Product Overview:

V-cone flowmeter, also known as V-cone flowmeter; V-shaped cone flowmeter; Cone flowmeter; Cone flowmeter; Internal cone flowmeter; Internal cone flowmeter, integrated V-cone flowmeter. V-cone flowmeter is a differential pressure instrument that measures fluid flow inside a pipe based on the laws of conservation of mass and energy. It utilizes the throttling effect generated by the V-cone in the flow field to measure the flow rate by monitoring the upstream and downstream pressure difference. Compared with ordinary throttling components, it has changed the throttling layout from a middle orifice throttling to a circular throttling. Practical use has proven that compared with other flow meters, V-cone flowmeters have the advantages of high long-term accuracy, good stability, limited installation conditions, wear resistance, wide measurement range, low pressure loss, and suitability for contaminated media. Moreover, the V-cone itself, as a rectifier for the flow field, has become an excellent new type of flowmeter with unique performance. The V-cone flowmeter, composed of a V-cone sensor and a differential pressure transmitter, can accurately measure the flow rate of various media within a wide Reynolds number range (8 × 103 ≤ Re ≤ 5 × 107).

Product Features:

1. Low installation requirements: front 0-3D straight pipe, rear 0-1D straight pipe section;

2. Range width ratio: usually 10:1, selecting the appropriate parameter upper limit can achieve 50:1;

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

4. Wear resistance: After throttling the streamlined cone, a vacuum layer effect is generated on the surface of the cone, making it less prone to wear;

5. No blockage, no adhesion: The conical thorough blowing design avoids the retention of residues, condensates, or particles in the fluid;

6. Good long-term stability: The β value can remain unchanged for a long time and ensure accurate measurement over the long term;

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 range of beta values: The unique geometric shape of the V-cone flow sensor allows for a wide range of beta values;

11. Wide caliber range: DN25 to DN2000;

12. Measurable high temperature and high pressure medium: working temperature upper limit 850 ℃, upper limit pressure 40MPa;

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

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