also interfere
with the measurement.
Optimization options
• Antenna size: the bigger the antenna, the
smaller the beam angle, the less interference
echoes.
• Mapping: the measurement can be optimized
by means of electronic suppression of
interference echoes.
• Antenna alignment: refer to "Optimum
mounting position"
• In devices with top target positioner, the
sensor can be optimally aimed within the
vessel and/or interference reflections can be
avoided.
The max. angle β is ±15°.
Please contact Endress+Hauser for further
information.

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

Measuring conditions
• The measuring range begins, where the beam hits the vessel bottom. Particularly with dish
bottoms or conical outlets the level cannot be detected below this point.
• In case of media with a low dielectric constant (groups A and B), the vessel bottom can be visible
through the medium at low levels. In order to guarantee the required accuracy in these cases, it
is recommended to position the zero-point at a distance C =50...150 mm above the vessel bottom
(see Fig.).
• In principle it is possible to measure up to the tip of the antenna with FMR250. However, due to
considerations regarding abrasion and build-up, the end of the measuring range should not be
chosen any closer than A=400 mm (see Fig.) to the tip of the antenna.
• The smallest possible measuring range B=500 mm (see Fig.).

Measuring range
The usable measuring range depends on the size of the antenna, the reflectivity of the medium, the
mounting location and eventual interference reflections. The maximum configurable range is 70 m
(229 ft) for Micropilot M FMR250.
To achieve an optimised Signal strength it is recommended to use an antenna with as large as
possible diameter (DN200/8" parabolic antenna, DN100/4" horn).
Reduction of the max. possible measuring range through:
• Media with poor reflection properties (= small DC). For examples refer to table 1.
• Angle of repose.
• Extremely loose surfaces of bulk solids, e.g. bulk solids with low bulk weight for pneumatic filling.
• Build-up, above all of moist products.
Table 1:
The following table describes the media groups and the dielectric constant εr.
The respective lower group applies for very loose or loosened bulk solids.

5.1.1 General structure of the operating menu
The operating menu is made up of two levels:
•Function groups (00, 01, 03, …, 0C, 0D): The individual operating options of the instrument
are split up roughly into different function groups. The function groups that are available include,
e.g.: "basic setup", "safety settings", "output", "display", etc.
•Functions (001, 002, 003, …, 0D8, 0D9): Each function group consists of one or more
functions. The functions perform the actual operation or parameterisation of the instrument.
Numerical values can be entered here and parameters can be selected and saved. The available

5.3.3 Factory settings (Reset)
"Caution!
A reset sets the instrument back to the factory settings. This can lead to an impairment of the
measurement. Generally, you should perform a basic setup again following a reset.
A reset is only necessary:
• if the instrument no longer functions
• if the instrument must be moved from one measuring point to another
• if the instrument is being de-installed /put into storage/installed
User input ("reset" (0A3)):
• 333 = customer parameters
333 = reset customer parameters
This reset is recommended whenever an instrument with an unknown 'history' is to be used in an
application:
• The Micropilot is reset to the default values.
• The customer specific tank map is not deleted.
• A linearisation is switched to "linear" although the table values are retained. The table can be
reactivated in the "linearisation"(04) function group.
List of functions that are affected by a reset:
The tank map can also be reset in the "mapping"(055) function of the "extended calibr."(05)
function group.
This reset is recommended whenever an instrument with an unknown 'history' is to be used in an
application or if a faulty mapping was started:
• The tank map is deleted. The mapping must be recommenced.

5.4 Display and acknowledging error messages
Type of error
Errors that occur during commissioning or measuring are displayed immediately on the local
display. If two or more system or process errors occur, the error with the highest priority is the one
shown on the display.
The measuring system distinguishes between two types of error:
•A (Alarm):
Instrument goes into a defined state (e.g. MAX 22 mA)
Indicated by a constant symbol.
(For a description of the codes, see Page 67)
•W (Warning):
Instrument continue measuring, error message is displayed.
Indicated by a flashing symbol.
(For a description of the codes, see Page 67)
•E (Alarm / Warning):
Configurable (e.g. loss of echo, level within the safety distance)
Indicated by a constant/flashing symbol.
(For a description of the codes, see Page 67)
5.4.1 Error messages
Error messages appear as four lines of plain text on the display. In addition, a unique error code is
also output. A description of the error codes is given on Page 67.
•The "diagnostics" (0A) function group can display current errors as well as the last errors that
occurred.
• If several current errors occur, use O or S to page through the error messages.
• The last occurring error can be deleted in the "diagnostics" (0A) function group
with the funktion"clear last error" (0A2).

!Note!
• Further information on the HART handheld unit is given in the respective operating manual
included in the transport bag of the instrument.
5.5.2 ToF Tool operating program
The ToF Tool is a graphical operating software for instruments from Endress+Hauser that operate
based on the time-of-flight principle. It is used to support commissioning, securing of data, signal
analysis and documentation of the instruments. It is compatible with the following operating
systems: WinNT4.0, Win2000 and WinXP.
The ToF Tool supports the following functions:
• Online configuration of transmitters
• Signal analysis via envelope curve
• Tank linearisation
• Loading and saving of instrument data (Upload/Download)
• Documentation of measuring point

Micropilot M FMR250 with HART/4...20 mA Commissioning
Endress + Hauser 43
The basic setup is sufficient for successful commissioning in most applications. Complex measuring
operations necessitate additional functions that the user can use to customise the Micropilot as
necessary to suit his specific requirements. The functions available to do this are described in detail
in the BA291F.
Comply with the following instructions when configuring the functions in the "basic setup" (00):
• Select the functions as described on Page 31.
• Some functions can only be used depending on the parameterisation of the instrument. For
example, the pipe diameter of a stilling well can only be entered if "stilling well" was selected
beforehand in the "tank shape" (002) function.
• Certain functions (e.g. starting an interference echo mapping (053)) prompt you to confirm your
data entries. Press O or S to select "YES" and press F to confirm. The function is now started.
• If you do not press a key during a configurable time period (→ function group "display"(09)),
an automatic return is made to the home position (measured value display).
!Note!
• The instrument continues to measure while data entry is in progress, i.e. the current measured
values are output via the signal outputs in the normal way.
• If the envelope curve mode is active on the display, the measured values are updated in a slower
cycle time. Thus, it is advisable to leave the envelope curve mode after the measuring point has
been optimised.
• If the power supply fails, all preset and parameterised values remain safely stored in the EEPROM.
"Caution!
All functions are described in detail, as is the overview of the operating menu itself, in the manual
“Description of the instrument functions − BA291F”, which is found on the enclosed CD-
ROM.
!Note!
The default values of the parameters are typed in boldface.

6.4.2 Envelope curve with VU331
After the basic setup, an evaluation of the measurement with the aid of the envelope curve
("envelope curve"(0E) function group) is recommended.
Function "plot settings" (0E1)
Select which information will be displayed in the LCD:
•envelope curve
• env.curve+FAC (on FAC see BA291F)
• env.curve+cust.map (i.e. customer tank map is also displayed)
Function "recording curve" (0E2)
This function defines whether the envelope curve is read as a
•single curve
or
• cyclic.
!Note!
If the cyclical envelope curve is active in the display, the measured value is refreshed in a slower
cycle time. It is therefore recommended to exit the envelope curve display after optimising the
measuring point.
!Note!
An orientation of the Micropilot can help to optimise measurement in applications with very weak
level echos or strong interference echos by increasing the useful echo/reducing the interference
echo (see "Orientation of the Micropilot" on Page 73).
When using the Wave Guide antenna: No orientation is required!

6.5.1 Envelope curve with the ToF Tool
After the basic setup, an evaluation of the measurement using the envelope curve is recommended.
L00-FMR250xx-20-00-00-en-008
!Note!
If the level of echo is very weak or there is a heavy interference echo, an orientation of the
Micropilot can help optimise the measurement (increase of the useful echo/reduction of the
interference echo) (see "Orientation of the Micropilot" on Page 73).
When using the Wave Guide antenna: No orientation is required!
6.5.2 User-specific applications (operation)
For details of setting the parameters of user-specific applications, see separate documentation
BA291F/00/en "Description of the instrument functions for Micropilot M" on the enclosed CD-
ROM.
Micropilot M FMR250 with HART/4...20 mA Maintenance
Endress + Hauser 63
7 Maintenance
The Micropilot M measuring instrument requires no special maintenance.
Exterior cleaning
When cleaning the exterior of measuring devices, always use cleaning agents that do not attack the
surface of the housing and the seals.
Replacing seals
The process seals of the sensors 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.
Repairs
The Endress+Hauser repair concept assumes that the measuring devices have a modular design and
that customers are able to undertake repairs themselves. Spare parts are contained in suitable kits.
They contain the related replacement instructions. All the spare parts kits which you can order from
Endress+Hauser for repairs to the Micropilot M are listed with their order numbers on and . Please
contact Endress+Hauser Service for further information on service and spare parts.
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
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 our 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.
Replacement
After a complete Micropilot or electronic module has been replaced, the parameters can be
downloaded into the instrument again via the communication interface. Prerequisite to this is that
the data were uploaded to the PC beforehand using the ToF Tool / FieldCare.
Measurement can continue without having to carry out a new setup.
• You may have to activate linearisation (see BA291F on the enclosed CD-ROM)
• You may need to record the tank map again (see Basic Setup)
After an antenna component or electronic has been replaced, a new calibration must be carried out.
This is described in the repair instructions.

9.5 Orientation of the Micropilot
For orientation a marker is found on the flange or threaded boss of the Micropilot. During
installation this must be oriented as follows (see Page 11):
• In tanks: to the vessel wall
• In stilling wells: to the slots
• In bypass pipes: vertical to the tank connectors
• When using the Wave Guide antenna no orientation is required!
After commissioning the Micropilot, the echo quality indicates whether a sufficiently large
measuring signal is obtained. If necessary, the quality can be optimised later. Vice versa, the
presence of an interference echo can be used to minimise this by optimum orientation. The
advantage of this is that the subsequent tank mapping uses a somewhat lower level that causes an
increase in the strength of the measuring signal.
Proceed as follows:
#Warning!
Subsequent alignment can lead to personal injury. Before you unscrew or loosen the process
connection, make sure that the vessel is not under pressure and does not contain any injurious
substances.
1. It is best to empty the container so that the bottom is just covered. However, alignment can be
carried out even if the vessel is empty.
2. Optimisation is best carried out with the aid of the envelope graph in the display or the
ToF Tool.
3. Unscrew the flange or loosen the threaded boss by a half a turn.
4. Turn the flange by one hole or screw the threaded boss by one eighth of a turn. Note the echo
quality.
5. Continue to turn until 360° is reached.
6. Optimum alignment:

If necessary, replace the seal.
8. Carry out tank mapping, see Page 53.
Top target positioner - optional
Using top target positioner it is possible to tilt the antenna axis by up to 15° in all directions. The
top target positioner is used for the optimum alignment of the radar beam with the bulk solids
surface.

9.7 Return
The following procedures must be carried out before a transmitter is sent to Endress+Hauser e.g.
for repair or calibration:
• Remove all residue which may be present. Pay special attention to the gasket grooves and crevices
where fluid may be present. This is especially important if the fluid is dangerous to health, e.g.
corrosive, poisonous, carcinogenic, radioactive, etc.
• Always enclose a duly completed "Declaration of contamination" form (a copy of the “Declaration
of contamination” is included at the end of this operating manual). Only then can Endress
+Hauser transport, examine and repair a returned device.
• Enclose special handling instructions if necessary, for example a safety data sheet as per EN 91/
155/EEC.
Additionally specify:
• An exact description of the application.
• The chemical and physical characteristics of the product.
• A short description of the error that occurred (specify error code if possible)
• Operating time of the device.
9.8 Disposal
In case of disposal please seperate the different components according to their material consistence.

10 Technical data
10.1 Additional technical data
10.1.1 Input
Measured variable The measured variable is the distance between a reference point and a reflective surface (i.e.
medium surface).
The level is calculated based on the tank height entered.
The level can be converted into other units (volume, mass) by means of a linearization.
10.1.2 Output
Output signal 4…20 mA with HART protocol
Signal on alarm Error information can be accessed via the following interfaces:
•Local display:
– Error symbol (see Page 34)
– Plain text display
• Current output
• Digital interface
Linearization The linearization function of the Micropilot M allows the conversion of the measured value into any
unit of length or volume. Linearization tables for calculating the volume in cylindrical tanks are pre-
programmed. Other tables of up to 32 value pairs can be entered manually or semi-automatically.
10.1.3 Auxiliary energy
Ripple HART 47...125 Hz: Uss = 200 mV (at 500 Ω)
Max. noise HART 500 Hz...10 kHz: Ueff = 2.2 mV (at 500 Ω)
10.1.4 Performance characteristics
Reference operating
conditions
• temperature = +20 °C (68 °F) ±5 °C (9 °F)
• pressure = 1013 mbar abs. (14.7 psia) ±20 mbar (0.3 psi)
• relative humidity (air) = 65 % ±20%
•ideal reflector
• no major interference reflections inside the signal beam
Maximum measured error Typical statements for reference conditions, include linearity, repeatability, and hysteresis:
• up to 1 m: ±30 mm
• ex 1 m: ±15 mm (or 0.04% of measuring range, whatever is larger)
Resolution Digital / analog in % 4…20 mA
• FMR250: 1mm / 0.03 % of measuring range
Reaction time The reaction time depends on the parameter settings (min. 1 s). In case of fast level changes, the
instrument needs the reaction time to indicate the new value.

Cleaning of the antenna The antenna can get contaminated, depending on the application. The emission and reception of
microwaves can thus eventually be hindered. The degree of contamination leading to an error
depends on the medium and the reflectivity, mainly determined by the dielectric constant εr. If the
medium tends to cause contamination and deposits, cleaning on a regular basis is recommended.
Care has to be taken not to damage the antenna in the process of a mechanical or hose-down
cleaning (eventually air purge connection). The material compatibility has to be considered if
cleaning agents are used!
The maximum permitted temperature at the flange should not be exceeded.
Electromagnetic compatibility • Interference Emission to EN 61326, Electrical Equipment Class B
• Interference Immunity to EN 61326, Annex A (Industrial) and NAMUR Recommendation
NE 21 (EMC)
• A standard installation cable is sufficient if only the analogue signal is used. Use a screened cable
when working with a superimposed communications signal (HART).

11.2 Description of functions
!Note!
A detailed description of the function groups, functions and parameters is given in the
documentation BA291F/00/en "Description of the instrument functions of the Micropilot M" on
the enclosed CD-ROM.
Micropilot M FMR250 with HART/4...20 mA Appendix
Endress + Hauser 89
11.3 Function and system design
11.3.1 Function (Measuring principle)
The Micropilot is a "downward-looking" measuring system, operating based on the time-of-flight
method. It measures the distance from the reference point (process connection) to the product
surface. Radar impulses are emitted by an antenna, reflected off the product surface and received
again by the radar system.
L00-FMR250xx-15-00-00-en-001
Input
The reflected radar impulses are received by the antenna and transmitted into the electronics. A
microprocessor evaluates the signal and identifies the level echo caused by the reflection of the radar
impulse at the product surface. The unambiguous signal identification is accomplished by the
PulseMaster® software, based on many years of experience with time-of-flight technology.
The distance D to the product surface is proportional to the time of flight t of the impulse:
D = c · t/2,
with c being the speed of light.
Based on the known empty distance E, the level L is calculated:
L = E – D
Refer to the above figure for the reference point for "E".
The Micropilot is equipped with functions to suppress interference echoes. The user can activate
these functions. They ensure that interference echoes (i.e. from internals and struts seams) are not
interpreted as level echo.

Appendix Micropilot M FMR250 with HART/4...20 mA

Output
The Micropilot is commissioned by entering an empty distance E (=zero), a full distance F (=span)
and an application parameter. The application parameter automatically adapts the instrument to the
process cond.. The data points “E” and “F” correspond with 4mA and 20mA for instruments with
current output. They correspond with 0 % and
100 % for digital outputs and the display module.
A linearization with max. 32 points, based on a table entered either manually or
semi-automatically, can be activated locally or remotely. This function provides a measurement in
engineering units and a linear output signal for spheres, horizontal cylindrical tanks and vessels with
conical outlet.
11.3.2 Equipment architecture
Stand-alone
The instrument provides a 4…20 mA output with HART protocol.
4…20 mA output with HART protocol
The complete measuring system consists of:
L00-FMR2xxxx-14-00-06-en-001
If the HART communication resistor is not built into the supply unit, it is necessary to insert a
communication resistor of 250 Ω into the 2-wire line.
