New Measurement Range 30m Flanged Connection Rosemount 3408 Level Transmitter Non-Contacting Radar for Pipe

The Rosemount 3408 is a compact, two-wire non-contacting radar level transmitter that uses FMCW technology to deliver accurate, continuous level measurements. It stands out with Smart Echo Supervision™ that tracks echoes from obstructions and reliably identifies the true product surface echo. This makes it a practical choice for reliable level monitoring and overfill prevention in various process conditions.

• Smart Echo Supervision™ automatically distinguishes real product echoes from false ones caused by tank obstructions.
• Maintenance-free non-contacting radar—no moving parts or contact with the process media.
• Safety-certified (SIL 2/SIL 3) with support for long proof-test intervals and remote testing without process interruption.
• Built-in diagnostics and Smart Meter Verification for device health checks.
• Optional Bluetooth® connectivity via Rosemount Radar Master Plus for easy configuration.
• Compact design with intuitive setup using pictorial instructions and software.
• Supports HART communication with multiple process variables output.

Measurement Principle:

FMCW (Frequency Modulated Continuous Wave) non-contacting radar.

Output Signal:

Two-wire 4-20 mA with HART protocol.

Accuracy:

±2 mm (performance standard for liquids).

Process Connections:

Various antenna options (e.g., cone, process seal); supports top-down installation.

Process Temperature:

Wide range suitable for liquids, slurries, and solids (exact limits depend on antenna type and seals).

Process Pressure:

Dependent on antenna and flange rating (typically up to high pressures for non-contact radar).

Enclosure:

Aluminum or stainless steel housing options; IP66/67 protection typical.

Power Supply:

Loop-powered (two-wire).

Certifications:

Safety (SIL 2/3), hazardous area approvals (ATEX, IECEx, etc.), overfill prevention compliance.

Diagnostics:

Smart Diagnostics Suite available; Smart Meter Verification for in-situ health checks.

Wireless Option:

Available as Rosemount 3408 Wireless variant with WirelessHART®.

Well-suited for level measurement in storage tanks, process vessels, and overfill prevention in chemical, oil & gas, water/wastewater, and other industries—especially where obstructions, turbulence, foam, or dust are present, or where maintenance-free operation is preferred.
