How It Works

The Rosemount 3408 uses 80GHz Frequency Modulated Continuous Wave (FMCW) and Smart Echo Supervision⢠technologies, as well as smart algorithms to maximize measurement accuracy and reliability, even in small tanks and challenging fast-filling vessels. â
FMCW technology deploys a continuous echo to maximize radar signal strength and produce a more robust and reliable measurement. And Smart Echo Supervision tracks all echoes, including those from obstructions vessels, and distinguishes them from the real product surface echo. This ensures the true product level is reliably and accurately reported.â
