Industries and Applications
Case1: Coal fly ash (height:29 m)
Application problems
The client requires reliable level measurement for the coal fly as with high temperature. The high temperature will cause fly ash above the surface which will serious impacted the measuring accuracy. Furthermore the fly ash will accumulate after a period. The buildup on the antenna obstruct the microwave emitted from the sensor.
Solutions
CONNETECH recommended high frequency pulse radar level sensor CPR6800 with swiveling holder and air purge for the following reasons:
  • High frequency wave can reflect most of the signal from low dielectric constant due to strong power. And the power is strong enough to penetrate the fly ash and reflect back to the receiver.
  • The paraboloid antenna can resist the interference of fly ash and air purge can clean the antenna on time.

Case2: Clinker vessel (height:18 m)
Application problems
The power generation requires reliable level measurement for the clinker vessel. The difficulty is the serious flying dust. It will cause serious interference to radar microwave. Furthermore the flying dust will accumulated around the sensor which will reduce emitting energy.
Solutions
CONNETECH recommended high frequency pulse radar level sensor CPR6800 with paraboloid antenna with air purge for the following reasons:
  • The high frequency microwave can penetrate the fly ash and reflect back to the receiver.
  • The paraboloid antenna has good result in gathering energy and the energy is stronger than horn antenna. The measuring result will not be affected by flying dust. And the air purge can clean dust around the sensor.
