The Formidable Team of Guided Wave Radar and Non-Contact Radar

Radar technology has revolutionized level measurement in a variety of process industries since the introduction of 4-20mA loop powered, radar-based transmitters in the 1990s. Both guided wave radar (GWR) and non-contact radar have numerous advantages over older, more established level measurement technologies. In a recent article for Industrial Products Process and Technology Magazine (IPP&T), Magnetrol® Global Product Manager Bob Botwinski discusses the benefits of using these radar technologies versus traditional level instrumentation, and how guided wave radar and non-contact radar can work together to provide reliable level measurement. Here’s an excerpt from the article:

Magnetrol® guided wave radar and non-contact radar instruments.

Both guided wave radar and non-contact radar have the same general principle of operation (microwave time of flight) and no moving parts. Because of this, users can retrofit these ra­dar transmitters into various process applications and see improvement in efficiency and accuracy, including applications that use these technologies:

  • DPs, due to SG shifts, installation cost, and leak points
  • Buoyancy, due to SG shifts, moving parts, cali­bration issues, and cost
  • RF Capacitance, due to cumbersome calibra­tion, dielectric shifts, and coating issues
  • Ultrasonics, due to vapor effects, turbulence, and foam

Guided wave radar and non-contact radar are related technologies, and together they are a powerful combina­tion that can cover the majority of your continuous level control needs. A very similar user interface and quick disconnect electronics means that, if you know how to use one, you’ll know how to use the other.

More Information

The IPP&T article contains an overview of the two technologies, the best applications for each technology and information about what to look for when selecting a radar-based device. In addition, MAGNETROL has created a radar solutions site with more information on both guided wave radar and non-contact radar level control technologies.
