Description

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.

1. Flow Meter

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

2. Flow Switch

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

3. Flow Instrument Selection Reference

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
