Guided Wave Radar (GWR) level sensors—also referred to as Guided Wave Radar transmitters—leverage advanced microwave technology to deliver precise measurements of level and interface level across a diverse range of media, including liquids, solids, and slurries. These transmitters are engineered to excel in the most demanding industrial applications, where environmental conditions often pose significant challenges to traditional measurement tools.
Emerson, a global leader in industrial automation, offers a market-leading portfolio of GWR transmitters designed to address these hurdles head-on. What sets these solutions apart is their ability to maintain exceptional accuracy and reliability even in harsh operating environments—such as those characterized by extreme high temperatures, elevated pressures, or turbulent process media. Beyond performance, Emerson’s GWR transmitters also prioritize safety and cost-effectiveness, ensuring they not only meet critical measurement needs but also support long-term operational efficiency and compliance for industries ranging from oil and gas to chemical processing and food and beverage.
Whether monitoring the level of viscous liquids in a high-pressure reactor, tracking solid materials in a dusty silo, or measuring interface levels in a multi-phase separation tank, Emerson’s Guided Wave Radar transmitters provide consistent, trustworthy data that empowers operators to optimize process control, prevent overfills or run-dry incidents, and minimize unplanned downtime.
