Weightrac 31 Radiometric Flow Sensor
Brand: VEGAThe WEIGHTRAC 31 is a radiation-based sensor for precise flow measurement of bulk solids.
It is designed for mass flow determination on conveyor belts in all industries.
Due to its frame construction, the WEIGHTRAC 31 can be simply retrofitted on the conveyor belt.
Features- Wear-free, because non-contact measurement
- Exact determination of the delivery volume through simple setup
