Correlation-based flow measurement for hot, heavily dust-laden gases.
Product overview
The principle: measure time, not pressure
The system measures the time of flight of the signal patterns created by the particles carried in the gas itself. Being a time measurement, it is accurate and drift-free over the whole life of the equipment, with no K-factors and no auxiliary pressure or temperature measurements.
Where dust is the problem, here it is the signal
The measurement remains accurate with dust loads up to 2500 g/m³ and gases up to 1000 °C, with no purging and no cleaning, and the plausibility of the raw signals is supervised continuously.
Main advantages
- Digital online measurement with ±2% accuracy.
- Gas temperatures up to 1000 °C and dust up to 2500 g/m³.
- Drift-free: no calibration, no purging, no K-factors.
- Virtually maintenance-free; payback in under 3 months.
- Turn-down ratio up to 25:1.
- Flange mounting and hot tapping without stopping the plant.
Versions and applications
Compact, SIL and Portable
The Compact version is the fixed single-channel solution with 4-20 mA outputs for velocity and volume flow. The SIL variant adds the SIL 2 certified version for safety loops, and the Portable version brings the same principle to a mobile kit with rugged cases, CSV logging on SD card, an additional 4-20 mA output and probes of several lengths.
Applications
- Cement: tertiary air, downcomer, vertical raw mill, clinker cooler, bypass and waste heat recovery.
- Steel: electric arc furnace off-gas.
- Power: primary and secondary air, flue gas and unburned carbon.
- Waste-to-energy and emission monitoring: total stack flow.
Installation without interruptions
The probes are flange-mounted, with hot tapping available, and the reading in m/s appears as soon as they are connected, with no prior calibration of the sensors.
