Continuous accuracy for continuous processes.
Long-term accuracy. Minimal drift.
- Material Loading – Bulk material is fed onto the moving conveyor belt via hopper or chute.
- Weight Measurement – Two high-precision load cells measure belt load (kg/m).
- Speed Measurement – Rotary encoder monitors belt speed (m/s) in real-time.
- Flow Calculation – PLC calculates instantaneous flow rate:
Flow Rate = Belt Load × Belt Speed - Comparison – Actual flow compared to operator-set setpoint.
- Correction – Any deviation triggers VFD to adjust belt speed, maintaining target flow.
- Totalization – Cumulative throughput displayed and recorded.
- RS-485 Interface
Enables remote monitoring, data logging, and printouts with SQC (Statistical Quality Control) Analysis for quality management. - Batch Controller Integration – For totalized batch dosing applications.
- Inlet Flow Aid Devices – Vibratory trays, agitators, or screw feeders for consistent material feed.
- Dust Enclosures & Extraction Points – For clean operation with dusty materials.
- Corrosion-Resistant Construction – SS304/SS316 or coated surfaces for corrosive environments.
- Explosion-Proof Design – ATEX certification for hazardous areas.
- High-Temperature Belts – For hot materials like clinker or sinter.
- Touchscreen HMI – Real-time flow display, trending, diagnostics, and recipe management
- Advanced PID Tuning – Self-adaptive or manual tuning for optimal control response
- Data Logging – Stores flow totals, alarms, and calibration records
- Remote I/O & Networking – Integrates with plant DCS/SCADA systems
- Alarm Management – Belt slip, overload, blockage, and calibration alerts
