ABB Guided Wave Radar Level Transmitters

ABB guided wave radar (GWR) transmitters—such as the LWT310, LWT320 and MT5000 series—deliver precise, reliable level measurement for liquids, slurries and interfaces, even under challenging process conditions. By guiding microwave pulses down a probe, these devices maintain strong signal energy, ensuring stable and accurate readings in applications involving vapor, pressure changes, temperature fluctuations or turbulence.

The latest LWT series enhances measurement performance with ABB’s advanced LevelExpert™ algorithm, designed to accurately track level even in vessels with heavy internal obstructions or process noise. With no moving parts and minimal maintenance needs, these transmitters offer long-term dependability for industries including oil & gas, chemicals, water treatment, power, and more.

Key advantages include:

• Unaffected by temperature, pressure, density or vapor changes
• Easy installation and commissioning
• Reliable operation in vacuum conditions
• Consistent signal return, even with light coatings
• Integrated waveform diagnostics (Scope Trace)
