Effects of V-Cone Flow Meter Deviation from Standard

Abstract: The influence information of V-cone flow meter deviating from the standard is provided by the excellent flow meter and flow meter manufacturer and quotation manufacturer. The outflow coefficient of V-cone flowmeter is related to parameters such as diameter ratio and Reynolds number Red, and sometimes it is difficult to ensure that the field parameters are always within the standard range, so when these parameters deviate, additional uncertainty will be generated. The main ones are given below. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the impact of V-cone flowmeters deviating from the standard. Outflow Coefficient to Diameter Ratio of V Cone FlowmeterβIt is related to parameters such as Reynolds number Red, and it is sometimes difficult to ensure that the field parameters are always within the standard range, so when these parameters deviate from the phenomenon, additional uncertainty will be generated. The following will mainly introduce the main ways for the V-cone flowmeter to deviate from the standard parameters: 1.βThe impact of value will be introduced to you first.βThe meaning of value, in fact, you may be rightβMore or less, it is the ratio of the diameter of the throttling member to the inner diameter of the pipe. After all, the V-cone flowmeter is derived from the combination of the annular orifice plate and the classic Venturi tube. So V-cones also combine their advantages, being able to 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. Influence of Reynolds number Red Due to its special structure, the V-cone flowmeter has a great improvement in the lower limit of Reynolds number compared to the standard throttle device, but it is not very limiting. When the Reynolds number decreases indefinitely, the outflow coefficient of the V-cone flowmeter decreases with the decrease of the Reynolds number, and its uncertainty increases. As a new type of differential pressure flow meter, the use of V-cone flowmeter has been increasing year by year in recent years, and it has a tendency to replace standard throttling devices. However, it is still somewhat limited in high-pressure applications because the cone The structure of the negative pressure pipe will fall off when it is subjected to high pressure, so our production enterprises cannot blindly produce, and must comply with the on-site parameters. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Effects of V-Cone Flow Meter Deviation from Standard'
