1. Structure of V-cone flowmeter
V-cone flowmeter is a new type of differential pressure flow measurement device that uses a pointed cone installed coaxially in the measuring tube as the throttling element. It is based on the principle of Venturi tube measurement and integrates the advantages of classic Venturi tube, annular orifice plate and wear-resistant orifice plate. Due to its special structural form, the V-cone flowmeter has the following characteristics:
1. The upstream and downstream straight pipe sections are required to be relatively short: the length of the upstream straight pipe section is 0-3d, and the length of the downstream straight pipe section is 0-1d.
2. Accuracy: ± 0.5%; The repeatability is 0.1%; The range ratio reaches 15:1.
3. Anti dirt and low pressure loss.
4. It has the function of flow regulation and mixing of fluids.
5. Easy to install, it is an ideal leak resistant flowmeter for technical transformation; 6. Maintenance free disassembly or minimal maintenance workload.
2. Technical specifications of V-cone flowmeter
▲ High precision: ± 0.075% ▲ High stability: better than 0.1% fs/year ▲ High static pressure: 40mpa ▲ Continuous operation for 5 years without calibration ▲ Negligible temperature and static pressure effects ▲ Resistance to high overpressure in all directions
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 b
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, corrosion, and vibration.
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.
