Safe Operation and Installation
This section contains important information for effective and safe operation of TKLS fuel level
sensors. Please read the information below before using the sensor.
• Sensors with damaged insulation of conductive parts, testing probe and body must not
be used.
• Operational conditions of the TKLS such as electrical and environmental characteristics
and condition of measured liquid should t the requirements contained in this User Manual.
Otherwise, the manufacturer will not be responsible for sensor safety and functional
efciency.
• All connections should be made when the sensor and external devices to be connected to
the sensor are disconnected from the power supply.

This User Manual applies to the TKLS fuel level sensor (hereafter – TKLS, sensor) produced
by TechnoKom Ltd. It contains installation and connection procedures of the TKLS, as well as
its function and control.
This Manual is intended for specialists who are aware of the maintenance and installation
principles typical for motor vehicles and are procient in using the electronic and electrical
equipment of various vehicles.
To ensure the best performance of the TKLS, it should be installed and set up only by qualied
specialists.
The TKLS sensor can operate both as a part of a fuel monitoring system and as a part of a
eet management system. For proper operation of the TKLS sensor, the customer should be
aware of the operating principles of these systems as a whole, as well as understanding the
functions of its individual components

Product Overview
The TKLS fuel level sensor is designed to measure fuel level in a vehicle fuel tank and transfer
this information to external devices via one of the supported interfaces. The TKLS can be
used as a replacement of the factory-tted standard fuel level sensor or as an additional
sensor for fuel level monitoring.
The TKLS supports data transfer via RS-485 bus, in AGHIP, LLS and Modbus protocols, and
via frequency output as pulses proportional to measured fuel level, PWM signal or periodic
sequence.
In addition to fuel level, the sensor measures ambient temperature and sends the readings
to an external device.
Any device equipped with RS-485 which supports data exchange in AGHIP, LLS or Modbus
protocols can operate as an external device (for example, a level indicator or a eet
management device).
TKLS fuel level sensors support AGHIP protocol which is communication protocol between
AutoGRAPH hardware which enables transmission of additional data, as well as readings of
the sensor built-in inclinometer.
Also connected to AutoGRAPH eet management system, TKLS-L sensor is able to load a
new rmware and new conguration from remote server via GPRS.

1The AGHIP protocol is the AutoGRAPH Hardware Interface Protocol used by AutoGRAPH onboard controllers to communicate with TKLS sensors and
providing exchange of additional information, e.g. inclinometer readings, error reports and etc. In order to establish the communication between the
AutoGRAPH controller and the TKLS sensor in AGHIP protocol, it is sucient to enable the protocol in the controller as it is enabled in theTKLS by default and
does not require any sensor re-conguration. It means that if the device, which theTKLS is connected to, initiates the communication in the AGHIP protocol,
the sensor will automatically recognize it even if other protocol is enabled in the sensor.
2The function is available only for AGHIP and LLS protocols. When theTKLS is connected to the AutoGRAPH on-board controller, the“Wide record”option
should be enabled in the controller’s settings in order the controller to be able to read temperature readings.
