1 Introduction

ApplicationThe Micropilot FMR 231 is a loop-powered transmitter. It is used to for continuous

non-contact level measurement of liquids, pastes and sludges. It is suitable for use in:

•

storage tanks, buffer tanks and stilling wells

with few internal fittings and where the product surface is generally calm. Changes of
product, temperature gradients, inert gas blankets or vapours do not influence the
measurement.

VersionsThe various Micropilot FMR 231 versions result from the combinations between antenna

type, inactive length and the process connection. Table 1.1 summarises them. The
product structure is described in Chapter 9.

1.1 Measurement principle

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 isproportional 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.

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 andprovides a linear outputcurrent for spherical vessels,
horizontal cylinders and tanks with conical outlet.

AccuracyThe 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..

Measuring rangeThe 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.

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.

2.1 Mounting in a tank

General notes

The microwaves should arrive unhindered
at the product surface.

•

Every object within the beam gives an
echo. The nearer the object, the
stronger the echo.

•

Strong echoes which cannot be
avoided by selecting a different
mounting position interfere with the
measurement and must be suppressed
during calibration.

4 Operation

4.1 On-site operation

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
VU 330

The function of the device keys when the operating and display module is not connected
is summarised in the table below. The two keys must always be pressed simultaneously.
The keys are used as follows, see Chapter 5:

Operation with the
VU 330

If the Micropilot is equipped with an operating and display module VU 330, then it is
operated via a 10 x 10 operating matrix.

•

Each row is allocated to a particular function,

•

Each field sets or displays one parameter.

On-site operation with the operating and display module andcommunication both access
the same matrix. This is to be found in Chapter 10. If the HART handheld DXR 275 is
used, the transmitter is operated by a menu which is derived from this matrix.

The table below summarises the key functions of the operating and display module
VU 330.

4.2 Remote operation

The Micropilot can be remotely operated via the communication interface 4...20 mA with
HART.

For HART, the operation depends on the measuring system.

•

For computer operation via Commubox FXA 191 or FXN 672 and gateway, the
operating matrix is used, see page 17.

•

For operation via handheld, a menu is used.

HART handheld DXR 275 The operation of the HART handheld DXR 275 is described in the manual supplied with

it.

The Group Select menu calls the matrix. The rows are the menu headers. Parameters
are set in the roll-down menus.

•

Keys , navigate up and down the menu.

•

Keys , change to the previous or to the following menu.

•

Parameters are entered by the corresponding keys.
– SEND registers the entries

•

Keys F1 - F4 call the displayed functions, e.g. HOME.

In the procedures described in this manual, the DXR 275 menu lines appear in the
"significance" column. Chapter 10 contains a listing ofmenu positions with corresponding
matrix fields.

Note!

•

The HART device description Version 2.0 for Micropilot FMR 231 must be loaded in
the DXR 275 before the device can be operated by the handheld. Updates of the
device descriptions can be obtained from Endress+Hauser.

Graphical support mode The graphical support mode is called via the Device menu. Thus offers an alternative

method of configuring the Micropilot. Various pictures are offered when the Graphics
menu is clicked. These correspond to the procedures described in Chapter 6.

operation.

•

Service: parameters required for service call.

A linearisation can be called from the matrix window.

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.

5 On-site calibration without display VU 330

Test pathAn on-site calibration without the operating and display module VU 330 requiresa 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.

•

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.

Calibration and echo

•

The datum point for the empty distance
"E" and the distance "D" is always the

6.3 Linearisation

Linearisation mode 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.

Warnings 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.

De-activation A linearisation table can be deactivated by setting V2H0 = 0 (m/ft) or 5 (linear). It is not

deleted and can be re-activated at any time by setting V2H0 = 1.

The setting V2H0 = 4 deletes the entire table. The linearisation mode "linear" (V2H5 = 5)
is automatically selected.

Note!

•

The values in V2H5, V0H5 and V0H6 must be changed as necessary.

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.

3: Acknowledges the alarm in case 2..

V8H6 Plausibility

0: off
1: on

The plausibility check is automatically set after the entry of
the application parameter A:

off: application parameters 0 - 3

on: application parameters 4 - 6
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
code E643 is output and the Micropilot reacts according
to the setting in V8H5 – see also Chapter 7.8.

7 Trouble-Shooting

When the instructions in the manual have been followed correctly, the system must now
function. Should this not be the case, the Micropilot provides a number of possibilities
for analysing and correcting faults.

7.1 Self-monitoring

The self-monitoring system differentiates between alarms and warnings.

On an alarm

•

The fault indicator appears at the
operating and display module VU 330.

•

The analogue output responds
according to the settings in V0H7,
V8H3 and V8H5, see table below.

•

The bargraph follows the analogue
output.

An error code is displayed at matrix
position V9H0 to help locate the fault. V9H1
indicates the previous error code.

On a warning

•

The fault indicator appears at the
operating and display module VU 330.

•

The Micropilot continues to measure.

An error code is displayed at matrix
position V9H0 to help locate the fault. V9H1
indicates the previous error code.

Analogue output

The analogue output responds according to the setting in V0H7. If the Micropilot has
been configured with the device keys (no VU 330, DXR 275 or Commuwin II), then the
analogue output goes to MAX (= 22 mA) on a fault.

7.4 Application parameter

Application parameterThe application parameter that is entered during calibration sets the various elements of

the signal evaluation such that the Micropilot is ideally matched to the application.
Parameters are set in both the operating and the service level.

Table 7.3 summarises the parameters available.

HeightThe 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..

First echo factorThe 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.

Tank bottom recognitionThe tank bottom recognition function ensures reliable measurement in the following

cases:

•

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.

7.5 Echo quality

The echo quality of the measurement is displayed in dB in V3H2 and via the bargraph in
V0H8 and V0H9. In this case, each segment represents 5 dB. For devices without
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 byexact 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

•

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.

Warning!

7.6 False echo suppression

Evaluation modeThe 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.

False echo suppressionThe customer has three possibilities of suppressing interference echoes.

Mode 2

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 3

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 4

The exact distance to the product surface
is known. Echoes up to the distance D
entered in V3H1 are suppressed.

7.7 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.

7.8 Plausibility

The plausibility check assesses thehistory 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. Micropilotchecks 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.

7.9 Simulation

Where appropriate, the simulation function allows the linearisation and analogue output
to be tested. The following possibilities exist:

•

Simulation of level: fields V0H0, V0H9 and V9H8 follow the set values.

•

Simulation of volume: fields V0H0, V0H9 and V9H8 follow the set values.

•

Simulation of current: field V9H8 follows the set values.

Depending upon requirement, enter a value in V9H7: Warning E613 appears in V9H0
during simulation.

7.10 Reset

On reset to factory parameters (Code 333), the values in square brackets [] are assumed.
The values in the grey fields are retained.

•

A customer echo suppression map is switched to the factory map: by setting
V3H0 = 1, it can be activated again.

•

A linearisation is set to "linear", but the table values are retained. They are
activated by setting V2H0 = 1. If necessary the values in V2H5 and V0H6 must
be entered again.

8 Maintenance and Repair

8.1 Maintenance

MaintenanceCheck the condition of the transmitter during regular inspections. If necessary, free the

antenna from build-up. When cleaning the antenna, handle with care.

ExchangeAfter 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.

•

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,

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.

Warning!

Micropilot FMR 231 Chapter 8 Maintenance and Repair

Endress+Hauser 45

8.3 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.

Housing F12/T12 In order that the correct nameplate can be delivered, the complete order code must be

specified when a spare housing is ordered, e.g.:

•

FMR231E-AAGGJ1A1A

The customer must ensure that the nameplate is correctly filled in.

Caution!

•

It is not possible to transform a standard device into a device suitable for hazardous
areas by exchanging the parts.

•

For FCC approved devices it is forbidden to make modifications to the device,
unless they are expressly allowed in the operating instructions. A failure to comply
with these instructions could void the user's authority to operate the device.

Caution!
