Model SI-7000 LTD Tank Gauging System

All New For 2016!

We proudly introduce – after 40 years of delivering the world's most trusted LNG tank-top LTD systems – the completely reimagined, redesigned, and most advanced solution for LNG tank profiling: The Scientific Instruments Model SI-7000 LTD. Some of the key features include:

  • Level, temperature, and density sensing in a single probe
  • All-stainless construction for superior corrosion resistance in extreme environmental conditions
  • Robust chain drive
  • Stilling well not required
  • Symmetrically balanced for flange mounting and support
  • Accurate liquid level measurement with discrete dual sensor level detection array and smart feedback
  • Advanced, self-calibrating electronics with embedded high resolution, full color, touch-screen HMI
  • Safe and simple access to internal components for ease of maintenance
