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
E Empty calibration (= zero)
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 (SmartBlue): 0 to 5 m (0 to 16 ft) or 0 to 8 m (0 to 26.25 ft) in combination with
accessory "flooding protection tube"

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
FMR10 5 m (16 ft)
FMR10 with accessory "flooding protection tube" 8 m (26.25 ft)
Requirements of the installation
• Tank height > 1.5 m (5 ft)
• Open channel minimum width 0.5 m (1.6 ft)
• Calm surfaces
• No agitators
• No buildup
• Relative dielectric constant εr > 4
Usable measuring range
The usable measuring range depends on the antenna size, the medium's reflective properties, the
installation position and any possible interference reflections.
The following table describes the media groups.

Example
Reduction of the max. possible measuring range by:
• Media with bad reflective properties (= low εr value)
• Formation of buildup, particularly of moist products
• Strong condensation
• Foam generation
• Freezing of sensor

Output
Output signal 4 to 20 mA
An 4 to 20 mA interface is used for measured value output and to power to the device.
Digital output Bluetooth® wireless technology
The device has a Bluetooth® wireless technology interface and can be operated and configured via
this interface using the SmartBlue app.
• The range under reference conditions is 25 m (82 ft)
• Incorrect operation by unauthorized persons is prevented by means of encrypted communication
and password encryption.
• The Bluetooth® wireless technology interface can be deactivated.
Signal on alarm
Linearization
Depending on the interface, failure information is displayed as follows:
• Current output
Alarm current: 22.5 mA (as per NAMUR RecommendationNE 43)
• SmartBlue (app)
– Status signal (as per NAMUR Recommendation NE 107)
– Plain text display with remedial action
The linearization function of the device allows the conversion of the measured value into any unit of
length, weight, flow or volume.
When operating via SmartBlue (app), up to 32 value pairs can be entered manually into the
linearization table.
