Microwave barrier receiver
Soliwave FDR56

Receiver for non-contact point level detection in bulk solids

  • Soliwave FDR56 ©Endress+Hauser

The Soliwave FDR56 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 FQR56 emitter.


  • Highly reliable measurement due to flush-mounted installation and possible non-contact installation as well as 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, process-wetted ceramic sensor diaphragm (optional), long serviceable life, maintenance free

  • Electronics housing can be rotated by 360°, allowing adjustment into optimum position after installation

  • Direct connection of the supply voltage (emitter and receiver separately or together)

  • Mechanically compatible to FQR50/FDR50 microwave barrier, existing process connections can continue to be used; likewise, accessories such as adapter flanges, installation brackets and sight glasses can continue to be used
