Radar level transmitters provide non-contact level measurement. All radar level detectors send microwave beams, emitted from a sensor, to the surface of the liquid in a tank. The electromagnetic waves returns back to the sensor after hitting the surface of the fluid. Radar is the preferred technology for level measurement in many of today’s industrial applications. Newer high-frequency technology (80 GHz) offers advantages in certain application to older low (10 GHz) and mid-frequency (24 GHz) technologies. Selecting the best microwave frequency for your application is crucial. In as much, understanding the relationship between frequency and beam angle is very important.
In this video, Jeff Blair, Offer Manager for level products at Schneider Electric, presents the difference in beam angle at various frequencies. He also demonstrates how to use Beam Angle Calculators to determine beam width at various places in a tank or vessel.
