What are the measurement ranges of vortex flowmeters?

1、 Vortex flowmeter is a flowmeter based on the Karman vortex principle for measurement. It can measure liquids and gases, and is also very economical. The diameter is generally DN10-- DN1000. With temperature and pressure compensation, it can accurately measure gas or steam flow, and has a wide range of applications;

2、 Vortex flowmeter can only measure volumetric flow rate, usually in m3/h (cubic meters per hour), with instantaneous flow display and cumulative flow display;

3、 The measurement range corresponding to electromagnetic flow meters of different diameters is: liquid measurement: (unit: m3/h): DN15

1.2-6; DN20

1.5---10； DN25：2---16； DN32

1.8---20； DN40：2.5---25； DN50：3.5---40； DN65：7.5---70； DN80：12---130； DN100：18---160； ..... Gas measurement: (unit: m3/h): DN15:4--28; DN20：6---40； DN25：8---50； DN32：15---150； DN40：18---180； DN50：25---480； DN65：50---500； DN80：80---800； DN100：120---1200； .....

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 calcu

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.
