What device measures cargo level continuously in an LNG membrane tank using radar waves?
Direct Answer
Option A: Radar ullage level gauge
Radar ullage gauges utilize microwave pulses to measure the distance to the liquid surface without physical contact. Per IGC Code requirements for membrane tanks, these provide continuous, high-accuracy level monitoring, ensuring cargo containment integrity while minimizing the risk of mechanical failure associated with float-based systems in cryogenic environments.
