Spiral Vortex Flowmeter With Wide Range Ratio And Strong Anti-Interference Ability For Gases And Steam
The spiral vortex flowmeter is a high-precision velocity-type flow measurement instrument based on fluid dynamics principles. It measures flow by detecting the swirl frequency generated when the fluid passes through the helical guide vanes.
| Characteristics | Spinning Vortex Flowmeter | Volumetric Flowmeter (Oval Gear/Wafer Gear/Twin Rotor) |
|---|---|---|
| Principle | Fluid vibration (vortex oscillation frequency) | Mechanical volumetric displacement (fixed volume counting) |
| Internal Structure | No mechanical moving parts (only fixed blades and sensors) | Has precise mechanical moving parts (gears, rotors) |
| Emphasized Advantages | High reliability, long service life, suitable for dirty gases | High accuracy, insensitive to viscosity, no need for straight pipe sections |
| Emphasized Disadvantages | Requires straight pipe sections, sensitive to vibration, medium to high pressure loss | Prone to solid particles (can get stuck), high pressure loss, mechanical wear |
| Main Applications | Gases, steam | High viscosity liquids (such as crude oil, heavy oil) |
The helical vortex flowmeter is particularly suitable for the measurement of gases and steam, and can also be used for the measurement of some liquids.
The helical vortex flowmeter is a robust and durable flow measurement instrument based on fluid mechanics principles. It has dominated the gas and steam metering fields due to its design without moving parts, wide range ratio, and direct output of frequency signals. Although it has certain requirements for installation conditions (straight pipe sections) and pressure loss, its high reliability and excellent overall performance make it a very popular choice in industrial processes.
