Advantages of guided-wave radar level gauges
Thread Content
Technical advantages of the guided-wave radar level gauge: Radar level gauges enable continuous level measurement of liquids, particles, and slurries. The measurement of radar level gauges is not affected by changes in the medium, temperature variations, inert gases and steam, dust, foam, etc. The radar level gauge has an accuracy of 5 mm and a range of 60 meters; it can withstand temperatures up to 250 degrees and pressures of 40 kilograms. It is suitable for use in areas with explosion hazards. In a guided wave radar level gauge, the electromagnetic pulses travel at the speed of light along the steel cable or probe. When they encounter the surface of the medium being measured, some of these pulses are reflected back, forming echoes that return to the pulse transmitter along the same path. The distance between the transmitter and the surface of the medium being measured is proportional to the time it takes for the pulses to travel between them. The polarity and amplitude of the echoes depend on the dielectric constant εr of the upper and lower media.
