Product Description
Level Measurement Instruments Used for Arc Furnace
SAF and EAF require monitoring of circulating water tank level, gas holder level, and bin stock level to ensure continuous and stable system operation.
1. Level Meter
| Type | Measuring Principle | Measuring Range | Accuracy | Applications |
|---|---|---|---|---|
| Ultrasonic Level Meter | Sound wave reflection | 0~20m | 0.5%FS | Water tank level, bin stock level |
| Radar Level Meter | Electromagnetic wave reflection | 0~30m | ±2mm | High temp, high pressure, volatile liquid/solid |
| Hydrostatic Level Meter | Hydrostatic pressure | 0~100m | 0.2%FS | Water tank, non-pressurized vessel level |
| Rotary Paddle Level Switch | Rotation obstruction | Custom rod length | Switching | Bin high/low level alarm |
| Tuning Fork Level Switch | Vibration frequency change | Custom insertion depth | Switching | Fine powder, granular material level alarm |
| Plumb Bob Level Meter | Weight detection | 0~40m | ±5cm | Large bin continuous level measurement |
2. Level Instrument Selection Reference
| Measurement Scenario | Recommended Instrument | Selection Reason |
|---|---|---|
| Circulating water tank level | Ultrasonic level meter / Hydrostatic level meter | Non-contact/economical, easy installation |
| Steam drum/accumulator level | Capacitive / Differential pressure level meter | High temp and pressure resistance |
| Gas holder level/capacity | Laser / Radar level meter | High accuracy, unaffected by gas |
| Bin stock level (continuous) | Radar level meter / Plumb bob level meter | Dust-resistant, high reliability |
| Bin stock level (switch) | Rotary paddle / Tuning fork level switch | Simple, reliable, low cost |
