2. 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 form 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.

III. Differences in Cost and Application Scenarios of Hebe family Vortex flowmeter: Cost: slightly higher than turbine flowmeter.
