As a new type of differential pressure flow meter, the V-cone flowmeter has seen an increasing use over the years, showing a trend toward replacing traditional throttling devices. However, it still has certain limitations when used in high-pressure applications. Its discharge coefficient is related to parameters such as the diameter ratio β and the Reynolds number Red. In field applications, these parameters deviate from their nominal values, which results in additional uncertainty for the flow meter; I will give you a brief introduction to this below. Effect of the Reynolds number Red — Due to its special structure, the V-cone flow meter allows for a significantly lower minimum Reynolds number compared to standard throttling devices, though it is not at the absolute lowest level. As the Reynolds number decreases without limit, the discharge coefficient of the V-cone flow meter decreases as well with the reduction in Reynolds number, while its uncertainty increases. The influence of the β value — First, let me explain what the β value means; it is the ratio of the diameter of the throttling element to the inner diameter of the pipe. In fact, the V-cone flow meter is derived from a combination of an annular orifice plate and a conventional Venturi tube. Therefore, the V-cone also incorporates their advantages, enabling it to measure dirty media with low pressure loss. According to the classical Venturi theory, the actual value of β should be kept below 0.75; when this value exceeds 0.75 due to improper design, the dispersion of the discharge coefficients increases, and the uncertainty of these coefficients more than doubles. Practice has shown that, compared with other flow meters, the V-cone flow meter offers advantages such as high long-term accuracy and good stability, minimal constraints due to installation conditions, wear resistance, a wide measurement range, low pressure loss, and suitability for dirty media.
