Differences in the application of servo level gauges and radar level gauges

1. The servo level gauge can not only measure the liquid level of the medium, but also perform functions such as density measurement, oil-water interface detection, as well as measurement of the average density and density distribution of the medium. However, when the viscosity of the medium being measured is high, and it exhibits wall-adhesion and viscosity-related properties, servo level gauges yield significant measurement errors; they are not suitable for measuring the level of such media, and moreover, these level gauges are relatively expensive. 2. Radar level gauges have many advantages: they can measure liquids, solid media, volatile liquids, etc., and are not affected by factors such as noise, steam, dust, or vacuum. They are also unaffected by changes in the density or temperature of the medium. Additionally, they feature high measurement accuracy, a small blind zone, easy maintenance, and strong stability.
