Over 40 years ago, Gauging Systems Inc. (GSI) started as a scrappy service and repair team, diving deep into the world of tank gauging with a relentless drive to solve real-world challenges. We didn't just fix systems-we studied them, uncovered their flaws, and dared to dream bigger. That spark of ingenuity ignited a revolution, transforming GSI into a trailblazer in the tank gauging industry. From inventing the game-changing MTG “Multi-function Tank Gauge” to pioneering the MMP “Multi-Media Probe,” we've redefined precision, safety, and efficiency for bulk liquid storage. Our cutting-edge solutions slash costs and elevate performance, making us the go-to partner for petroleum, petrochemical, and beyond.

Our offerings cover the full spectrum of tank monitoring and production needs:

  • Liquid Tank Gauging (product quantity and quality)
  • Overfill and Rupture Protection
  • Leak Detection (unauthorized product movement)
  • Vapor Monitoring (emissions, PRV, and blanket systems)
  • Tank Bottom and Roof Movement Detection
  • External Floating Roof (EFR) Water Accumulation Monitoring
  • Mixing Optimization and Electrical Savings
  • Communications HUBs (bridges legacy or competitor gauges)
