Radar Tank Gauge for Slop tank, Still pipe solution - GL-300

GL-300 Tank Monitoring system for Slop tanks or applications with still pipes consists of the GLA-300/HS Radar Tank Gauge, the GC-300 Cargo Temperature Unit and the GLK-300 Signal Processing Unit.

GLA-300/HS radar tank gauge for Slop tank – Still pipe solution.

The KONGSBERG Radar Tank Gauge, GLA- 300/HS, is designed with a horn antenna using a PTFE plate isolating the radar electronics from the tank atmosphere. The horn antenna diameter is designed to fit a still pipe with a 3,5" inner diameter. The antenna comes with a 0,7m top pipe section with facilities for internal cleaning of the pipe surface. 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 atmospheric conditions inside the tank.

Key features

  • Applicable for slop tank where obstructions prohibit free radar beam
  • 3,5" standpipe
  • Radar RMS accuracy 5 mm
  • Measuring range 0 to 50 m
  • Operating temperature -45 to +85 °C
  • Environmental protection IP 66/67
  • Intrinsically safe Ex ia IIC T4
  • Stainless steel AISI 316 L
  • Integrated tank pressure transmitter

Principle of operation

The Radar Tank Gauge employs the Frequency Modulated Continuous Wave (FMCW) principle with dual sweep technology to eliminate Doppler-effect caused by cargo movement. 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.

Tank installation

The Gauge adapts to a Gauge Socket with inner diameter of 200 mm or larger. 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.

Optional sounding plug requires a Gauge Socket diameter from 400 mm and above. Also, if strict cleaning of tank equipment is essential, a larger diameter socket than 200 mm is preferable.

For slop tank solution with standpipe 3.5" the top section of the standpipe installed inside the Gauge Socket is Kongsberg Maritime supply. The pipe sections to follow are normally yard supply.

Tank pressure transmitter

The GT-450 tank pressure transmitter is fully integrated in the Radar Tank Gauge. The only installation work needed is to connect the cable to the terminal block, the rest is performed before delivery. The GT-450 pressure transmitter is built around a dry, robust ceramic measurement capsule with internal capacitive sensing and with a ratiometric output. The ceramic capsule is "burned in" during the manufacturing, giving a transmitter with very good long term behaviour.
