THE RIGHT LEVEL MEASUREMENT FOR LIQUEFIED GAS

Emerson’s Johan Sandberg explains how radar gauges support inventory management and overfill prevention in LNG and LPG tank storage applications Level measurement technology is a key component of tank gauging systems for vessels containing liquefied natural gas (LNG), liquefied petroleum gas (LPG), or other liquefied gases. Reliable liquid level measurements inside complex full containment tanks are vital for inventory management and custody transfer purposes, and to prevent overfills. In liquefied gas applications, level measurement has often been performed with servo technology. A small displacer suspended by a thin wire is connected to a servo gauge on top of the tank. […]
