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:
Preparation

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
