The KONGSBERG Radar Tank Gauge, GLA- 300/H, is designed with a horn antenna using a PTFE plate isolating the radar electronics from the tank atmosphere. The clean surface antenna design is easy to clean and eliminates risk of deposits from various chemicals after tank cleaning. The radar technology provides accurate measurement regardless of the atmospheric conditions inside the tank. The Radar Tank Gauge introduces modern and flexible arrangements for simple installation. The tank pressure transmitter is fully integrated mechanically, electronically and cabling wise. The radar technology provides accurate measurement regardless of the atmospheric conditions inside the tank.

Principle of operation

The Radar Tank Gauge employs the Frequency Modulated Continuous Wave (FMCW) principle. The distance (i.e. ullage) is derived from the time delay of the reflected signal. The electronic unit in the Gauge includes a patented signal detection method that ensures optimum performance.

A frequency sweeping microwave signal is emitted by the Radar, and directed vertically down the tank.

Tank pressure

The GLA-300/H comes with a tank pressure transmitter fully integrated in the Radar Tank Gauge, ready installed before delivery. No extra installation work is required at the yard.

The GT-450 pressure transmitter is based on a dry, robust ceramic measurement capsule with internal capacitive sensing and with a ratio metric output.

Tank installation

The Radar Tank Gauge adapts to a gauge socket with inner diameter of 200 mm. The gauge socket shall be welded to the top of the tank, preferably as close to the centre of gravity of the tank as possible.
