World-class LNG tank gauging for the Oil and Gas industrySafe and efficient inventory management is about far more than simply choosing the right sensor. A typical liquified natural gas (LNG) tank requires a whole suite of instruments to measure liquid level and density, not forgetting product temperature and pressure, surface temperature and more. For safer operations, plant engineers must also make sure that different layers of LNG densities are not mixing rapidly as this would release large amounts of gas – known as rollover.
