Sensors
General Information
This User Manual is designed for Omnicomm LLS 30160 and Omnicomm LLS-AF 4 fuel level
sensors.
Omnicomm LLS 30160 is a fuel level sensor with RS-232 and RS-485 interfaces.
Omnicomm LLS-AF 4 is a fuel level sensor with analog and frequency interfaces.
While carrying out installation, observe the safety rules and regulatory requirements for this
type of work.
Minimum allowable length of the measuring piece is 150 mm.
The dielectric permeability of the measured medium should be constant. Failure to comply
with this requirement will lead to increased measurement error.

Preparation
Fuel Tank Preparation
1. Select the location for Omnicomm LLS sensor installation, taking into account the
following requirements:
The installation location should be as close to the geometric center as possible and be
placed at the deepest level of the tank:
When installed, the sensor should not be in contact with reinforcement ribs and existing
equipment inside the tank
Installing two sensors in one fuel tank allows to significantly reduce the de-pendence of
the fuel level on the vehicle inclination angle:

2. Steam out the tank to comply with safety regulations
3. Drill out the central bore using a bimetal core drill (or hole saw) ø35 mm
4. Drill out four mounting holes according to the diagram:
The mounting hole diameter depends on the material of the tank:
ø 4 mm – for metal tanks with wall thickness over 3 mm (cut M5 thread)
ø 7 mm – for plastic and metal tanks with wall thickness up to 3 mm (for rivets)
ø 4 mm – for plastic tanks with wall thickness over 3 mm
Preparation

Sensor Preparation
1. Measure the depth of the tank. Cut the sensor measuring piece so that its length is
20mm less than the depth of the tank. Ensure that the shearing line is perpendicular to
the sensor's longitudinal axis
2. Use oil-and-petrol resistant non-conductive sealant to fill the insulation cap (included in
the kit) to 1/4–1/5 of its volume. Recommended sealants: PERMATEX™ MotoSeal® Black,
ABRO™ Black, ABRO™ Red
3. Put the insulation cap on the central rod of the Omnicomm LLS sensor

In the tab “Settings” under “Custom parameters”:
“Network address” (1 to 254) – set the network address for the Omnicomm LLS fuel level
sensor. When several sensors are connected to one external device, they should have
unique network addresses.
“Maximum reading” (1 to 4095) – select the maximum reading for the LLS fuel level
sensor. Default value – 4095.
“Minimum reading” (0 to 1023) – select the minimum reading for the LLS fuel level sen-
sor. Default value – 0.
“Filtration” – set the output signal filtration parameters as follows:
“None”– no filtration is performed. This option is used, when the filtration is carried out
by an external device.
“Minimum”– this filtration is used in stationary fuel storages and non-mobile machinery
“Medium”– this filtration is used when the vehicle operates in normal road conditions
“Maximum”– this filtration is used when the vehicle operates in severe road conditions
“Automatic data output”– select:
“No output” – no automatic data output (without request) is performed
“Binary” – automatic binary data output
“Character” – automatic character data output
“Data output interval” (1 to 255 seconds) – set the automatic data output interval
The automatic data output mode may be used with no more than one
Omnicomm LLS 30160 sensor connected to one interface.

“Max. frequency value (100 to 2000) Hz” - set the maximum frequency value. Between
100 and 1053 Hz, when connecting to Omnicomm terminals. Default value – 2000 Hz.
“Min. frequency value (30 to 1900) Hz” - set the minimum frequency value. Default value
– 30 Hz.
“Pull-up resistor”. Select “On” if, according to the manufacturer's instructions, the voltage
signal is connected to the input of an external device. Select “Off” if the type of the
connected signal is “dry contact” or “transistor NPN key”.
Installation and Connection
1. Put the mounting point gasket (included in the kit) on the Omnicomm LLS sensor
measuring probe
2. Put the Omnicomm LLS sensor into the tank and secure it:
when securing with rivets, use a rivet gun (riveter)
when securing with bolts, first put a seal (one on each bolt), a spacer and a spring wash-
er
when securing onto a plastic tank with wall thickness of more than 3 mm, use the self-
tapping screws and a seal (one on each self-tapping screw), included in the kit
3. Connect the Omnicomm LLS sensors to an external device as shown in the diagram:

Calibration
Calibration of the fuel tank is necessary to verify the conformity of the digital code issued by
the Omnicomm LLS 4 sensor to the fuel volume in a particular fuel tank.
Calibration of the fuel tank is performed by filling up the tank – from empty to full, with a
certain filling interval, and recording the Omnicomm LLS sensor readings in the calibration
table.
A container may be calibrated by draining.
The calibration of a container with multiple Omnicomm LLS 30160 sensors is performed
similarly to the calibration with one sensor. Before the calibration process, add the neces-
sary quantity of sensors and specify the network addresses. Calibration is performed for all
sensors at the same time. Connect multiple sensors to a PC or tablet using a KTZ splitter.
Calibration of the tank with one Omnicomm LLS sensor:
1. Empty the fuel tank
2. Connect the sensor to a PC or tablet according to the diagram in the Setting section.
3. Run the Omnicomm Configurator program on your PC or tablet. Select “Tank calibration”

connected Omnicomm LLS sensors, select “Refresh the list of devices” in the menu.
4. Set the flow interval in liters
Perform filling using a measuring container or under control of a fluid flowmeter with a
predefined interval. The container must have a metrological calibration test certificate.
5. Press the “Start/continue calibration” button
6. Fill with an amount of fuel equal to the flow interval
7. Press “Add line”
The “Liters” column will display the filling volume equal to the predefined flow interval.
The “Sensor” column will display the value equal to the filling volume.
8. Press “Add line”
9. Repeat items 6, 7 and 8 according to the number of control
10. Press the “Finish calibration” button
11. Save the calibration table in the calibration file (.ctb), Omnicomm Online (.xml) file, in
the Terminal or Indicator, by pressing the “Export” button
When performing the calibration table export to the Omnicomm Online (.xml) file, the “Ex-
port” window will open. Specify the Omnicomm LLS sensor number to display in
Omnicomm Online.
The calibration of a container with multiple LLS-AF sensors is performed separately for each
sensor. To import a vehicle profile with multiple LLS-AF calibration tables into Omni-comm
Online:
1. Perform the calibration process for each LLS-AF sensor
