  • The Soliwave FQR50 microwave barrier uses a contact-free procedure for detection of point levels. It can be installed in containers, conduits, shafts or on free fall shafts. It is possible to take a measurement through non-metallic container materials from the outside. Suitable as point level switch for controlling and counting all types of bulk solids. It interacts with the Soliwave FDR50 receiver.

    • Very reliable measurement thanks to adjustable sensitivity and indication of the signal strength on the receiver
    • Mechanical robust solution ensures cost savings over the whole life cycle of the product: No wear and tear, long serviceable life, maintenance free
    • Safe solution unaffected by process conditions and even suited for hazardous areas

    Typical bulk solids are: Wood chips, wood dust or flour, plaster, cement, ash, paper or cardboard shred, gravel, sand, dried powders in general, bags, boxes.
