V-cone flowmeter
Product Detail



V cone flowmeter

The successful development of V - cone sensor is a qualitative leap in differential pressure flow measurement. It USES a special streamlined conical body installed in the center line of the pipeline to throttle. The positive pressure PH is taken in the high-speed steady flow area in front of the cone and the negative pressure PL is taken in the central steady flow area at the end of the cone. Within the range of Reynolds number 8 103 ~ 5 106, the flow is proportional to the square root of the differential pressure.


1. Fluid name

2. Inner and outer diameter of pipe (mm)

3. Choose the type of v-cone flow sensor

4. Calibration flow units (kg/h, t/h, m3/h, Nm3/h)

5. Common flow, minimum flow and maximum flow

A. at work

B. In the standard state (the standard state of flow shall be stated when the medium is a gas)

6. Working pressure (MPa)

7, fluid temperature (℃) : maximum, minimum, commonly used temperature

8. Fluid density (kg/m3)

A. at work

B. In the standard state (the state of density value should be stated when the medium is a gas)

9. Fluid viscosity (Pa·s)

10. Relative humidity

11. Gas composition: volume percentage (for two or more mixed gases)

12. Installation of sensors

Level of a.

B. bottom-up

13. Pipe flange

A. According to the flange standard specification, code name is to provide the flange standard and model

B. Party b shall provide the design drawings of the flange


· measuring water and water vapor shall be provided (1), (2), (4), (5), (6), (7), (12)

· general gas measurement shall be provided (1) ~ (13)

, measuring the general solution and oil shall provide (1), (2), (4), (5), (6), (7), (8), (9), (12), (13)

· each item of data must be filled in a specific value of process design. Please do not fill in a range of about how much.


1. Low installation requirements: the front 0-3d straight pipe segment, and the back 0-1d straight pipe segment.

2. Specific width of range: it is usually 10:1, and the most suitable parameter can be 50:1

3, small pressure loss: the same value, pressure loss is hole plate 1/3 ~ 1/5

4, wear resistance: after the streamline conical body throttling, the surface of the conical body produces a vacuum layer effect, making the conical body not easy to wear

5. Non-clogging and non-adhesion: the cone-shaped thorough purge design avoids residues, condensate or particles in the fluid

6, good long-term stability: value can be long-term change, and ensure long-term accurate measurement

7. High precision: 0.5%

8. Good repeatability: better than 0.1%

9. Stable signal: "signal fluctuation" is 1/10 of the orifice plate

Wide range of values: the unique geometry of the v-cone flow sensor allows for a wide range of values

11. Wide range of pipe diameter: from 15mm to 2000mm

12, measurable, high temperature and high pressure medium: the highest working temperature 850 ℃, the maximum pressure of 40 mpa.

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

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