Vortex flowmeter principle
Choosing a flow meter
| Medium | Technology | Note |
|---|---|---|
| Saturated, superheated steam | Vortex + P/T compensation | kg/h, no moving parts |
| Gas, compressed air | Vortex, DP | P/T compensation |
| Water, wastewater | Electromagnetic | Conductive liquids |
| Thermal oil | Heat meter | Flow + 2 temperatures → kW |
| Large steam/gas lines | Orifice + DP | ISO 5167 |

FAQ
Why compensate steam for P and T?
Steam density changes with P and T; a vortex measures volume, so it must be multiplied by ρ(P, T) for kg/h.
How much straight pipe?
Typically 10–40 D upstream and ≥ 5 D downstream, depending on the disturbance.
