Liquefied petroleum gas (LPG) is a hydrocarbon gas consisting primarily of propane, butane, or a mixture of both. Because it produces lower greenhouse gas emissions than traditional solid fuels, there's increasing demand for LPG across the world. In fact, some governments have implemented policies and initiatives to promote the use of LPG to reduce air pollution and improve public health. This increased demand puts the onus on storage terminals to use their capacity as efficiently as possible, by optimizing inventory management and safety. This can be achieved by integrating non-contacting radar level gauges into tank gauging systems.

Control’s editor-in-chief, Len Vermillion, spoke with Tomas Hasselgren, manager of global business development at Emerson, about the challenges of LPG tank gauging, and the benefits that can be achieved by using non-contacting radar level gauges rather than traditional level measurement technology.
