Radar level gages

The waveguide radar is created on the basis of a scatterometry method with the temporary permission: impulses of electromagnetic energy are transferred down a probe. At achievement reflection of an impulse happens an impulse of a surface of liquid which dielectric permeability exceeds available for air or steam in which it extended. The high-speed scheme of synchronization with high precision measures time of arrival of the reflected impulse, providing exact measurement of level of liquid or limit of the section of two liquids.
