Working principle
Frequency modulation continuous wave (FMCW) technology is adopted in the object level meter of the Radar Level Meter. The continuous wave with frequency variation is transmitted within a certain period, and the echo reflected by the object has a certain frequency difference with the transmitted signal. The distance information between the target and the radar can be obtained by measuring the frequency difference.
Radar level meter, as a new industrial level measuring instrument, has the characteristics of high-temperature resistance, high-pressure resistance, vacuum resistance, strong penetration, temperature, steam, dust, and other effects.
Applications
The SKR800H is an 80 GHz FMCW Radar Level Meter for continuous level measurement of Bulk Solid, and Large range liquid application
