Measuring principle
The Micropilot is a "downward-looking" measuring system, operating based on the time-of-flight
method (ToF). It measures the distance from the reference point R to the product surface. Radar
impulses are emitted by an antenna, reflected off the product surface and received again by the radar
system.

1 Setup parameters of the Micropilot

F Full calibration (= span)
D Measured distance
L Level (L = E - D)
Q Flow rate at measuring weirs or channels (calculated from the level using linearization)
R Reference point
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. This clear signal detection system benefits from over 30 years'
experience with time-of-flight procedures.
The distance D to the product surface is proportional to the time of flight t of the impulse:
D = c · t/2,
where c is the speed of light.
Based on the known empty distance E, the level L is calculated:
L = E – D
Output The Micropilot is adjusted by entering the empty distance E (= zero point) and the full distance F (=
span).
• Current output: 4 to 20 mA
• Digital output (HART, SmartBlue): 0 to 10 m (0 to 33 ft) or 0 to 20 m (0 to 66 ft) depending on
antenna version

Input
Measured variable The measured variable is the distance between the reference point and the product surface.
The level is calculated based on E, the empty distance entered.
Measuring range Maximum measuring range
Device Maximum measuring range
FMR20 with 40 mm (1.5 in) antenna 10 m (33 ft)
FMR20 with80 mm (3 in) antenna 20 m (66 ft)
Requirements of the installation

The following table describes the media groups.
Media groups
εrExample
4 to 10 E.g. concentrated acid, organic solvents, ester, aniline, alcohol, acetone.

The measurements are carried out in accordance with EN 61298-3.
• Digital (HART, Bluetooth® wireless technology):
Standard version: average TK = ± 3 mm (0.12 in)/10 K
• Analog (current output):
– Zero point (4 mA): average TK = 0.02 %/10 K
– Span (20 mA): average TK = 0.05 %/10 K

Caution!
• The sensor cables are not designed as supporting cables. Do not use as a suspension wire.
• In the free-field, a vertically downward orientation must be ensured at all times
Nozzle installation
The antenna should be just out of the nozzle for optimum measurement. The interior of the nozzle
must be smooth and may not contain any edges or welded joints. The edge of the nozzle should be
rounded if possible. The maximum nozzle length L depends on the nozzle diameter D. Please note

11 Tank installation position
• If possible install the sensor so that its lower edge projects into the vessel.
• Recommended distance A wall - nozzle outer edge: ~ 1/6 of the tank diameter D. However, the
device must not under any circumstances be mounted closer than 15 cm (5.91 in) to the tank wall.
• Do not mount the sensor in the center of the tank.
• Avoid measurements through the filling curtain.
• Avoid equipment such as limit switches, temperature sensors, baffles, heating coils etc.
• Several devices can be operated in a single tank without impacting on each other.
• No signals are analyzed within the Blocking distance (BD). It can therefore be used to suppress
interference signals (e.g. the effects of condensate) close to the antenna.
An automatic Blocking distance of at least 0.1 m (0.33 ft) is configured as factory setting.
However, this can be overwritten manually (0 m (0 ft) is also permitted).
Automatic calculation:
Blocking distance = Empty calibration - Full calibration - 0.2 m (0.656 ft).
Each time a new entry is made in the Empty calibration parameter orFull calibration parameter,
the Blocking distance parameter is recalculated automatically using this formula.
If the result of the calculation is a value <0.1 m (0.33 ft), the Blocking distance of0.1 m (0.33 ft)
continues to be used.

Measurement in plastic vessels
If the outer wall of the vessel is made of a non-conductive material (e.g. GFR) microwaves can also be
reflected off interfering installations outside of the vessel (e.g. metallic pipes (1), ladders (2),
grates (3), ...). Therefore there should be no such interfering installations in the signal beam. For
more information, please contact Endress+Hauser.

Pressure equipment with
allowable pressure
≤ 200 bar (2 900 psi)
Pressure instruments with a flange and threaded boss that do not have a pressurized housing do not
fall within the scope of the Pressure Equipment Directive, irrespective of the maximum allowable
pressure.
Reasons:
According to Article 2, point 5 of EU Directive 2014/68/EU, pressure accessories are defined as
"devices with an operational function and having pressure-bearing housings".
If a pressure instrument does not have a pressure-bearing housing (no identifiable pressure chamber
of its own), there is no pressure accessory present within the meaning of the Directive.

countries of the EU and EFTA. that have implemented this standard.
The following countries are those that have currently implemented the directive:
Belgium, Bulgaria, Germany, Denmark, Estonia, France, Greece, UK, Ireland, Iceland, Italy,
Liechtenstein, Lithuania, Latvia, Malta, The Netherlands, Norway, Austria, Poland, Portugal,
Romania, Sweden, Switzerland, Slovakia, Spain, Czech Republic and Cyprus.
Implementation is still underway in all of the countries not listed.
Please note the following for operation of the devices outside of closed vessels:
1. The device must be mounted in accordance with the instructions in the "Installation" section.
2. Installation must be carried out by properly trained, expert staff.
3. The device antenna must be installed in a fixed location pointing vertically downwards.
4. The installation site must be located at a distance of 4 km from the astronomy stations listed
below or otherwise approval must be provided by the relevant authority. If the device is
installed at a distance of 4 to 40 km from one of the listed stations, it must not be installed at a
height of more than 15 m (49 ft) above the ground.

FCC / Industry Canada This device complies with Part 15 of the FCC Rules [and with Industry Canada licence-exempt RSS
standard(s)]. Operation is subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts
de licence. L'exploitation est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire
de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si
le brouillage est susceptible d'en compromettre le fonctionnement.
[Any] Changes or modifications made to this equipment not expressly approved by Endress+Hauser
may void the FCC authorization to operate this equipment.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected
• Consult the dealer or an experienced radio/TV technician for help
• The installation of the LPR/TLPR device shall be done by trained installers, in strict
compliance with the manufacturer’s instructions.
• The use of this device is on a “no-interference, no-protection” basis. That is, the user shall
accept operations of high-powered radar in the same frequency band which may interfere
with or damage this device. However, devices found to interfere with primary licensing
operations will be required to be removed at the user’s expense.
• Only for usage without the accessory “flooding protection tube”, i.e. NOT in the free-field:
This device shall be installed and operated in a completely enclosed container to prevent RF
emissions, which can otherwise interfere with aeronautical navigation.
