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

R Reference point
Input The reflected radar pulses are received by the antenna and transmitted to the electronics. A
microprocessor evaluates the signals and identifies the level echo caused by the reflection of the
radar pulses 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 pulse:
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 calibrated 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 8 m (0 to 26.25 ft) or 0 to 12 m (0 to 39.37 ft) in connection with
mounted "flooding protection tube" accessory.

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 with 40 mm (1.5 in) antenna: 8 m (26.25 ft)
• Device with 40 mm (1.5 in) antenna and with mounted "flooding protection tube" accessory:
12 m (39.37 ft)
Installation requirements
• 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
Contact Endress+Hauser for lower εr values
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.
Media groups
• εr = 4 to 10
e.g. concentrated acid, organic solvents, ester, aniline, alcohol, acetone.
• εr > 10
e.g. conductive liquids, aqueous solutions, diluted acids and bases
Reduction of the maximum 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 Mean power density in the direction of the beam
• At a distance of 1 m (3.3 ft): < 12 nW/cm2
• At a distance of 5 m (16 ft): < 0.4 nW/cm2
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

length, weight, flow or volume.
When operating via SmartBlue (app), up to 32 value pairs can be entered manually into the
linearization table.

• The sensor cables are not designed as supporting cables. Do not use them for suspension
purposes.
• Always operate the device in a vertical position in free-space applications.

must be smooth and may not contain any edges or welded joints. The edge of the nozzle should be
rounded if possible.

 8 Installation position on a vessel
• 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 vessel diameter D. Under no
circumstances should the device be mounted closer than 15 cm (5.91 in) to the vessel wall.
• Do not install the sensor in the middle of the vessel.
• Avoid measurements through the filling curtain.
• Avoid equipment such as limit switches, temperature sensors, baffles, heating coils etc.
• No signals are evaluated within the Blocking distance (BD). It can therefore be used to suppress
interference signals (e.g. the effects of condensate) in the vicinity of the antenna.
An automatic Blocking distance of at least 0.1 m (0.33 ft) is configured as standard. 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 or Full 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 of 0.1 m (0.33 ft)
will continue to be used.
Device alignment for installation on a vessel
• Align the antenna vertically to the product surface.
• Align the eyelet with lug towards the vessel wall as well as possible.

If the outer wall of the vessel is made of a non-conductive material (e.g. GFR), microwaves can also
be reflected by interfering installations outside of the vessel.
Please ensure there are no interfering installations made of a conductive material in the signal beam
(see the beam angle section for information on calculating the beamwidth diameter).
Please contact the manufacturer for further information.

For outdoor use, a weather protection cover is recommended.

Use of flooding protection tube
The flooding protection tube ensures the sensor measures the maximum level even if it is completely
flooded.
In free-field installations and/or in applications where there is a risk of flooding, the flooding
protection tube must be used.
The flooding protection tube can be ordered as an accessory or together with the device via the
product structure "Accessory enclosed".

The tube is screwed directly onto the sensor and seals off the system by means of an O-ring making
it air-tight. In the event of flooding, the air pocket that forms in the tube ensures the measurement
of the maximum level at the end of the tube. Due to the fact that the Blocking distance is inside the
tube, multiple echoes are not analyzed.
