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.

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.

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

 7 Tank installation position
• If possible install the sensor so that its lower edge projects into the vessel.
• Do not install the sensor in the middle of the tank (2). We recommend leaving a distance (1)
between the sensor and the tank wall measuring 1/6 of the tank diameter.
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.
• Avoid measurements through the filling curtain (3).
• Avoid equipment (4) such as limit switches, temperature sensors, baffles, heating coils etc.
• Multiple devices can be operated in one tank without influencing each other.
• No signals are analyzed within the Blocking distance. It can therefore be used to suppress
interference signals (e.g. the effects of condensate) close to the antenna.
By default an automatic Blocking distance of at least 0.1 m (0.33 ft) is preset. However it can be
manually overwritten (even 0 m (0 ft) is allowed.
Automatic calculation:
Blocking distance = Empty calibration - Full calibration - 0.2 m (0.656 ft).
The Blocking distance parameter is recalculated according to this formula every time a new value
is entered into the Empty calibration parameter or Full calibration parameter.
If this calculation results in a value <0.1 m (0.33 ft), the blocking distance of 0.1 m (0.33 ft) is
used instead.
Alignment
• Align the antenna vertically to the product surface.
• Align the eyelet with the mounting eye as well as possible towards the tank wall.

 9 Relationship between beam angle α, distance D and beamwidth diameter W
The beam angle is defined as the angle α at which the power density of the radar waves reaches half
the value of the maximum power density (3dB width). Microwaves are also emitted outside the
signal beam and can be reflected off interfering installations.

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.

Cleaning the antenna The antenna may become contaminated depending on the application. Emission and reception of
microwaves can thus be hindered. The level of contamination leading to an error depends firstly on
the medium and secondly on the reflectivity, mainly determined by the dielectric constant εr.
If the medium tends to cause contamination and buildup, cleaning on a regular basis is
recommended. Care must be taken to ensure the antenna is not damaged in the process of
mechanical or hose-down cleaning. Material compatibility must be taken into account if cleaning
agents are used! The maximum permitted temperatures must not be exceeded.
