Guided Wave Radar: Correct Installation is the Key

GWR is easy to install and provides an accurate and reliable measurement for both level and interface. It is suitable for a wide variety of applications and provides a top-down, direct measurement. These features make GWR level transmitters an ideal choice for replacing traditional level devices as they can be used with liquids, sludge’s, slurries and some solids. A key advantage of radar is that no compensation is necessary for changes in density, dielectric, or conductivity of the fluid. Even more, changes in pressure, temperature, and vapour space conditions generally have little impact on accuracy. In addition, radar devices have no moving parts, so maintenance is minimal.

To achieve the best results and protect the GWR against damage, correct installation is important and dealing with the possible problems caused by noise is a vital aspect of the installation process. Providing the manufacturer’s recommendations are followed, correctly installed GWR level measurement devices will enable higher performance, lower maintenance and higher reliability. Tighter process control means that GWR will also help plants meet their environmental and safety requirements.
