Overview

The V-cone flowmeter $r $n 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 detecting the upstream and downstream pressure difference. Compared with ordinary throttling components, it has changed the throttling layout from central orifice throttling to annular throttling.

Product Details

integrationV-cone flow meterA 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 detecting the upstream and downstream pressure difference. Compared with ordinary throttling components, it has changed the throttling layout from central orifice throttling to annular throttling. Practical use has proven that compared with other flow meters, it has the advantages of high accuracy, good stability, limited installation conditions, wear resistance, wide measurement range, low pressure loss, and suitability for contaminated media. Moreover, the V-cone itself serves as a rectifier for the flow field, making it an excellent new type of flowmeter with exceptional performance. Composed of a V-cone sensor and a differential pressure transmitter, it can accurately measure the flow rate of various media within a wide Reynolds number range (8 × 103 ≤ Re ≤ 5 × 107).

Main technical parameters
·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)
·Repeatability: 0.1%
·Work pressure: 0-40MPa (with multiple pressure levels to choose from)
·Working temperature: -40 to 850 ° C
·Environmental temperature: -40 to 65 ° C
·Installation requirements for straight pipe section: front 0-3D straight pipe, rear 0-1D straight pipe section
·Range width ratio: usually 10:1, selecting appropriate parameters can achieve 50:1
·Small pressure loss: For the same β value, the pressure loss is 1/3 to 1/5 of the orifice plate
·Caliber ranging from DN25 to DN2000

V-cone flow meterTechnical features:
1. Low installation requirements: front 0-3D straight pipe, rear 0-1D straight pipe section;
2. Range width ratio: usually 10:1, selecting appropriate parameters 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 * blowing design avoids the retention of residues, condensates, or particles in the fluid;
6. Good stability: The β value can remain unchanged and ensure 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 range of beta values: The 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 850 ℃, high 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.);
