The smaller the diameter, the more difficult it is to manufacture a V-shaped cone flowmeter

For the flow meter industry, DN25 to DN500 are all conventional sizes, so its manufacturing technology is relatively mature and stable. For flowmeters outside this range, whether smaller or larger, they are more expensive and more difficult to manufacture. The reasons are as follows:

1. Size and accuracy: Smaller diameter V-cone flow meters require higher manufacturing accuracy, because any small deviation or manufacturing error may have a significant impact on the measurement accuracy. Small-diameter V-shaped cones require more precise processing and manufacturing to ensure stable and reliable performance.

2. Fluid Dynamics: Smaller diameter V-shaped cones face more challenges in fluid dynamics. Due to higher flow rates, the fluid may be more prone to turbulence, which may induce measurement inaccuracies. Therefore, more sophisticated design and manufacturing are required to reduce the effects of turbulence.

3. Installation and maintenance: Small-diameter V-shaped cones may require smaller installation space, which may increase the difficulty of installation. Additionally, maintaining and cleaning small-bore V-cones can be more difficult because of limited work space.

4. Materials and durability: Small-diameter V-shaped cones may require higher strength and corrosion-resistant materials to cope with high flow rates and high pressure requirements, which may increase manufacturing costs and difficulty .

Because manufacturing a small-diameter V-shaped cone flowmeter requires more engineering and refinement of the manufacturing process to ensure stable and reliable performance, the difficulty and cost of manufacturing increase.
