Product overview:

JKLV series V-cone Flowmeter is a differential pressure flowmeter. Its successful development is a qualitative leap in differential pressure flow measurement. It uses the throttling effect of V cone in the flow field to measure the flow rate by detecting the pressure difference between upstream and downstream. Compared with the common throttling parts, it changes the throttling layout from the central orifice to the annular throttling. Practical application shows that V-cone Flowmeter has the advantages of high long-term accuracy, good stability, small limitation by installation conditions, wear resistance, wide measurement range, small pressure loss, and suitable for dirty media. Moreover, the V-cone itself, as a rectifier of flow field, has become an excellent new flowmeter with unique performance. The V-cone Flowmeter composed of V-cone sensor and differential pressure transmitter can accurately measure the flow rate of various media in a wide range of Reynolds number (8 × 103 ≤ re ≤ 5 × 107).

Product features:

1. High precision: ± 0.5%;

2. Good repeatability: 0.1%;

3. Wide caliber range: DN 15-dn2000;

4. It can measure the flow rate of high pressure and high temperature medium: 0-40 MPa, - 40 ~ 850 ℃;

5. The installation of straight pipe is short: 0-3d upstream and 0-1D downstream;

6. Small permanent pressure loss: only 1 / 3 ~ 1 / 2 of orifice plate;

7. Stable output differential pressure: small fluctuation at negative pressure end of V cone tail;

8. Low measurement limit: the minimum output differential pressure is 25Pa;

9. Range ratio: 1:10;

10. It has self rectification function: it can measure mixed phase flow;

11. With self cleaning function: no debris retention, suitable for flow measurement of dirty media;

12. Good long-term stability: the fluid is gradually contracted to the inner side wall of the pipe, and the wear of V-cone is small;

13. Wear resistance, no need of repeated calibration: special streamline structure makes the β side of V-cone not easy to be worn, so it has good stability and long service life, and the V-cone sensor does not need repeated calibration;

14. Anti clogging patented technology, no blockage, no adhesion, can measure the flow of dirty media, such as blast furnace gas, coke oven gas, etc.
