Both Swirl flow meters and Vortex flow meters belong to the category of fluid vibration flow meters, but their core differences lie in their working principles and the resulting application scenarios.
| Comparative Dimension | Swirl Flow Meter | Vortex Flow Meter |
| Working Principle | Forced fluid rotation, detecting the frequency of “vortex precession” | Natural generation of Karman vortex street, detecting the frequency of vortex alternating release |
| Applicable Media | Gases
(such as natural gas, air, and coal gas) |
Gas, Liquid, Steam |
| Advantage | 1.Good measurement performance for low flow and low velocity gases
2.High tolerance to slightly dirty gases 3.High pressure gas operating conditions |
1.Low pressure loss, energy-saving
2.Wide range ratio, adaptable to a wide range of flow changes 3.One of the preferred solutions for steam measurement |
| Installation Requirements | The requirements for the straight pipe section are relatively low.
(usually ≥ 3-5DN in the front and ≥ 1-3DN in the back) |
High requirements
(usually front ≥ 10-20DN, rear ≥ 5DN) |
