Emerson Rosemount 5900S Series, Reference Manual, Page: 13 / 298

2 Overview
2.1 Introduction
The Rosemount
™
5900S is a two-wire radar level gauge for high accuracy non-contact
measurements. The level gauge continuously emits a radar signal with varying frequency
towards the product surface. This allows very accurate level measurements by processing
the difference between the frequencies of the emitted and received radar signals.
The Rosemount 5900S is an integral part of the flexible Rosemount Tank Gauging system.
The advanced and robust design makes it suitable for a vast range of applications. It is
designed for high accuracy level measurements as well as handling complex tank shapes
and obstacles in the tank that may interfere with measurement signals.
