Product overview
The Rosemount 5408 is an advanced radar transmitter for continuous, non-contact level measurement of liquids and solid materials. It provides reliable measurement in demanding tanks where condensation, vapour, foam, dust or aggressive media may affect conventional instruments.
Its strong radar signal, intelligent echo processing and onboard diagnostics make it suitable for critical marine, offshore and industrial tank-measurement applications. Official Emerson product page.
