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 (process connection) to the product
surface. Radar impulses are emitted by an antenna, reflected off the product surface and received
again by the radar system.

E Empty calibration (= zero)

D Measured distance
L Level (L = E - D)
Q Flow rate at measuring weirs or channels (calculated from the level using linearization)
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)
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

Requirements of the installation
• Tank height greater than 1.5 m (5 ft)

• 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.
Media groups
εrExample
4 to 10 E.g. concentrated acid, organic solvents, ester, aniline, alcohol, acetone.
> 10 Conductive liquids, aqueous solutions, diluted acids and bases
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
Operating frequency K-band (~ 26 GHz)
Transmission power Distance Mean power density in the direction of the beam
1 m (3.3 ft) < 12 nW/cm2
5 m (16 ft) < 0.4 nW/cm2

Output
Output signal 4 to 20 mA
A 4 to 20 mA interface serves as measured value output and to power 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 at least 10 m (33 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 Depending on the interface, failure information is displayed as follows:
• Current output
Alarm current: 22.5 mA
• SmartBlue (app)
– Status signal (as per NAMUR Recommendation NE 107)
– Plain text display with remedial action
Linearization The linearization function of the device allows the conversion of the measured value into any unit of
length, weight, flow or volume.
When operating using SmartBlue (app), up to 32 value pairs can be entered manually into the table.
