What is a radar level gauge? In what applications is it used? What are its advantages? Let the engineers from Dinghua Electronics provide you with detailed answers. Let’s learn together! 1. What is a radar level gauge? The DHE-RD series of radar level gauges can be widely used for measuring the level of liquids and solids. It can continuously measure the level of various media even under conditions of high pressure, strong corrosivity, strict hygiene requirements, or extreme operating conditions. The DHE-RD series of radar level gauges are divided into contact (guide wave) radar level gauges and non-contact radar level gauges, depending on the measurement purpose, properties of the material, and diameter of the storage tank. Radar level gauges use electromagnetic wave pulses for measurement; they operate at a frequency of 26 GHZ, have low beam energy, and can be installed in various metal and non-metal containers or pipes to continuously measure the level of liquids, slurries, and granular materials. Suitable for environments with large fluctuations in dust, temperature, and pressure, as well as those containing inert gases and steam. Radar level gauges cause no harm to humans or the environment, and they are not affected by the specific gravity of the medium or changes in its dielectric constant; moreover, they do not require on-site calibration. Radar level gauges transmit and receive extremely short microwaves with very low power through an antenna system. Radar waves travel at the speed of light. Operating time can be converted into a level signal through electronic components. A special time extension method can ensure stable and accurate measurements in an extremely short period of time.
