Technical Information
Micropilot M FMR250
Level-Radar
Smart Transmitter for continuous and non-contact level
measurement in solids.
Cost-effective 4 to 20 mA 2-wire technology.
Application
The Micropilot M performs continuous, non-contact
level measurement especially in powdery to granular
bulk solids. Additionally it can be used in liquids as well.
Dust, filling noises, temperature layers and gas
stratification do not affect measurement.
Typical areas of application are:
• Level measurement in tall silos with extremely dusty
bulk solids e.g. cement, raw meal or animal feed.
• Applications with high temperature requirements up
to 200 °C (392 °F), e.g. clinker or fly ash.
• Applications with highly abrasive bulk solids e.g.
ferrite.
The FMR250 with DN80 or DN100 horn antenna for all
standard applications, particularly also for small nozzle
sizes.
The FMR250 with DN200 parabolic antenna offers high
beam focussing of 4° and is thus ideal for applications
with many installations.

Micropilot M FMR250
Endress+Hauser 3
Function and system design
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) are not interpreted as level echo.
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
conditions. 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.

System integration via Fieldgate
Vendor Managed Inventory
By using Fieldgates to interrogate tank or silo levels remotely, suppliers of raw materials can provide their
regular customers with information about the current supplies at any time and, for example, account for them
in their own production planning. For their part, the Fieldgates monitor the configured level limits and, if
required, automatically activate the next supply. The spectrum of options here ranges from a simple purchasing
requisition via e-mail through to fully automatic order administration by coupling XML data into the planning
systems on both sides.
Remote maintenance of measuring equipment
Fieldgates not only transfer the current measured values, they also alert the responsible standby personnel, if
required, via e-mail or SMS. In the event of an alarm or also when performing routine checks, service
technicians can diagnose and configure connected HART devices remotely. All that is required for this is the
corresponding HART operating software (e.g. ToF Tool - FieldTool Package, FieldCare, ...) for the connected
device. Fieldgate passes on the information transparently, so that all options for the respective operating
software are available remotely. Some on-site service operations can be avoided by using remote diagnosis and
remote configuration and all others can at least be better planned and prepared.
L00-FXA520xx-14-00-06-en-009
Note!
The number of instruments which can be connected in mutidrop mode can be calculated by the "FieldNetCalc"
program. A description of this program can be found in Technical Information TI 400F (Multidrop Conncector
FXN520). The program is available form your Endress+Hauser sales organisation or in the internet at:

Input
Measured variable The measured variable is the distance between a reference point (refer to fig. on page 2) and a reflective surface
(i.e. medium surface).
The level is calculated based on the vessel height entered.The level can be converted into other units (volume,
mass) by means of a linearization (32 points).
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.
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.

Antenna type Application
FMR250-*4*... 3" (DN80)
FMR250-*5*... 4" (DN100)
The FMR250 with 3" (DN80) or 4" (DN100) horn antenna for all standard applications,
particularly also for small nozzle sizes.
To achieve an optimised signal strength it is recommended to use an antenna with as
large as possible diameter.
In small tanks in particular, an antenna extension should not be used wherever possible
to optimize dynamics at close range.
FMR250-*6*... 8"(DN200) The FMR250 with 8" (DN200) parabolic antenna offers high beam focussing of 4° and is
thus ideal for applications with many installations.

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.
The maximum measuring range can be increased in such applications by using a top target positioner
(see Page 16).
• 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 = 2" to 6" (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=16" (400 mm, see Fig.) to the tip of the antenna.

inputs and generates an output based on the configured
action. This block normally receives its inputs from AI
blocks. The block performs maximum, minimum, middle,
average and ‘first good’ signal selection.

Signal Charac-
terizer Block
The signal characterizer block has two sections, each
with an output that is a non-linear function of the respec-
tive input. The non-linear function is determined by a sin-
gle look-up table with 21 arbitrary x-y pairs.
40 ms standard
Integrator Block The Integrator Function Block integrates a variable as a
function of the time or accumulates the counts from a
Pulse Input block. The block may be used as a totalizer
that counts up until reset or as a batch totalizer that has a
setpoint, where the integrated or accumulated value is
compared to pre-trip and trip settings, generating discrete
signals when these settings are reached.

Operating conditions: Installation
Installation instructions 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.
Note!
If the tank wall is not smooth (corrugated metal,
welding seams, irregularities etc.) the distance from
the wall should be kept as large as possible. If
necessary, use a top target positioner to prevent
interference reflections from the tank 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 (see
Accessorieson page 39).
• 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 (see Beam angle
on Page 17).
• 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°.
• In particular, sensor alignment serves to:
– prevent interference reflections
– extend the maximum possible measuring range
in conical outlets.
• Metallic screens (3) mounted at a slope spread the
radar signals and can, therefore, reduce
interference echoes.

Measurement in a plastic tank
If the outer wall of the tank is made of a non-conductive material (e.g. GRP), microwaves can also be reflected
off interfering installations outside the signal beam (e.g. metallic pipes (1), ladders (2), grates (3), …). Therefore,
avoid such interfering installations in the signal beam.
L00-FMR250xx-17-00-00-xx-014
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 antenna type (beam angle α) and

Cleaning of the antenna The antenna can get contaminated, depending on the application. The emission and reception of microwaves
can 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
(EMC)
• Electromagnetic compatibility to EN 61326 and NAMUR recommendation EMC (NE 21). For details refer
to the declaration of conformity.
• A standard installation cable is sufficient if only the analogue signal is used. Use a screened cable when

The number of bolts has sometimes been reduced. The bolt-holes have been enlarged for adaption of
dimensions, therefore, the flange needs to be properly aligned to the counterflange before the bolts are
tightened. Dimensions are in inches (mm).

Human interface
Operation concept The display of the process value and the configuration of the Micropilot occur locally by means of a large 4-line
alphanumeric display with plain text information. The guided menu system with integrated help texts ensures
a quick and safe commissioning.
To access the display the cover of the electronic compartment may be removed even in hazardous area (IS and
XP).
Remote commissioning, including documentation of the measuring point and in-depth analysis functions, is
supported via the ToF Tool, the graphical operating software for E+H time-of-flight systems.
Display elements Liquid crystal display (LCD):
Four lines with 20 characters each. Display contrast adjustable through key combination.
L00-FMxxxxxx-07-00-00-en-001
The VU331 LCD display can be removed to ease operation by simply pressing the snap-fit (see graphic above).
It is connected to the device by means of a 20" (500 mm) cable.
The following table describes the symbols that appear on the liquid crystal display:
