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 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.
The points "E" and "F" correspond to 0% and 100% level for both the digital output and
the display.

LinearisationA 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.
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 or ±0.1% of the range end-value, which ever is
greater.
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.

A* Non-conducting liquids, e.g. propane, buthane etc.
Dielectric constant εr. 1.4...1.9
B Non-conducting liquids, e.g. petrochemicals, benzine, oil, toluol, etc.

3 Connection
General notes Micropilot is a loop-powered transmitter with PROFIBUS-PA output. The segment coupler
supplies the power. Note the following before connecting up:
•Turn off the power before connecting up.
•Connect the external ground terminal of the transmitter to the plant grounding
system before connecting up.
•Check that the locking screw on the housing is tight: it makes the connection
between the antenna and the housing ground potential.
Hazardous areas 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. For certified transmitters, the explosion protection is realised
as follows:
•Housing F12: EEx ia.
The power from the segment coupler must be intrinsically safe.
•Points to note when installing are to be found in the XA-instructions supplied with
the device
•The electronics are galvanically isolated from the antenna circuit.
Cable Twisted, shielded pairs must be used. The cable specifications can be taken from
TI 260F/BA 198F or the certificate. The following have been found suitable:
•Non-hazardous applications: Siemens 6XV1 830-5BH10, Belden 3076F,
Kerpen CEL-PE/OSCR/PVC/FRLA FB-02YS(ST)YFL.
•Hazardous areas Siemens 6XV1 830-5AH10.
Screening High integrity potential bonding must be provided between the housing and the cable
screening.
•The external ground terminal on the transmitter must be connected to ground.
•The continuity of the PA cable screening between tapping points must be
ensured.
•The screening must be grounded at each end of the cable.
•If there are large differences in potential between grounding points, the
grounding should run via a capicitor that is suitable for high frequency use
(e.g. ceramic 10 nF/250 V~).

4.2 Setting the device address
Every PROFIBUS-PA device must be given an address. If the address is not set correctly,
the device will not be recognised by the process control system. Addresses between 0
and 126 are valid. A device address may appear only once within a particular PROFIBUS-
PA network. All devices are supplied ex-works with the address 126. This address can
be used to check the function of the device and to connect it into an operating
PROFIBUS-PA network. Afterwards, the address must be changed to allow other devices
to be connected to the network.
There are two possibilities to set the address of the Micropilot FMR 231: remotely by using
an operating program (PROFIBUS-DP Master Class 2, e.g. Commuwin II), or locally at
the DIP-switches. The latter are to be found behind the operating and display module in
the display compartment.
Setting the address
mode
Switch No. 8: ON = addressing via the bus system
OFF = addressing at the device via DIP switches 1 to 7.
The value of the switches is as follows:
A change in the switch settings first becomes effective on the next powering up of the
device.

4.3 Device data base and type files
The device data base file (GSD) is required when planning a PROFIBUS-DP network.
The file (a simple text file) contains information on the data transmission rates supported
by the device as well as the digital information and formats the device provides when
communicating with the programmable logic controller.
Every device is allocated an identity code by the PROFIBUS User Organisation (PNO).
This appears in the device data base file name (.gsd). For Endress+Hauser devices, the
identity code is always 15xx, where xx is device dependent.
The full set of device data base files for Endress+Hauser devices can be obtained as
follows:

PNO →
http://www.profibus.com (GSD library)
•As diskette direct from Endress+Hauser: Order No. 943157-0000
The device data base file set contains the following:
•All Endress+Hauser gsd files
•Endress+Hauser type files
•Endress+Hauser bitmap files
•Addition information on the devices.
Working with the .gsd
and type files The .gsd files must be loaded into a specific subdirectory in the planning software of your
PLC.
Example 1 In the case of the Siemens STEP7 planning software for the Siemens PLC S7-300/400,
the files must be loaded into the subdirectory \siemens\step7\s7data\gsd. For other
planning software or PLCs, consult the manual or ask the manufacturer for the correct
subdirectory.
The bitmap files also belong to the .gsd files. These allow the measuring point to be
represented by an icon. For the STEP7 software, the bitmap files must be loaded into the
subdirectory \siemens\step7\s7data\nsbmp.
Example 2 If the PLC is a Siemens S5 and the planning software for the PROFIBUS-PA network is
COM ET200, then the type files are required (extension .200).
Example 3 The GSD directory has a subdirectory containing GSD files with the non-standard
identifier (0x94). These are for use e.g. with the Allen-Bradley PLC5.
