V-Cone Flowmeter Principle

The tower (V-shaped cone) flow meter has the same principle as other differential pressure flow meters, and is also a throttled differential pressure flow meter. The appearance of the tower (V-shaped cone) broke the structure pattern that has been inherited for nearly a century, making the throttled differential pressure instrument a "qualitative leap". The major breakthrough of the tower-shaped (V-cone) flowmeter lies in "variable fluid shrinkage in the center of the pipe center to the side wall shrinkage". In recent years, based on the unique advantages of the original V-shaped cone, we have also developed a tower-shaped flow meter with a number of anti-blocking patents from our company. The flow meter uses a number of patented technologies such as multi-hole pressure extraction, ring chamber pressure extraction, and integrated installation. Widely used in the measurement of particularly dirty fluids (such as: coke oven gas, blast furnace gas, etc. in steel plants).

※ It has good accuracy (≤0.5%) and repeatability (≤0.1%).

※ It has a wide range ratio (10 ﹕ 1 ~ 15 ﹕ 1).

※ It has the function of rectifying the fluid, so only very short straight pipe sections are required (front 1 to 3D and back 0 to 1D).

※ With self-cleaning function, it can measure dirty and fouling fluid.

※ The key parts of the throttle are not worn, so they can work stably for a long time.

Technical characteristics of V-cone flowmeter : 1. Low installation requirements: straight 0 ~ 3D straight pipes, and rear 0 ~ 1D straight pipe sections;

2. Wide range ratio: usually 10: 1, choosing the right parameter can achieve a maximum of 50: 1;

3. Small pressure loss: the same β value, the pressure loss is 1/3 ~ 1/5 of the orifice plate;

4. Abrasion resistance: After the streamlined cone is throttled, a vacuum layer effect is generated on the surface of the cone, making the cone difficult to wear;

5. Non-clogging and non-adhesion: The cone-shaped thorough purging design avoids the retention of residues, condensates or particles in the fluid;

6, long-term stability is good: β value can be unchanged for a long time, and ensure long-term accurate measurement;

7, high precision: 0.5 level;

8. Good repeatability: better than 0.1%;

9. Signal stability: "Signal fluctuation" is 1/10 of the orifice plate;

10. Wide β value range: The unique geometry of the V-cone flow sensor allows a wide range of β values;

11. Wide caliber range: DN25 ~ DN2000;

12. Measurable high-temperature and high-pressure media: working temperature up to 850 ℃, maximum pressure 40MPa;

13. Measurable dirty media (coke oven gas, blast furnace gas, raw oil, residue oil, etc.);

14. Measurable gas-liquid two-phase medium (moisture, condensate, etc.);
