Radar is the fastest growing technology for level gauging in LNG tanks. No wonder – in a huge, cryogenic tank that may not be opened for years, you need a level gauging system designed to be maintenance-free and highly reliable.
Rosemount TankRadar Rex measures the LNG level without any physical contact with the LNG surface, and without the need for inside-tank components that require service. Thus, the system provides continuous, reliable and highly accurate level data, for the entire service life of the LNG tank.
To reliably measure the level in an LNG tank, a radar gauge needs a sufficiently strong echo from the LNG surface. Rosemount TankRadar Rex handles the challenge superbly. The advanced signal processing design, featuring a highly sensitive radar receiver, uses FMCW radar which gives optimum signal strength from the LNG surface. The 4-inch still-pipe guides the radar signal, resulting in a strong undisturbed echo from the liquid surface.
A patented reference device mounted inside the still-pipe enables measurement verification with the tank in operation. This eliminates the need for expensive calibration chambers and large-size valves.
