Applications
The Nivotester FTR525 process transmitter works with Soliwave FQR57/FDR57 microwave barriers for point level detection and bulk material flow monitoring (presence/absence, trend analysis). The system can also detect and count objects, identify buildup, and monitor filling operations and material transfer points. Suitable for installation in tanks, pipes, silos, loading stations, ducts, filters, or vertical chutes.
Non-contact (wear-free, maintenance-free) solution for level limit detection (minimum/maximum) and flow monitoring (material presence/absence, trend analysis) in bulk solids handling.
