1. Scope of application of V-cone flowmeter

1. nominal diameter: 15mm ≤ DN ≤ 1800mm

2. nominal pressure: PN ≤ 40MPa

3. Reynolds number range: 5 × 10 ≤ ReD ≤ 10

4. accuracy level: 0.5 level, 1 level

5. straight pipe length: front 1-3D, back 0-1D

6. applicable media: various media such as gas, liquid, steam

7. aperture ratio: β=0.3-0.75

2、 Wide caliber range: DN25 to DN2000; 1

3、 Accuracy level: 0.5 level (differential pressure flow transmitter accuracy should be higher than 0.2 level, including 0.2 level), (β: 0.45-0.85, when β<0.55, range ratio 4:1, accuracy level: ≤ 0.30)

2. Technical indicators of V-cone flowmeter

▲ High accuracy: ± 0.075% ▲ High stability: better than 0.1% fs/year ▲ High static pressure: 40mpa ▲ Continuous operation for 5 years without calibration ▲ Temperature and static pressure effects can be ignored ▲ Anti four hand high overpressure

1. Good accuracy (≤ 0.5%) and repeatability (≤ 0.1%).

2、 It has a wide range ratio (10:1-15:1)

3. It has self rectification function and only requires a very short straight pipe section (front 1-3D and back 0-1D).

4、 Self cleaning function, capable of detecting dirty and easily scaling fluids, suitable for media with high impurities such as blast furnace gas.

5、 Self protection function, key parts of the throttle component do not wear out, and can maintain long-term stable operation.

6、 Resistant to high temperature, high pressure, corrosi

7、 The types of measurable fluids are very wide (liquid, gas, steam), and the flow measurement range is wide (small flow to large flow), suitable for pipelines ranging from DN15 to DN3000.

8、 The structure design of the flowmeter is a fluid sweep type structure, which cannot intercept any gas, liquid or solid pollutants carried in the fluid. Non state flow meters are often suitable for flow measurement of dirty fluids, such as coke oven gas, wet gas, etc. 9. No movable parts 10. When the fluid flows through an inner cone with a special profile, a boundary layer will be formed around it and the fluid will be guided away from the edge of the cone tail, thereby reducing the possibility of wear. 1

1、 Measure steam and hot water at the heat exchange station without the need for a straight sail or buried pipe section. Due to the small space of the heat exchange station, selecting a general flow meter requires a long straight pipe section, which affects the operating accuracy. It is used to measure blast furnace gas and has a self-cleaning effect. The pressure pipe is not easily blocked.

3. What is a V-cone flowmeter? What are the advantages? Hello, KNKE, a manufacturer of V-cone flow meters imported from the United States, is pleased to answer your question. The V-cone flowmeter is a high-precision and stable flow measurement device that uses a unique V-shaped cone to change the flow rate of fluids, suitable for measuring the flow rate of various liquids or gases. The working principle of a V-cone flowmeter is that when the fluid passes through the V-cone flowmeter, the shape of the cone megameter will change, and according to the flow rate of the fluid, the shape of the cone will
