1 Safety instructions

1.1 Designated use

The Micropilot M is a compact radar level transmitter for the continuous, contactless measurement
of liquids, pastes, sludge and 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 1 mW (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 and process safety

Alternative monitoring measures must be taken to ensure operational safety and process safety
during configuration, testing and maintenance work on the device.

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
installation instructions and ratings as stated in this Additional documentation is mandatory.

• Ensure that all personnel are suitably qualified.

• Observe the specifications in the certificate as well as national and local regulations.

1.3.1 FCC approval

This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference received, including interference that may cause
undesired operation.

Caution!

"

Changes or modifications not expressly approved by the part responsible for compliance could void
the user’s authority to operate the equipment.

3.3.2 Engineering hints

Orientation

• Recommended distance (1) wall – outer
edge of nozzle: ~1/6 of tank diameter.

Nevertheless the device should not be
installed closer than 15 cm (5.91 in) to the
tankwall.

• 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 (→ ä 65, "Accessories").

1

234

Tank installations

• Avoid any installations (1), like limit switches,
temperature sensors, etc., inside the signal
beam (→ ä 16, "Beam angle").

• Symmetrical installations (2), i. e. vacuum
rings, heating coils, baffles, 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: "Installation in tank (free
space)", → ä 21

• Stilling well: a stilling well can always be used
to avoid interference.

• 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, there should be no such interfering installations in the signal beam.

Measuring conditions in liquids

Note!

• In case of boiling surfaces, bubbling or tendency for foaming, use FMR230 or FMR231.
Depending on its consistence, foam can either absorb microwaves or reflect them off the foam
surface. Measurement is possible under certain conditions.

• In case of heavy steam development or condensate the max. measuring range of FMR240 may
decrease depending on density, temperature and composition of the steam → use FMR230 or
FMR231.

• For the measurement of absorbing gases such as ammonia NH

or some fluorocarbons 1),

please use FMR230 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 case of media with a low dielectric constant (groups A and B), 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 Fig.)
above the tank bottom in these applications.

• In principle it is possible to measure up to the tip of the antenna with FMR230/231/240.
However, due to considerations regarding corrosion and build-up, the end of the measuring range
should not be chosen any closer than A (see Fig.) to the tip of the antenna.
For FMR244/245, the end of measuring range should not be chosen closer than A (see Fig.) to
the tip of the antenna, especially if there is development of condensate.

• The smallest possible measuring range B depends on the antenna version (see Fig.).

• The tank diameter should be greater than D (see Fig.), the tank height at least H (see Fig.).

Measuring conditions in solids

• The measuring range begins, where the beam hits the bottom. Particularly with 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 Technical Information TI00345F/00/EN).

• In case of media with a low dielectric constant (groups A and B), the 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 above the bottom (see Fig.).

• In principle it is possible to measure up to the tip of the antenna with the Micropilot M. However,
due to considerations regarding abrasion and build-up and depending on the orientation of the
product surface (angel of repose), the end of the measuring range should be at a distance of A, see
Fig. If required, and if some conditions (high DC value, flat angle of repose) are met, shorter
distances can be achieved.

Measuring range in liquids

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:

• 40 m (131 ft) for basic version

• 70 m (230 ft) with additional option F (G), → ä 7, "ordering information"
The following tables describe the groups of media as well as the achievable measuring range as a

function of application and media group. If the dielectric constant of a medium is unknown, it is
recommended to assume media group B to ensure a reliable measurement.

Media group DC (εr) Examples

A 1.4 to 1.9 non-conducting liquids, e. g. liquefied gas

B 1.9 to 4 non-conducting liquids, e. g. benzene, oil, toluene, …

C 4 to 10 e. g. concentrated acids, organic solvents, esters, aniline, alcohol, acetone, …

D > 10 conducting liquids, e. g. aqueous solutions, dilute acids and alkalis

1) Treat Ammonia NH3 as a medium of group A, i. e. use FMR230 in a stilling well.

1)

Measuring range in solids

The FMR244 with 80 mm (3") antenna or FMR240 with 100 mm (4") horn antenna and additional
option F (= advanced dynamics) is also suited for solid applications. The usable measuring range
depends on the reflection properties of the medium, the mounting position and interference
reflections which may be present. The maximum configurable measuring range for the Micropilot
M FMR240 with 100 mm (4") horn antenna and additional option F (= advanced dynamics) is
30 m (98 ft) in solid applications. It is recommended to use the variable flange seal for alignment
(see Technical Information TI00345F/00/EN).

Reduction of the max. possible measuring range through:

• Media with poor reflection properties (= small DC). For examples refer to table below.

• 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.

The following table describes the media groups and the dielectric constant

Standard installation

For installations in a stilling well, follow the engineering hints (→ ä 14) and note the following
points:

• Marker is aligned toward slots.

• Install the device using the threaded boss (AF60) only. Observe the max. torque of
20 Nm (14.75 lbf ft).

• After mounting, the housing can be turned 350° in order to simplify access to the display and the
terminal compartment.

• Measurements can be performed through an open full bore ball valve without any problems.

Recommendations for the stilling well

At the construction of a stilling well, please note the following points:

• Metal (no enamel coating, plastic coating on request).

• Constant diameter.

• Stilling well diameter not larger than antenna diameter.

• Weld seam as smooth as possible and on the same axis as the slots.

• Slots offset 180° (not 90°).

• Slot width respectively diameter of holes max. 1/10 of pipe diameter, de-burred. Length and
number do not have any influence on the measurement.

• At any transition (i. e. when using a ball valve or mending pipe segments), no gap may be created
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 stainless steel 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.

Operation Micropilot M FMR244 HART 4 to 20 mA

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
functions of the “basic setup” (00) function group include, e. g.: "tank shape" (002),
"medium property" (003), "process cond." (004), "empty calibr." (005), etc.

If, for example, the application of the instrument is to be changed, carry out the following
procedure:

1. Select the “basic setup” (00) function group.

2. Select the "tank shape" (002) function (where the existing tank shape is selected).

5.1.2 Identifying the functions

For simple orientation within the function menus (→ ä 86), for each function a position is shown
on the display.

L00-FMRxxxxx-07-00-00-en-005

The first two digits identify the function group:

• basic setup 00

• safety settings 01

• linearisation 04

. . .

The third digit numbers the individual functions within the function group:

• basic setup 00 → • tank shape 002

• medium property 003

• process cond. 004

. . .

Hereafter the position is always given in brackets (e.g. "tank shape" (002)) after the described
function.

Micropilot M FMR244 HART 4 to 20 mA Commissioning

Caution!

"

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 BA00291F/00/EN.

Comply with the following instructions when configuring the functions in the "basic setup" (00):

• Select the functions as described, → ä 33.

• 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

• 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.

• All functions are described in detail, as is the overview of the operating menu itself, in the manual
"BA00291F - Description of the instrument functions", which is found on the enclosed
CD-ROM.

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 (→ ä 75, "Spare Parts"). 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 FieldCare.
Measurement can continue without having to carry out a new setup.

• You may have to activate linearisation (see BA00291F/00/EN 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.

Micropilot M FMR244 HART 4 to 20 mA Trouble-shooting

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 (→ ä 10):

• In tanks: to the vessel wall

• In stilling wells: to the slots

• In bypass pipes: vertical to the tank connectors
After commissioning the device, 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
FieldCare.

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:

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)

• If necessary, give the error code.

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 (32 points).

Operating frequency K-band

Up to 8 Micropilot M transmitters can be installed in the same tank because the transmitter pulses
are statistically coded.

• For max. measuring range = 40 m (131 ft)
– to 10 m (33 ft): ±3 mm (±0.12 in)
– ex 10 m (33 ft): ±0.03 % of measuring range

• For max. measuring range = 70 m (230 ft)
– to 1 m (3.3 ft): ±30 mm (±1.18 in)
– ex 1 m (3.3 ft): ±15 mm (±0.59 in) or 0.04 % of measuring range, whatever is larger

Resolution Digital / analog in % 4…20 mA: 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.

Influence of ambiente
temperature

The measurements are carried out in accordance with EN61298-3:

• Digital output HART:
– average T

: 2 mm (0.08 in) /10 K, max. 5 mm (0.2 in) over the entire temperature range

K

-40 °C to +80 °C (-40 to +176 °F)

• Current output (additional error, in reference to the span of 16 mA):
– Zero point (4 mA)

average T

: 0,03 %/10 K, max. 0,45 % over the entire temperature range -40 °C to +80 °C

K

: 0,09 %/10 K, max. 0,95 % over the entire temperature range -40 °C to +80 °C

K

(-40 to +176 °F)

Effect of gas phase High pressures reduce the propagation velocity of the measuring signals in the gas/vapor above the

fluid. This effect depends on the gas/vapor and is particularly large for low temperatures. This
results in a measuring error that gets bigger as the distance increases between the device zero point
(flange) and product surface. The following table illustrates this measured error for a few typical
gases/vapors (with regard to the distance; a positive value means that too large a distance is being
measured):

• FMR230/231, FMR240/244/245 with 40 mm (1½") antenna:
20 to 2000 Hz, 1 (m/s²)²/Hz

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
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 connection for cleaning liquid). The material compatibility has to be considered
if cleaning agents are used! The maximum permitted temperature at the flange should not be
exceeded.

r. If the

ε

Electromagnetic compatibility • Electromagnetic compatibility in accordance with all the relevant requirements of the EN61326

series and NAMUR recommendation (NE21). For details refer to the Declaration of Conformity.
Maximum deviation < 0.5 % of the span.

• 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).

Process temperature range /
Process pressure limits

Note!
The specific range may be reduces by the selected process condition. The pressure rating (PN)
specified on the flanges refers to a reference temperature of 20 °C (68 °F), for ASME flanges to
100 °F. Observe pressure temperature dependency.
The pressure values permitted at higher temperatures can be found in the following standards:

• EN1092-1: 2001 Tab. 18
With regard to their temperature stability properties, the materials 1.4404 and 1.4435 are
grouped under 13E0 in EN1092-1 Tab. 18. The chemical composition of the two materials can
be identical.
