Principle

The radar level transmitter antenna emit narrow microwave pulse that propagate in speed of light in space, when come across the measured medium surface, its energy is partly reflected back and is received by the same antenna. The time interval of transmitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium, thereby figure out the distance from the antenna to the measured medium surface.



Features: the radar level gauge adopt transmission frequency up to 26GHz, which possesses:



- Small beam angle(minimum 5 degrees), concentrated energy, stronger anti-jamming capability, improving the measurement accuracy and reliability.

- Small antenna size for installation, and install added protective dust cover, such as the antenna device.



- smaller measuring blind zone for cannikin measurement;



- Shorter wavelength, suitable for level measurement of small particulate matter.



Apply advanced microprocessor and unique DCRDDiscovery echo processing technology for complex working conditions.



Adopt the pulse working manner, and quite low transmit power, can be installed inside a variety of metals, non-metallic container, therefore harmless to human body and environment.



Characteristic: a variety of patented antenna, anti-coagulation, anti-hanging material, the minimum emission angle is 8 degree.



Application: widely used in a variety of liquid level measurement, such as: hydrological monitoring.



Maximum range: 30m (there are 70m of other model)



Accuracy: ± 3mm
