Featured Cryogenic Magnetic Level Gauge Applications

Cryogenic magnetic level gauges are primarily designed for measuring the levels of liquid media at extremely low temperatures, down to -196℃, such as liquid oxygen (-183℃), liquid nitrogen (-196℃), and liquid argon in storage tanks. Common applications include:

  • Air Separation: Used to measure the levels of liquid oxygen (-183℃), liquid nitrogen (-196℃), and liquid argon in storage tanks.
  • Liquefied Natural Gas (LNG): Used for level monitoring in LNG storage tanks, refueling stations, and tank trucks; operating temperatures are typically around -162℃.
  • Cryogenic Reactions in Chemical Industry: Used to measure the levels of media such as liquid ethylene and liquid ammonia in certain chemical processes that require reactions at extremely low temperatures.
  • Superconductivity and Scientific Research: Used in extremely low temperature environments such as liquid helium or liquid hydrogen (although these applications are more specialized).
