Radar Tank Gauge (RTG)

The KONGSBERG Radar Tank Gauge (RTG), GLA-310/5

FUEL, is designed to measure level in tanks containing lique

fied gases. Accurate measurement is possible regardless of the

tank atmospheric conditions. Flexible hardware and software

modules ensure easy adaptation to all tank designs.

The RTG consists of a microwave antenna and an electronic

unit. The electronic unit includes a sophisticated signal detec

tion method that ensures optimum performance, which com

bined with its superb signal-to-noise ratio offers the highest

measurement reliability and accuracy.

The horn antenna is designed to guide a frequency sweeping

microwave signal through a 50 mm standpipe. The distance is

derived from the time delay of the reflected signal.

The standpipe has ventilation holes allowing the vapour pres

sure inside and outside the pipe to stabilize, thus allowing the

liquid to rise or fall in the pipe. The standpipe is considered an

integrated part of the level gauge, and is delivered to match the

total tank height.

The RTG is specially designed to withstand the severe mechan

ical and physical conditions in a maritime environment. Only

AISI 316L acid-resistant steel and PTFE/PEEK materials are

used.
