Microwave barrier emitter
Soliwave FQR57

Transmitter for non-contact point level detection and bulk flow monitoring

The Soliwave microwave barrier uses a non-contact procedure for detection of point levels and bulk flow (flow / no flow, trend). The device is also suitable for detecting and counting objects, detection of deposits as well as monitoring of filling processes and material transfer points. It can be installed in containers, conduits, hoppers, filling stations, shafts, filters or on free fall shafts. It is possible to take a measurement through non-metallic container materials from the outside.


  • Simple assembly with R 1½, 1½ NPT thread or G 1½ (with lock nut)

  • Mechanically robust construction 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

  • Increased safety of the point level monitoring by optional integrated bulk flow monitoring

  • Measuring principle almost independent of the process properties

  • Can also be used in difficult applications, where other measurement methods fail

  • Easy operation via the Nivotester FTR525 with graphical display saves time and reduces costs

Campo de aplicação

Non-contact (wear- and maintenance-free) limit detection (min/max) and flow monitoring (flow/no flow, trend) for bulk solids.

  • Detecting, counting and positioning of objects

  • Detection and analysis of deposits and contamination in filters

  • Monitoring of filling processes

  • Monitoring of material transfer points

  • For high temperature applications up to 450°C (+842°F)

  • For high pressure applications up to 20bar (+290psi)

  • International explosion protection certificates
