After 50 years of delivering the world's most trusted LNG tank-top LTD systems – the completely re-imagined, redesigned, and most advanced solution for LNG tank profiling: The Scientific Instruments Model SI-7000 LTD. The SI-7000 Probe has dedicated sensors for level, temperature and density of LNG measurements, all embedded into a robust stainless steel housing.
Scientific Instruments Model SI-7000 LTD Tank Gauging System
The SI-7000 LTD is the most dependable solution for level, temperature, and density profiling in LNG & LPG Storage Tanks. The SI-7000, a third generation LTD from Scientific Instruments was designed to meet today’s demanding safety regulations. Now on smaller footprint, built-in intuitive keypad display, optimized performance, reliability and accuracy. The SI-7000 Probe has dedicated sensors for level, temperature and lng density measurements, all embedded into a robust stainless steel housing. All components exposed to Zone 0 & 1 are constructed of stainless steel, offering superior corrosion resistance. The SI-7000 now features an entirely re-designed jam-proof vertical-gear-drive mechanism (VGD), combined with a robust stainless steel chain resulting in trouble-free most reliable profiling performance in LNG & LPG storage tanks.
Some of the key features of the Model SI-7000 LTD Tank Gauging System include:
- Level, temperature, and density of LNG 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
