Rex RTG

3.1.1

Overview

The Radar Tank Gauge Rex, RTG Rex, is an autonomous distance
measuring device. The distance and level calculations are continuously
carried out in the Radar Tank Gauge. Upon request from a master the
RTG can send the level information, status and other information on the
Field Bus.

All Rex gauges consist of two main parts; the Transmitter Head (TH) and

a Tank Connection Unit. A number of different Tank Connection Units
(Antennas) can be attached in order to satisfy a variety of different
applications.

There are different types of Radar Tank Gauges:

•

The

Horn Antenna Gauge RTG 3920

, for fixed roof installation

without still pipe.

•

The

Parabolic Antenna Gauge RTG 3930

, for demanding envi-

ronments without still pipe.

•

The

Still Pipe Gauge RTG 3950

, for measuring in still pipes.

•

The

LPG/LNG Gauge RTG 3960

, for liquid gas, LPG and LNG.

All antenna types use the same kind of Transmitter Head Electronics.
