ISA 100 WirelessRemote leak detection for pipe line was needed to meet new environmental statute. However cabling earthwork is strictly restricted to protect land environment.

onshore pipe line


  • Improved safety by monitoring oil leak.
  • Reduced environmental burden by avoiding land pollution
  • Improved company image to be law abiding.


  • Strictly limited earthwork based on regulation.
  • Long distance communication up to 2 km without repeater.


Introduction of wireless pressure transmitters and temperature trasmitters.

Built large scale star network using high gain antenna based on Yokogawa plant-wide field wireless system.
