TKLS: SPECIFICATIONS

SHORT DESCRIPTION

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 LLS and Modbus protocols, and via frequency output as pulses proportional to measured fuel level.

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 LLS or Modbus protocols can operate as an external device (for example, a level indicator or an onboard vehicle tracking device).
