Liquid Density Meter for LNG Tanks
When LNG of one density is fed into a tank containing LNG of another density, the two may form different layers. This can result in the generation of a large quantity of boil-off gas (BOG) when one layer suddenly disappears, a phenomenon known as “rollover.” LNG tank liquid density meters are therefore used to monitor the LNG inside tanks to prevent rollover from occurring.

〔Liquid density meter for existing tanks〕
The LNG tank density meter can measure the density and temperature of LNG at all levels by means of a density sensor that moves up and down in the tank. They are of two types: one for new tanks, and another, which uses a tank’s reserve nozzle, for existing tanks.
