Flow Measurement Instruments Used for Arc Furnace
Flow monitoring is critical for cooling water systems, gas conveying systems, and energy management. SAF and EAF require monitoring of cooling water flow, gas flow, oxygen flow, and argon flow.
| Type | Measuring Principle | Applicable Media | Turndown Ratio | Accuracy | Applications |
|---|---|---|---|---|---|
| Electromagnetic Flowmeter | Faraday's Law | Conductive liquid (≥2.5μS/cm) | 10:1~100:1 | 0.5%~1.0% | Cooling water, conductive liquid flow |
| Vortex Flowmeter | Karman vortex | Gas, steam, low-viscosity liquid | 10:1~20:1 | 1.0%~1.5% | Steam, gas, oxygen flow |
| Thermal Mass Flowmeter | Thermal diffusion | Gas | 50:1~100:1 | 1.5%~2.0% | Gas, argon, nitrogen mass flow |
| Differential Pressure Flowmeter | Orifice pressure drop | Gas, liquid, steam | 3:1~4:1 | 1.5%~2.5% | High temperature, high pressure, e.g., steam flow |
| Coriolis Mass Flowmeter | Coriolis force | Liquid, gas, slurry | 100:1 | 0.1%~0.2% | High-precision mass flow |
| Type | Setting Range | Contact Rating | Protection Class | Applications |
|---|---|---|---|---|
| Vane Flow Switch | 0.5~10m/s | 5A/250VAC | IP65 | Cooling water no-flow alarm |
| Thermal Flow Switch | 0~5m/s | 0.5A/24VDC | IP67 | Gas/liquid low flow alarm |
| Piston Flow Switch | 0.5~15L/min | 3A/250VAC | IP65 | Lubrication system flow monitoring |
| Flow Measurement Scenario | Recommended Instrument | Selection Reason |
|---|---|---|
| Cooling water (conductive) | Electromagnetic flowmeter | No pressure loss, high accuracy, unaffected by temp/pressure |
| Cooling water (non-conductive/ultrapure) | Ultrasonic flowmeter | Non-contact, no pressure loss |
| Steam flow | Vortex flowmeter / DP flowmeter | High temp resistance, simple structure |
| Gas/Oxygen/Argon | Thermal mass flowmeter / Vortex flowmeter | Direct mass flow, fast response |
| High-precision batching | Coriolis mass flowmeter | Highest accuracy, simultaneous density measurement |
| No-flow alarm | Flow switch | Simple, reliable, low cost |
