Product Details

The major applications for an RD808 canal radar level sensor include reservoir water level detection and farmland irrigation drainage. Since the RD808 canal radar level sensor's housing is composed of plastic, the price of the total item is rather reasonable.

The affordability and robustness of municipal RD808 lake radar level sensors are their main benefits. The radar antenna used for the measurement is made of materials specially used for strong acids and alkalis. The functional life of canal radar is substantially increased by this anti-corrosion design.

In spring, summer, autumn, and winter, a canal radar level sensor can achieve continuous detection. It is advisable not to install a measuring device while surveying farmland, a reservoir, etc. in an area with lots of people. When the canal radar level sensor RD808 is in use, the wires must be led out, which could provide a risk for electric shock and electric leakage.

What advantages come with measuring liquid level with radar technology?

As for water level measuring of outdoor lake, rivers, canal, shoal, etc., radar level measurement technology is widely used and recommended nowadays, this RD808 model and the traditional horn antenna radar level transmitter can be selected, but there are still some tips for model choosing, in order to reach the best measuring results.

Because radar technology has a larger detection range and a high detection accuracy. Radar technology has higher data reliability and is more stable than other technologies.

Radar level sensors have a long lifespan. After being put together, the radar transmitter is ready for operation. In general, it can be utilized without a lot of upkeep and supervision for at least four years.
