Name: V-cone flowmeter
Manufacturer: Shanghai Automation Instrumentation Co., Ltd.
Application: SKC-1010 V-cone flowmeter, V and V cone flowmeter, v-cone flowmeter, V cone flowmeter and cone flowmeter, inner cone flowmeter, inner cone flowmeter, the integration of V cone flowmeter, V cone flowmeter, English name is V - cone flowmeter. V cone flowmeter is a differential pressure flowmeter developed in the 1980s. Its development success is a qualitative leap of differential pressure flow measurement.
Working principle is to be full of pipeline fluid, flowing through the pipe orifice flow, velocity of flow in the formation of local contraction flow orifice throttling, accelerated to flow, static pressure is reduced, so the standard orifice plate before and after the pressure drop is produced or pressure differential, medium, the greater the flow of traffic, the flow before and after the orifice of the greater the pressure difference, so can be measured by a pressure difference to measure the size of the fluid flow. This method is based on the principle of flow continuity equation (mass conservation law) and Bernoulli's equation (energy conservation law).
High accuracy: plus or minus 0.075%.
High stability: better than 0.1%fs/ year.
High static pressure: 40mpa.
No adjustment is required for the continuous work for 5 years.
The influence of temperature and static pressure can be ignored.
The pressure is high.
1. Good accuracy (no more than 0. 5%) and repeatability (less than or equal to 0. 1%).
2. Wide range ratio (10:1 ~ 15:1)
3. Self-rectification function only requires extremely short straight pipe sections (first 1 ~ 3D, 0 ~ 1D).
4. Self-cleaning function can be used to measure dirty and easy scaling fluid, suitable for the medium with more impurities such as blast furnace gas.
5. Self-protection function, the key parts of the throttle body are not worn out, and can maintain long-term and stable work.
6. High temperature resistance, high pressure, corrosion resistance, no fear of vibration.
7. The types of the detectable fluid are very extensive (liquid, gas, steam), the flow measurement range is wide (small flow ~ large flow), and the suitable pipeline is DN15 ~ DN3000.
8, the structure design is a fluid sweep type structure of the flow meter, impossible to intercept any entrained in the flow of gas, liquid or solid waste, very suitable for smudgy fluid flow measurement, such as coke oven gas and wet gas, etc
9. No moving parts.
10. When the fluid flows through the inner cone of the filling, the boundary layer is formed around it and the fluid is removed from the edge of the tail of the cone, thereby reducing the possibility of wear.
11. Measure the steam and hot water at the heat exchange station without direct pipe section. Due to the small space of the heat transfer station, the general flow meter is selected to require the long straight pipe section, which affects the operation precision. It is used in the measurement of blast furnace gas, which has the self-cleaning effect, and the pressure pipe is not easily blocked.
