Radar Level Measurement Innovations

Emerson’s Mark Bett and Sara Anderberg presented Making Level and Life a Little Easier, a New Non-Contacting Radar for Your Industry Needs, at the 2024 Emerson Exchange Conference in Düsseldorf, Germany. Here is their presentation abstract:

While the benefits of radar level measurement are widely acknowledged, leading to the technology’s fast-growing adoption across multiple industries, radars are still sometimes perceived as being complex to commission, operate and maintain. Join this session and see how the new Rosemount 3408 Level transmitter addresses these concerns. Discover innovative features designed to save time, maximize efficiency and increase safety at every step of your process.

Rosemount non-contacting radar level measurement device echo curveAll Rosemount non-contacting radar level measurement devices use Frequency-Modulated Continuous-Wave Radar (FMCW) to identify all the echoes. The FMCW technology eliminates the overall background noise, so the signal processing task becomes solely a matter of determining which of the echoes returning to the device is the true surface echo.

The Rosemount 3408, 1408, and 1208 Radar Level Transmitters feature 80 GHz Fast Sweep Technology for increased measurement reliability. With the latest radar-on-a-chip technology and higher integration in the electronics, these sensors send more sweeps each second to ensure that you get the clearest view of the media surface.

The Rosemount 3408 non-contacting radar can use Bluetooth for startup and simple commissioning. Smart diagnostics with continuous health monitoring and process data storage can help to maintain efficient operations. Radar Signal Quality Metrics can alert for conditions such as antenna buildup or foaming at the level.

Smart Meter Verification helps verify accurate level measurements. Verification in situ occurs on-demand or can be scheduled. A verification report is automatically generated. These reports support operations with documented device verification to help maximize plant uptime and keep personnel out of hazardous locations.

The Rosemount 3408 Smart Echo level test compares the physical echo curve with the digital echo curve to test the measurement electronics and output circuitry in these level measurement devices. The digital echo is set at the level to be tested, and a proof test is conducted.

The electronics are designed to be modular and easily replaceable to simplify maintenance. Only two electronic parts, the electronics box and LCD display, match any device housing options. To reduce complexity, there is a single pre-calibrated cassette type for all hazardous location approvals. This design eliminates the need to exchange the entire housing or break the tank seal.

In summary, the Rosemount 3408 non-contacting radar delivers increased measurement reliability, reduces the risk of human error, and simplifies the ongoing maintenance required. Visit the links above for more about improving your process’s performance with better level measurement technology.
