Ultra robust, ultra precise

mecorad’s level series is designed to withstand the most extreme conditions. Even directly above a mold, tundish or ladle, the ultra robust sensor accurately measures levels and freeboard reliably in real time.





Use of the level series

The level series is set up to give you precise real-time information on levels or freeboard of hot metals and slags. Via the integrated Modbus/TCP interface measurement results are communicated directly to the PLC.


The level series works accurately and with low maintenance even under extreme heat, dust, thermal radiance or molten metal sparks up to a distance of 20.000mm. A variable opening angle of min. +-2° is suitable even for narrow viewing channels to the liquid. Micrometer accuracy for highest precision levels is available.



Due to its robust design, protected housing at IP 68 rating and available cooling options, mirrors or ceramic shields, the level series can be gauge right above the ladle or tundish. The sensor can easily be adapted to existing installations. Drillings on the back and  on the base of the housing support fast installation.
