Radar Tank Gauge for Asphalt and Bitumen tankers - GL-300
GL-300 Tank Monitoring System for Asphalt and Bitumen tankers consists of the GLA- 300/H Radar Tank Gauge, the GC-300 Cargo Temperature Unit and the GLK- 300 Signal Processing Unit.
The KONGSBERG Radar Tank Gauge, GLA- 300/H, is designed with a horn antenna using a PTFE plate to isolate the radar electronics from the tank atmosphere. In combination with a specially designed angular adapter, the Radar Tank Gauge avoids direct radiation heat from the cargo. This reduces the exposure to the high temperature and increases the life span of the electronics inside the GLA-300/H housing. 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 Tank Gauge includes a patented signal detection method that ensures optimum performance. A frequency sweeping microwave signal is emitted by the Radar, and by aid of the angular adapter 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.
The Radar Tank Gauge adapts to an angular adapter with inner diameter of 200 mm. The angular adapter shall be welded to the top of the tank, preferably as close to the centre of gravity of the tank as possible.
Optional 1" sounding plug is available on the inspection hatch of the adapter.
