Influence of V-cone flow meter service conditions deviating from the standard

Abstract: The influence information of V-cone flow meter using conditions deviating from the standard is provided by excellent flow meter and flow meter manufacturers and quotation manufacturers. Sometimes it is difficult to ensure that the field parameters are always within the specification range. The outflow coefficient of the cone flowmeter is related to parameters such as diameter ratio and Reynolds number Red. So when these parameters deviate, additional uncertainty will occur. The following will give you the main introduction. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the impact of the V-cone flowmeter's use conditions deviating from the standard. Sometimes it is difficult to ensure that the field parameters are always within the specification range, and the ratio of the outflow coefficient of the cone flowmeter to the diameterβIt is related to parameters such as Reynolds number Red. So when these parameters deviate, additional uncertainty will occur. The following will mainly introduce the main ways for V-cone flowmeter to deviate from the specification parameters: 1βIn fact, everyone mayβI know more or less, let me introduce to you firstβthe meaning of the value. It is the ratio of the diameter of the throttling member to the inner diameter of the pipe. In the final analysis, the V-cone flowmeter is derived from the combination of the annular orifice plate and the classic Venturi tube, so the V-cone also combines the advantages and can measure dirty media with low pressure loss. According to the classical Venturi theory, the actualβshould be controlled within 0.75, whenβWhen the value is greater than 0.75 due to improper design, the dispersion of the outflow coefficient is too large, and the uncertainty of the outflow coefficient is more than doubled. 2 Reynolds number Red affects the V-cone flowmeter due to its special structure compared to the standard throttling device. The lower limit of the Reynolds number has been greatly improved, but it is not very limited. When the Reynolds number is lowered indefinitely, the outflow coefficient of the V-cone flowmeter decreases with the decrease of the Reynolds number, while its Uncertainty will increase. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
