The high-frequency level sensor RFLS–35 is designed for industrial use for limit sensing of the
level of liguid and paste-like media. The high-frequency level sensor may be a direct replacement of
a vibrating level sensor, or of a capacity level sensor in case of more demanding applications. The
media may be electrically conductive or non-conductive with any permittivity. It can be installed in
metalorplastictanks,pipes,llingtanks,sumps,etc.
It is mainly designed for mounting into the wall of a tank or pipe, in which the actual detection of the
level will take place. The sensor works in the high frequency band, enabling reliable detection of
the level of media, and eliminating deposits or foam on the electrode. The sensor suppresses the
inuenceofdepositsofviscousmedia(ketchup,yoghurt,pastes,syrups,jamsandjellies,creams,
soap)aswellaselectricallyconductiveadhesiveproducts(detergents,alkalis,chemicals).

The sensor is made from a stainless steel housing at one end terminated by a sensing electrode,
and terminated at the other and by an ending with a status indicator, control elements and electrical
connection.

RFLS level sensors can be mounted in horizontal or inclined position into the shell of a con-
tainer, storage tank or pipe by screwing into the welding ange, or by axing using a nut.
Basic application recommendations are mentioned below.
During assembly into the metal tank or the storage tank, it is not necessary to separately ground
the base of the level sensor
Inthecaseoftheuse for an aggressive medium isnecessary to provethe chemical compatibility
of used materials of the sensor (Tab. Used materials on page 19). This guarantee ceases when
the product is chemically damaged.
Thanks to its design, the sensor is appropriate for detection of the level of viscous and simultane-
ously electrically conductive media (yoghurt,jamsandjellies,mayonnaise,spreads,liquidsoap,
creams or pastes). After setting the sensitivity of the given media, it reliably reacts to the presence
or absence of a medium level. On the contrary, the sensor does not react to remnants and coatings
of viscous media on the measuring electrode.

sensors in a horizontal pipe

or adhering remnants
of liquid at the bottom
of the pipe.
Upon vertical installation of the
sensor in a pipe, pay attention to
potential formation of air pockets,

Electrical connection can only be made when de-energized!
The source of the power voltage must comprise of a stabilised safe low power source with
galvanic separation. In the event that a switch-mode power supply is used, it is essential that
its construction effectively suppresses common mode interference on the secondary side. In
the event that the switch-mode power supply is equipped with a PE safety terminal, it must
be unconditionally grounded! Spark-safe devices type (RFLS–35Xi and RFLS-35XiM) must
be powered from a spark-safe power source meeting the above-mentioned requirements.
In the event that the level meater (sensor) is installed in an outdoor environment at a distance
greater than 20 m from the outdoor switchboard, or from an enclosed building, it is necessary
to supplement the electrical cable leading to the level meater (sensor) with suitable overvoltage
protection.
With regard to possible occurrence of electrostatic charge on non-conductive parts of the
sensor for explosive areas (RFLS–35Xi and RFLS–35XiM, sensors must be grounded. It will be
done using conductive tank, conductive lid of tank, or by the auxiliary plate electrode PDE-27.
In the event of strong ambient electromagnetic interference, paralleling of conductors with
power distribution, or for distribution to distances over 30 m, we recommend grounding the
level meter (see above) and using a shielded cable.

BASIC SETTINGS
For setting the sensitivity and switching mode, where it is possible to submerge the sensor in or
remove it from the medium. When using this setting, the sensor eliminates the presence of deposits
and foam on the electrode.
1. Bring the level of the measured medium in the tank to a state so that the sensor electrode would
be covered.
2. Place the magnetic pen for at least 2 seconds** on the sensitive spot ofthesensor(until
both LEDs illuminate) and then remove the magnetic pen. Settings are conrmed by three
ashesoftheorangeLED.
3. Bring the level of the measured medium in the tank to a state so that the sensor electrode would
be uncovered. Leave possible deposits on the electrode.
4. Place the magnetic pen for at least 2 seconds** on the sensitive spot of the sensor un-
tilbothLEDsilluminateandthenremovethemagneticpen.Settingsareconrmedbythree

For safety reasons, we recommend setting the mode “O” for level sensing (the sensor is closed
upon immersion). It is for failure safety reasons – eventual failure of sensor behaves similarly as
an exceeding of the limit state. Analogically, for the maximum level it is recommended to set the
mode “C” (the sensor is open upon immersion).
