What are the differences between vortex street and turbine flowmeter?
The difference between a vortex flowmeter and a turbine flowmeter mainly lies in their working principle, applicable medium, cost, and application scenarios, as follows:
1. Differences in working principle. Vortex flowmeter: When fluid flows through non streamlined obstacles, periodic vortices (vortex streets) will be formed behind the obstacles.
. The vortex frequency is directly proportional to the fluid velocity, and the flow rate can be calculated by measuring the frequency. The formula is: f=Kv, where f is the vortex frequency, v is the flow velocity, and K is a constant related to the shape of the object and fluid properties. Turbine flowmeter: The fluid drives the turbine to rotate, and the turbine speed is proportional to the flow rate. The flow rate is calculated by measuring the speed. The formula is: Q=KN, where Q is the flow rate, N is the rotational speed, and K is a constant related to fluid characteristics and turbine design.
2. Differential vortex flow meters suitable for resolving quality issues: liquids such as water, oil, alcohol, chemical raw materials, etc. Gases: air, oxygen, nitrogen, natural gas, coal gas, etc. Steam: saturated steam, superheated steam. Characteristics: Strong adaptability to fluid types, capable of covering multiple media. Turbine flowmeter: gases: air, nitrogen, oxygen, hydrogen, biogas, natural gas, etc. Steam: Suitable for steam flow measurement. Liquids: Clean, low viscosity liquids (such as those in the petroleum, food and beverage, and pharmaceutical industries). Characteristics: High requirements for fluid cleanliness, high viscosity may affect measurement accuracy.
Fourth, other differences in measurement stability: The vortex flow meter has better long-term stability due to the lack of movable parts.
. The turbine of the turbine flowmeter may be affected by wear or accumulation of dirt, which may affect its accuracy and requires regular maintenance. Anti interference capability: Vortex flowmeter has a certain anti-interference ability against pipeline vibration (filtered through signal processing). Turbine flow meters are sensitive to fluid pulsation or impurities and require stable flow fields and clean media. Range: The range ratio of vortex flowmeter is usually 10:1, suitable for large-scale flow changes. The turbine flow measurement range ratio can reach 20:1 or higher, but high viscosity fluids may limit the range. Summary of selection suggestions: If you need to
