XG-V Series V-notch Flow Meters

The XG-V Series V-notch Flow Meters are differential pressure instrument that measures fluid flow inside a pipe based on the laws of conservation of mass and energy. It innovatively utilizes a V-shaped cone suspended at the center of the pipeline as a throttling element, which has the unique advantages of self-rectification and self-cleaning. It is a new type of instrument with a wide range of applications.

Product Features:
1. The self-cleaning function of the XG-V cone flowmeter slows down the flow velocity at the center of the pipeline and accelerates the flow velocity near the pipe wall when the fluid passes through the V-shaped cone, making it difficult for dirt to deposit on the throttling element, which is beneficial for accurate and stable measurement.
2. The XG-V cone flowmeter has a self-rectification function. The V-shaped cone, which can slow down the flow velocity at the center of the pipeline and accelerate the flow velocity near the pipe wall, effectively improves the distribution of fluid flow velocity, achieves self-rectification, and greatly shortens the length of the front and rear straight pipes. As long as it reaches the front 0-3DN and rear 0-1DN, it can be used.
3. Good wear resistance, good long-term stability, and high measurement repeatability.
4. The special structure has low pressure loss, with pressure loss ranging from 1/3 to 1/5 of the orifice plate. The range ratio is 10:1 (special up to 30:1).
5. The special structure is suitable for measuring low static pressure and low flow rate.
6. Due to the unique structure of the conical flowmeter, it is often used as a mixer in many cases.
7. Suitable for working temperatures up to 850 ° C and pressures up to 42MPa. If special materials are used, the range is even higher.
8. For the convenience of users, our company's XG-V cone flowmeter has both integrated and split structures.
9. Our company's patented plug-in XG-V cone flowmeter system solves the problem of the high cost of using V-cone sensors for large diameters, retains the advantages of V-cone measurement, greatly expands the application field of V-cone flowmeters, and solves the problem of small differential pressure in large-diameter pipelines, which makes measurement inconvenient. Has good economy, timeliness, and stability.
10. The intelligent integrated V-cone flowmeter adopts advanced circuit design, powerful functions, low power consumption, a large-screen LCD for flow information, and advanced internal memory to ensure data security.
11. The integrated V-cone flowmeter system can be powered by batteries and external 24VDC, outputs 4-20 mA and pulse signals, and has the HART protocol.          

Main selling points:
1. Short straight pipe section requirement: Equipped with flow field rectification effect, only 0-3D upstream and 0-1D downstream straight pipe sections are needed. It can also be installed and used for on-site renovation and narrow pipeline spaces, reducing construction costs.
2. Suitable for dirty and complex media: The annular throttling structure has a self-blowing and self-cleaning effect, which makes it difficult for dust to accumulate and block. It can measure gas, liquid, and steam media that contain impurities, are prone to scaling, and have high viscosity.
3. Stable and reliable measurement: No moving parts, good repeatability, wear resistance, small long-term accuracy attenuation, stable measurement under high and low flow rate conditions, wide range ratio.
4. Small pressure loss: Compared with orifice plate throttling devices, it has lower pressure loss, saves system energy consumption, and is suitable for large pipe diameters and continuous uninterrupted production conditions.
