3. KROHNE solution

An OPTIWAVE 6300 radar level meter was used for continuous, non-contact measurement. When it came to the antenna, a polypropylene drop antenna (specifi cally designed for solid applications) with a nominal size of DN80 was used. The device was placed directly on the opening of the silo roof.

4. Customer benefits

This solution allows the operator to monitor the cement

level at any time and thus eliminates any danger of putting

the production process at risk.

The OPTIWAVE 6300 provides stable, reliable measurement despite the harsh conditions in the silo.The ellipsoidal and completely enclosed shape of the antenna as well as its smooth surface prevent dust deposits on the antenna. No special dust protection or

flushing system is required and the antenna features no moving parts. This eliminates the need for regular maintenance.

The low reflective surface of the product is reliably measured thanks to the high signal dynamic of the device. The FMCW technology is not affected by the angle of repose which means that the antenna does not have to be laboriously aligned. The device comes pre-confi gured; at the time of on-site start-up, only a few parameters such as silo height, block distance and cone shape were input per device.
