Selection of Differential Pressure Value in Design and Calculation of V Cone Flow Meter and Orifice Flow Meter

Abstract: The selection information of the differential pressure value during the design and calculation of the V-cone flow meter and the orifice flow meter is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. Keyword: V-cone flowmeter orifice flowmeter time differential pressure value production throttling device manufacturers know that when calculating the opening diameter of the orifice plate flowmeter and V-cone flowmeter and other throttling devices according to the field parameters, it will involve Such a problem is differential pressure transmission. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the selection article for the design and calculation of the differential pressure value of the V-cone flowmeter and the orifice flowmeter. Keyword: V-cone flowmeter orifice flowmeter time differential pressure value production throttling device manufacturers know that when calculating the opening diameter of the orifice plate flowmeter and V-cone flowmeter and other throttling devices according to the field parameters, it will involve Such a question is how to select the maximum differential pressure value of the differential pressure transmitter? How to choose the differential pressure value and how big should it be? It is related to many factors, such as: uncertainty, front and rear straight pipe sections, etc. Therefore, when calculating the opening diameter of the orifice flowmeter and V-cone flowmeter, you must not blindly select a large differential pressure, but comprehensively consider some relevant factors. 1. When the differential pressure value is large, the minimum straight pipe section required can be shorter. For this feature, for the orifice plate flowmeter, considering various economic factors, the opening value with the largest differential pressure should be selected; and the V-cone The flowmeter is relatively better. If the on-site fluid is Newtonian fluid, the requirements for the straight pipe section of the V-cone flowmeter itself are relatively low. Even if it is shorter, in comparison, it does not exist. 2. The differential pressure value is large. hour,βThe smaller the value, the smaller the recommended minimum Reynolds number. In this case, the actual Reynolds number may be much larger than the recommended Reynolds number, so the flow coefficient tends to be stable and the measurement accuracy is improved. 3. For the differential pressure transmitter, a larger differential pressure is more stable than a small differential pressure. 4. The above descriptions are basically all the advantages of selecting a large differential pressure, but in many cases, when it develops to a certain extent, it will definitely bring certain disadvantages. Those who are familiar with the processing technology of orifice flowmeter and V-cone flowmeter should know that when the differential pressure is too large, the direct consequence is that the opening becomes small, and the pressure loss is relatively large. The plate flowmeter has a large pressure loss. If this is added, the cost due to this pressure loss is considerable for the entire process system; compared with the V-cone flowmeter, it is slightly moderate. Therefore, in our usual production process, we cannot blindly suggest that our users choose a large differential pressure value, but we must be truly responsible for the customer and the enterprise. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
