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-fitted 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 fleet
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 fleet management system, TKLS-L sensor is able to load a
new firmware and new configuration from remote server via GPRS.
