Standard throttling device for tower flowmeter used in Suchuan supply pipeline

Differential pressure typeStandard throttling device for pipeline tower flowmeterIt is a gradual contraction of the pipeline edge wall caused by the contraction of the variable fluid at the center of the pipeline. This is achieved by using a tower shaped body (throttling element) installed coaxially in the pipeline to force the fluid to gradually contract from the center to the inner wall of the pipeline and flow through the tower. The fluid flow rate is obtained by measuring the pressure difference before and after the tower.

Standard throttling device for tower flowmeter used in Suchuan supply pipelineFeatures:

1. Has good accuracy (≤ 0.5%) and repeatability (≤ 0.1%).
2. Has a wide range ratio (10:1-15:1)
3. The self rectification function only requires a very short straight pipe section (front 1-3D and back 0-1D).
4. Self cleaning function, capable of detecting dirty and easily scaling fluids, suitable for media with high impurities such as blast furnace gas.
5. Self protection function, key parts of the throttle component do not wear out, and can maintain long-term stable operation.
6. Resistant to high temperature, high pressure, corrosion, and vibration.
7. The types of measurable fluids are very wide (liquid, gas, steam), and the flow measurement range is wide (small flow to large flow), suitable for pipelines ranging from DN15 to DN3000.
8. The structure design of the flowmeter is a fluid sweep type structure, which cannot intercept any gas, liquid or solid impurities carried in the fluid. It is very suitable for flow measurement of dirty fluids, such as coke oven gas, wet gas, etc
9. No movable parts
10. When fluid flows through an inner cone with a special profile, a boundary layer is formed around it and guides the fluid away from the edge of the cone tail, thereby reducing its likelihood of wear.
11. Measuring steam and hot water at the heat exchange station does not require a straight pipe section. Due to the small space of the heat exchange station, selecting a general flow meter requires a long straight pipe section, which affects the operating accuracy. It is used to measure blast furnace gas and has a self-cleaning effect. The pressure pipe is not easily blocked.
