principle
BA171Y06
max. level
Micropilot is a "downward looking" time-of-flight system which measures the distance
from the probe mounting (top of the tank) to the surface of the process medium.
Short microwave pulses are beamed by the antenna towards the product, reflected by
its surface and detected by the same arrangement.
An inactive length at the start of the rod antenna delays the launch of the pulse for a
distance of 100 mm or 250 mm, ensuring that condensation or build-up in the mounting
nozzle does not affect the measurement.
Input
The reflected microwaves are detected by the antenna and passed on to the electronics.
Here a microprocessor evaluates the signal and identifies the echo produced by the
reflection of the beam at the product surface. The algorithms used for signal processing
are based on many years of experience in time-of-flight measurement.
The distance D to the product surface is proportional to the time-of-flight of the microwave
pulse t:
D = c • t/2
where c is the speed of propagation
Since the empty distance E is known to the system, it is a simple matter to calculate the
level L:
L=E–D
The datum point for "E" is the bottom face of the process connection.
Micropilot has an echo suppression function which can be activated by the user. This
prevents interference echoes, e.g. caused by fittings within the beam, from being
interpreted as the level echo.
Output
Micropilot is calibrated by entering the empty distance E, the full distance F and an
application parameter, which automatically tunes the instrument to the measuring
conditions.
For versions with current output, the points "E" and "F" correspond to 4 mA and 20 mA,
for digital outputs and the display to 0% and 100% level.

Micropilot FMR 231
Chapter 1 Introduction
A linearisation function, based on a manually or semi-automatically entered table, can
be activated locally at the display unit or via the foreign system interface. This allows
measurement in customer units and provides a linear output current for spherical vessels,
horizontal cylinders and tanks with conical outlet.
The accuracy of Micropilot FMR 231 is dependent upon the set measuring range and
material being measured, see Technical Data. Under reference conditions it is capable
of measuring to an accuracy of ±15 mm up to a measuring range of 10 m and ±0.15%
of the range end-value of measuring ranges from 10 m to 20 m..
Accuracy
The measuring range depends upon the conditions in the tank and the product to be
measured. Table 1.2 describes the product classes, Table 1.3 the measuring range as
a function of the application and measuring conditions.
Measuring range
In order to ensure the highest accuracy for Class B, we recommend that
• the empty distance "E" should be 30 cm above the tank bottom.
Class A products can be measured in bypass pipes using the FMR 230V horn antenna,
see operating manual BA 197F.

Examples
A
Non-conducting liquids, e.g. propane, buthane etc.

The Micropilot is a loop-powered transmitter with 4...20 mA analogue output and
superimposed HART signal. Note the following before connecting up:
General notes
Caution!
• The power supply rating must correspond to that on the nameplate.
• Turn off the power before connecting up.
• Connect the external ground terminal of the transmitter to the plant grounding
system before connecting up.
• Always tighten the locking screw, since this connects the antenna to the ground
potential of the housing.
If the measuring system is to be installed in a hazardous area, local regulations, national
guidelines and the specifications in the certificate are to be observed.The specified cable
gland must be used.
Hazardous areas
For certified transmitters, the explosion protection is realised as follows:
• Housing F12: EEx ia.
Warning!
The power supply must be intrinsically safe.
• Housing T12: EEx e m.
The housing must be integrated into the plant grounding system.
The power must be switched off before the connection compartment is opened.
The electronics and current output are galvanically isolated from the antenna circuit.
Connection
Connect up the Micropilot as follows:
• Switch off power.
• Unscrew lid of housing or connection compartment.
• For F12 housing:
If appropriate, remove VU 330.
Remove cover plate to connection compartment.

For the F12 housing, the operating elements are located within the transmitter housing
and can be operated when the cover is open. The T12 housing has a separate display
compartment which also can be opened in hazardous areas. The Micropilot has four
keys and an LED.
• The LED flashes when an entered value is registered as well as during the
suppression of interference echoes. During operation it remains off.
• The device keys allow the basic calibration of the Micropilot, but are deactivated
when the operating and display module VU 330 is connected.
Operation without the

Off-line operation
Commuwin also allows the Micropilot to be configured off-line. After all parameters have
been entered, the file generated can be loaded into the connected Micropilot. This can
now be commissioned by simply running the echo suppression procedure.
Up-/Download
This function allows the parameters of an already configured Micropilot FMR 231 to be
loaded and stored in Commuwin II. If several Micropilots (with the same software version)
have to be configured in the same way, the parameters can now be downloaded into the
devices. In this case as well, an echo suppression must be made when the devices are
commissioned.
It is not possible to up and download parameters between Micropilots with different
software versions.

Calibration outside tank using
device keys
An on-site calibration without the operating and display module VU 330 requires a defined
level echo. In order to avoid the danger of acquiring an interference echo from a fitting
as the zero point, it is recommended that the calibration be made outside the tank along
a suitable test path.
Test path
• The length of the test path must correspond to the required empty distance "E".
• A suitable reflector, e.g. a flat wall, must be available.
• The Micropilot is pointed at the wall about 1.5 m above the ground.
• The datum point for the empty distance

Linearisation mode
Micropilot FMR 231
Linearisation
A linearisation describes the relationship between level and the tank volume or product
weight and allows a measurement in technical units, e.g. metres, hectolitre, tonnes etc.
Afterwards, the measured value is displayed in the selected units in V0H0 and the
analogue output is proportional to the volume or weight. The table below lists the
linearisation modes.

Semi-automatic entry
In the case of semi-automatic entry, the tank is filled in stages. The
device automatically displays the level, the associated volume is
entered manually.
5
Linear relationship
Factory setting. The relationship between the technical units and
level is linear. By entering the max. volume or weight, the measured
value is output in the technical units chosen by the user.
In addition, V2H0 offers the functions:
1
Activate table
The entered linearisation table only comes into effect after it has
been activated.
4
Delete table
Before a new linearisation table is entered, any previously active
table must be deleted. On deletion the linearisation mode is
automatically set to linear.
During entry of the table, an error message is generated and the device indicates an
alarm. After the curve has been entered, it is checked for plausibility. The following
warnings and alarms can appear.

V3H5
Window suppression
Defines a distance measured from the datum point in
which no echoes are measured. It is used for suppressing
strong echoes in the immediate vicinity of the antenna,
see Chapter 7.7.
The default setting extends to the tip of the antenna.
A smaller distance cannot be entered.
V8H3
Delay on lost echo
If the echo is lost, alarm E641 is output. V8H3 determines
the time which elapses between the loss of the echo and
the response of the Micropilot. Default = 30 s.
V8H5
In safety distance
0: Warning
1: Alarm
2: Alarm, self-holding
3: Reset 2
A safety zone extends 10 cm in front of the window
suppressiion zone. This is to warn, that if the level
continues to rise, the measurement will become invalid. If
product enters the safety zone, the Micropilot responds
according to the setting in V8H5:
0: Warning E643 is output: the device continues to
measure
1: Alarm E643 is output: measurement is suspended until
the product leaves the safety zone.
2: Alarm E643 is output: measurement is suspended until
the alarm is acknowledged.

When the plausibility check is activated, the current level
is checked against the previous level, in order to establish
whether the value is plausible .If this is not the case, error

Application parameters
The height is the principle element in determining the type of tank, the speed of level
changes and the conditions at the product surface. It also affects the mounting position,
which in turn influences on the generation of multiple echoes when the product surface
is calm..
Height
The first echo factor directly affects the signal evaluation and ensures that the level echo
is correctly identified in the presence of multiple echoes. The factor can be set in V3H4
(0: Minimum, 1 = Medium, 2 = Maximum). A central mounting position in the tank, a
domed tank top and a calm product surface all favour the production of multiple echoes.
First echo factor
The tank bottom recognition function ensures reliable measurement in the following
cases:
Tank bottom recognition
• The tank has a dished bottom. If microwaves are reflected from the tank bottom,
e.g. when the tank is completely empty, then the curvature causes them to be
deflected towards the tank wall. This results in an increase in the time-of-flight,
and hence of the apparent distance to the level echo. A negative level would be
displayed. The tank bottom recognition function recognises this state of affairs
and displays the level zero.
• The liquid has a low dielectric constant (Class A and B) and the surface is calm.
Under these conditions a portion of the microwaves penetrate the surface. When
the tank is almost empty, it is possible that these microwaves are reflected from
its bottom to produce a strong, somewhat delayed echo. A negative level would
be displayed. The tank bottom recognition function recognises this state of affairs
and displays the true level.

communication (operating and display module VU 330, DXR 275 or Commuwin II), the
echo quality cannot be checked.
For reliable measurement the echo quality should be:
• at least 10 dB or 3 segments,
• better is 20 dB or 4 segments.
The probability that the echo will be lost when measuring conditions change (E641), e.g.
waves or large measuring ranges, increases with decreasing quality.
Better quality can be attained by exact alignment (turning the process connection) during
installation or a change of mounting position.
Aligning the Micropilot
An alignment point is to be found on the flange or threaded connection of the Micropilot.
During installation, this should be aligned as follows:
• for tanks: towards the tank wall,
• for stilling wells: towards the slots.
After the Micropilot has been commissioned, the echo quality can be used to determine
the signal strength. If necessary, this can be maximised by optimising the alignment. On
the other hand, optimum alignment using echo quality can also be used minimise the
effect of an interference echo. The advantage here is that a subsequent echo
suppression map will use a lower threshold, causing an overall increase in signal
strength. Proceed as follows:
Warning!
Warning
• Danger of injury when re-aligning the Micropilot. Before the process connection is
unscrewed or loosened, check that the tank is not pressurised and does not contain
substances which are hazardous to health.
1) Empty tank as far as possible.
2) Check whether the distance displayed in V0H8 corresponds to the distance to the
product surface:
– If yes: the echo is a level echo. The echo quality must be maximised.
– If no: the echo is a false echo. The echo quality must be minimised.
3) Unscrew flange or loosen threaded connection by half a turn.
4) Turn flange by one hole or tighten threaded connection by an eighth of a turn. Note
the echo quality.
5) Turn stepwise through 360°, noting the echo quality at each turn.
6) Determine the optimal alignment from the noted echo qualities:
– level echo: maximum value
– interference echo: minimum value.
7) Mount flange or threaded connection in this position.
If necessary renew seal.
8) Record echo suppression map, see Chapter 6.3.

False echo suppression
The factory setting is evaluation mode 0. It is strongly recommended that a customer
echo suppression map is recorded, see Chapter 6.1 and 6.2.
Evaluation mode V3H0
Significance
0: Factory false echo
suppression map
Recorded at the fatory and is active across the entire measuring range.
Suppresses backround noise and matches the antenna to the device.
1: Customer false echo
suppression map
Recorded by the customer, preferably with an empty tank. Serves to suppress
false echoes and to match the Micropilot to the customer's tank.
The customer has three possibilities of suppressing interference echoes.

False echo suppression
When the tank is empty, the distance to the
product surface displayed in V0H8
corresponds to the true level. Echoes are
suppressed up to the proposed distance D
in V3H1.
• D = (V0H8 – 0.8 m)
• Corresponds to Procedure A, Chapter
6.3.
Mode 2
When the tank is empty, the distance to the
product surface displayed in V0H8 does
not correspond to the true level. By
confirming the proposed value in V3H1, the
false echoes are successively suppressed
until the true level is displayed.
• D = (V0H8 + 0.3 m)
• Corresponds to Procedure B,
Chapter 6.3.
Mode 3
The exact distance to the product surface
is known. Echoes up to the distance D
entered in V3H1 are suppressed.

Window suppression
In the case of strong echoes from fittings or welds near to the antenna, all echoes within
a window B below the antenna tip can be suppressed
• The datum point for the window B is the lower face of the process connection.
The factory setting is to the tip of the antenna.
• All echoes within the window B are suppressed.
• Since in certain circumstances the level echo could be suppressed (and there is
no guarantee that no other echo is present), a 10 cm safety zone extends in front
of the window.
• The customer can set the response of the Micropilot to the case where product
enters this zone ("in safety distance").
• The full distance "F" may extend only to the start of the window.

Plausibility
The plausibility check assesses the history of the measured value. It ensures that overspill
cannot happen without a previous alarm or warning. If the signal is lost in close proximity
to the antenna, i.e. in the critical zone where overspill might occur, the last valid measured
value is subject to a plausibility check. This ensures that a false echo from a lower level
cannot be evaluated as the level signal. Micropilot checks every new signal for plausibility
and outputs error E643 in the event of a non-plausible level value.
• The critical zone starts 35 cm below the 100% level (F) and extends to the
antenna tip.
• The plausibility check is automatically activated when one of the application
parameters 4, 5 or 6 is set in V0H3 during calibration. It can also be activated
manually in V8H6.
• Error E643 can be set to act as a warning, alarm or self-holding alarm in V8H5,
see Chapter 6.5.
The plausibility check functions only when a false echo suppression has been performed,
see Chapter 6.1 or 6.2.

Maintenance and Repair
8.1
Maintenance
Check the condition of the transmitter during regular inspections. If necessary, free the
antenna from build-up. When cleaning the antenna, handle with care.
Maintenance
After the exchange of a complete Micropilot or the electronic module, the noted
parameters can be entered (e.g. download from computer) into transmitters with
communication interface or operating and display module. Measurements can then
proceed without the need for calibration.
Exchange
• If necessary, re-activate linearisation in V2H0
• If necessary, record a new echo suppression map, see Chapter 6.3.
A new echo suppression map must be made if the antenna is exchanged.
8.2
Repairs
Should the transmitter need to be repaired by Endress+Hauser, please send it to your
nearest service station with a note containing the following information:
•
•
•
•
An exact description of the application for which it was used
The chemical and physical properties of the product measured
A short description of the fault.
If appropriate the error numbers in V9H0 and V9H1.
Warning!
Special precautions must be observed when sending the transmitters for repair:
• Remove all traces of product.
• This is particularly important if the product can impair health, i.e. is corrosive,
Warning!
poisonous, carcinogenic, radioactive etc..
• If the last traces of dangerous products cannot be removed, e.g. product has
penetrated into fissures or diffused into plastic parts, we kindly ask you not to
send the transmitter for repair.

Spare parts
Installation instructions are packed with the spare part.
Modification nameplate
When spare parts which are part of the product structure (Chapter 9.3/9.4) are ordered,
it must be checked whether the type designation on the nameplate is still valid, e.g. for
•
•
•
•
•
an antenna assembly
an electronic module
an HF module
an operating and display module VU 330
a housing lid with window.
If the type designation changes, a modification nameplate must be purchased. The
specifications of the new transmitter must then be transferred to the modification
nameplate, which must then be fastened to the transmitter. See instructions packed with
nameplate.
In order that the correct nameplate can be delivered, the complete order code must be
specified when a spare housing is ordered, e.g.:
Housing F12/T12
• FMR231E-AAGGJ1A1A
The customer must ensure that the nameplate is correctly filled in.
