1.1 Overview

The SLG 700 Guided Wave Radar SmartLine transmitter is an electronic instrument
designed to measure levels of liquid and solid materials. Guided Wave Radar (GWR)
transmitters use time domain reflectometry with radar pulses guided by a metal probe and
reflected off a product surface to determine levels in tanks. In comparison to other level
measurement technologies, GWR provides a highly-accurate, cost-effective, reliable
measurement over a wide range of process conditions.

1.2 Transmitter Models

The SmartLine Guided Wave Radar (GWR) transmitter is available as a family of
SLG72X models for liquid applications. The pressure and temperature application ranges
for each model are summarized in
Standard Temperature Liquid Level Measurement
(-40 to 200°C/-1 to 40 bar)
High Temperature / High Pressure Liquid Level Measurement
(-60 to 450°C /-1 to 400 bar)
Each model is available with a range of probes, wetted materials, and accessories to suit
most applications.
