1. INTRODUCTION
Application
The PiloTREK W–100 non-contact microwave level transmitters provide the
most advanced, new generation measurement technique of the industrial
process automation field. PiloTREK is an ideal solution of high precision
level transmitting of liquids, slurries, dollops, emulsions and other chemicals
in a wide range of application area, such as food industry, energy industry,
pharmaceutical industry, chemical industry, and even in naval applications
with mm accuracy range and high measuring stability.
PiloTREK is able to provide an excellent non-contact measurement solution
for those substances which tend to steam, or for liquids with a gas layer.
Since there is no need for a defined propagation medium in the case of
microwaves, the PiloTREK is applicable in vacuum.
Operation principle
The reflection of the emitted microwave impulses is considerably depending on
the relative dielectric constant of the measured medium. The essential condition
of microwave level measurement is that the relative dielectric constant (εr) of the
medium should be more than 1.9.
The operation of the non-contact microwave level transmitters is based on the
measurement of the time of flight of the reflected signals, so-called Time
Domain Reflectometry (TDR) method.
The propagation speed of microwave impulses is practically the same in air,
gases and in vacuum, independently from the process temperature and
pressure, so the measured distance is not affected by the physical parameters
of medium to be measured.
The PiloTREK level transmitter is a Pulse Burst Radar operating at 25 GHz
(K-band) microwave frequency.
The 25 GHz models’ most noticeable advantage over the lower frequency
(5…12 GHz) radars are the smaller antenna size, the better focusing, lowe
r
dead band and smaller transmission angle.
The level transmitter induces few nanosecond length microwave impulses in the
antenna and a part of the energy of the emitted signals reflects back from the
measurement surface depending on the measured media. The time of flight o
f
the reflected signal is measured and processed by the electronics, and then this
is converted to distance, level or volume proportional data.

3.2.1. DETERMINE THE MAXIMAL MEASURING RANGE
The maximal possible measuring distance of device types: The maximal measuring range of the PiloTREK radars is significantly depending on
the circumstances of the application environment and on the selected device type.
Depending on the relative dielectric constant of the measuring medium and the
process conditions the maximal measurement range (achievable under the
reference conditions) may decrease by even 85% (reduce about to one-sixth!).
In case of planar antenna version, the maximum measuring distance depending on
the dielectric characteristic of the medium to be measured is the same as the
encapsulated DN40 horn antenna version.

with still surface not tending to foaming, vaporing or steaming and in
case of ideally slow (<5 m/h or <16.4 ft/hr) rate of level change.

Depending on the process conditions or the plastic antenna enclosure the following typical reducing factors are recommended to be considered in order to
calculate the maximal measuring range. When more than one reducing factors occur at the same time then all the factors should be considered for the
calculation:
Process Condition Reflection reduction in amplitude Maximum measuring distance decrease by Reducing Factor
Slow mixing or slightly waving 2…6 dB 20…50% 0.8…0.5
Foaming
Fast mixing, vortex 8…10 dB 60…70% (the measurement might be completely terminated) 0.4…0.3
Steaming, condensation 3…10 dB 30…70% (the measurement might be completely terminated) 0.7…0.3
PP antenna enclosure 2 dB 20% 0.8
PTFE antenna enclosure 1 dB 10% 0.9
For example: Measurement medium is Styrene (εr = 2.4) at 25 ºC (77 ºF) process temperature and slowly mixed. The device type is WGS–150–4 with WAT–150–0 antenna
enclosure. The maximal measuring range is (9 m [29.5 ft] * 0.5 * 0.9) = 4 m (13 ft).

3.3. ACCESSORIES
User’s and Programming Manual
Warrant Card
EU declaration of Conformity
2× M20x1.5 cable glands
Sealing (Klinger®Oilit) only for BSP threaded process connection
3.4. CONDITIONS OF SAFE OPERATION
To avoid the danger of electrostatic charge accumulation, in case of the WP, WMtypes (with plastic electronic housing, plastic antenna enclosure or PP
flange) the following safety rule shall be observed:
The measured medium should be an electrostatic conductor, and the electrical resistivity of the measured medium cannot exceed 104.
The speed and the method of the filling and emptying process should be chosen properly according to the measured medium.
The material of the plastic antenna enclosures can produce static electricity. The antenna enclosure is allowed to clean only with wet rag.
The wiring chamber cover of the Ex d [ia] dual compartment flameproof housing may not be opened while the electrical circuits are energized or if
explosive atmosphere is present.
If the WS with aluminum housing is installed into a location which requires ‘Ga’ protection level, the units should be mounted that they are protected against
rare occurring impacts and friction effects which may be source of a potential ignition.
Meeting the requirements of the technological process
Please carefully consider that all parts of the instrument which possible to come into contact with the measured medium – including the transducer, the sealing
and any other mechanical parts – should meet all requirements of the applied technological process, such as the process pressure, temperature and chemical
effects of the used technologies. In addition, it is necessary to take into account at devices with PP flange that the PP flange’s mechanical strength is much
smaller than the same sized metal flanges.
FCC Radio license
This device complies with Part 15 of the FCC Rules. 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. Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.
3.5. REPAIR,MAINTENANCE AND STORAGE CONDITIONS
PiloTREK units do not require maintenance on a regular basis. Repair during or after the guarantee period should only be carried out by NIVELCO.
Before returning the device for repairs, it must be cleaned carefully, the parts in contact with the medium that might contain harmful substances must be
decontaminated. Our official form (Returned Equipment Handling Form) must be enclosed. Download it from our website www.nivelco.com. The device must be
sent with a declaration of decontamination. Please provide a statement in the declaration that the decontamination process is completed, the device is clean and
free from harmful materials, and there are no hazardous substances on it.
Unused devices must be stored within the ambient temperature range specified in the technical data, and a maximum of 98% relative humidity.

4. INSTALLATION
4.1. MOUNTING
When choosing the installation place please ensure proper space for later calibrations, verification or maintenance service.
PLACEMENT
The ideal position for the PiloTREK is on their = (0.3…0.5) R (in case of
cylindrical tank).
It is highly recommended to consider the beam cone on the 2nd page drawing.
The distance between the sensor and the tank wall should be at least
200 mm (7.9 inch). If the unit is installed into dome top or spherical tank,
unwanted multiple reflections may appear, which can cancel each other and the
measuring signal out, this way it can interfere the measurement.
r
R
MOVING LIQUID SURFACE
Waving, vortex or strong vibration effects can have negative influence on the
measurement accuracy and the maximal measuring range. To avoid these
effects, the mounting placement should be as far as possible from the sources of
these disturbing effects. According to measurement experiences the maximal
measuring distance may decrease by 50…70% when the liquid surface is
vortexing (see chapter 3.2). For this reason, the device should be mounted as far
as possible from the filling stream or the tank outlet.
FOAMING
Filling, stirring or any other processes in the tank can
generate dense foams on the liquid surface, which may
considerably damp the reflected signals.
According to measurement experiences, in these cases
the maximal measuring distance decreases at least
approximately by 50%.
FUMES, VAPOURS
If the measured medium or its foam can reach the
antenna or the measured medium is highly
fuming, these cases build-ups can form on the
sensor, which may result unreliable level
measurement.
