V-coneflow meter, also known as;V-cone flowmeterV-shaped cone flowmeter; Cone flowmeter; Cone flowmeter; Internal cone flowmeter; Internal cone flowmeter, integrated V-cone flowmeter. V-cone flowmeter is a differential pressure flowmeter, and its successful development is a qualitative leap in differential pressure flow measurement.

1、 Structure and advantages
The V-cone flowmeter is a new type of differential pressure flow measurement device that uses a pointed cone installed coaxially in the measuring tube as the throttling element. It is a new throttling device based on the principle of Venturi tube measurement and integrates the advantages of classical Venturi tube, annular orifice plate, and wear-resistant orifice plate. The table body is divided into: connection type table body, pressure type table body, and pipeline welding type table body. 1. The requirements for the upstream and downstream straight pipe sections are relatively short: the length of the upstream straight pipe section is 0-3d, and the length of the downstream straight pipe section is 0-1d. 2. Accuracy level: 0.2 level, 0.5 level; The repeatability is 0.1%; The range ratio can reach 15:1. 3. Resistant to dirt and minimal pressure damage. 4. Has the ability to regulate flow and mix fluids. 5. Wide measurement range (small to large flow), suitable for pipe diameters ranging from DN15 to DN3000.
2、 Technical parameters
1. High stability: better than 0.1% fs/year; 2. High static pressure: 40mpa; 3. Continuous work for 5 years without the need for adjustment; 4. The influence of temperature and static pressure can be ignored; 5. Resistant to high overvoltage.
3、 Selection of required parameters
1. The diameter of the pipeline; 2. Type of medium; 3. Medium temperature; 4. The working pressure of the medium (maximum pressure, minimum pressure, normal pressure); 5. The working flow rate of the tested medium (maximum flow rate, minimum flow rate, normal flow rate); 6. Medium viscosity
