    How do I choose the right guided wave radar (GWR) probe?
    Choosing the proper Guided Wave Radar (GWR) probe is the most important decision in the application process. The probe configuration establishes fundamental performance characteristics. Coaxial, twin element (rod or cable) and sin-gle element (rod or cable) are the three basic configurations used today; each with specific strengths and weaknesses.

    What is a GWR probe used for?
    These are good general purpose probes that are typically used in longer range applications, or where flexible probes are required. With all radar level instruments, including GWR transmitters, the necessary condition for electromagnetic wave reflection is a sudden change in dielectric permittivity.

    What are the different types of GWR probes?
    There are 3 basic styles of GWR probes: Coaxial, single, and twin. Of these, the single and twin are available in both rigid and flexible forms [ rigid single, flexible single, rigid twin, flexible twin ]. The advantage of the coaxial probe is that it will not be impacted by nearby objects or narrow, restrictive nozzles.

    What is a single rod probe?
    The single element rod probe is the least efficient and exhibits the greatest energy losses. However, single rod probes are more tolerant of process fouling than two-rod or coaxial probes, where viscous liquid or solid matter may cling to the wave guide.

    What is a guided wave radar (GWR) liquid level measurement sensor?
    Guided wave radar (GWR) liquid level measurement sensors have been on the market since the mid to late 1990s, though it is still considered by many as a new technology. GWR can be used in a wide range of applications and media including solids and liquids. Guided wave radar transmitters are very commonly used in liquid interface level measurement.

    Are GWR probes contacting or non-contact?
    Coating/Clogging/Buildup/Bridging: As a contacting technology, certain GWR probes can suffer error due to various degrees of process media coating. "There is no ideal level measurement technology," says Botwinski. "In a perfect world, all level measurement would be non-contact, perhaps even non-invasive."
