Description

Technical Field

[0001] The utility model relates to the field of radar level gauges, in particular to a radar level gauge with a protection mechanism. Background Art

[0002] Radar level meter is a general-purpose radar level meter. It is a measuring instrument based on the time travel principle. Radar waves run at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits a high-frequency pulse that propagates at the speed of light in space. When the pulse encounters the surface of the material, it is reflected back and received by the receiver in the meter, and the distance signal is converted into a level signal. It is widely used in petroleum, chemical, tap water, sewage treatment, water conservancy and hydrology, steel, coal mining, electric power and other industries. It has a wide range of applications and has a good market prospect.
