LRC Small System is a complete radio controlled fill- and overfill prevention system for tanker trucks and many other applications. It is designed for the filling / refilling of tanks and tanker trucks as well as for ship bunkering and other applications.

For ship-bunkering in european inland waterways overfill-prevention systems are obligatory by law. This is for example for Netherland ships an optical limit sensor, for German and other ships an electronical limit probe according to EN13616, for other ships a floating probe.
All 3 systems can be covered with the LRC-Small Ship.


The following functions can be realized with LRC Small:

  • Motor (Pump) Start/Stop
  • Filling Start/Stop
  • Rotational Speed Control
  • Fill interruption/Restart
  • Hose Reel Control
  • Dead-Man Control
  • ANA (Germany)
  • Automatic fill-stop

The following limit probes can be controlled:

  • Limit probes according to TRbF (PTC thermistor probes – meeting EN13616)
  • Floating probes (nose 10h)
  • Optical probes (Switzerland Standard and Ships Standard BeNeLux)
  • Probes with relais contacts

Using LRC Small in combination with an overfill probe, overfill is avoided with 100% safety.
LRC Small is approved for use in hazardous areas, EX-areas and non-EX areas as well.
Many years of experiences have made this system to an important part of the equipment for  ship bunkering systems.
