Segmentation Analysis

By technology

The global market is segmented into contact and noncontact systems. Industrial processes employ contact radar level transmitters, a level measurement device, to ascertain the volume of a substance (such as bulk material or liquid) within a tank or vessel. A contact radar level transmitter operates by directing the radar signal toward the surface of the substance under consideration, thereby establishing direct contact with it. This opposes noncontact radar level transmitters, in which the radar signal reflects off the vapor vacuum or foam layer above the substance rather than coming into direct contact with its surface.

Contact radar level transmitters are frequently employed in situations involving substances that are difficult to measure, dense, or subject to conditions that could impede noncontact measurements. In such situations, measurements can be more reliable through direct contact with the substance.
