The principle of the calculation formula of the elbow flow meter

Abstract: The principle information of the calculation formula of the elbow flowmeter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Like traditional orifice flowmeters, elbow flowmeters belong to the category of differential pressure flowmeters, but the way of differential pressure generated by elbow flowmeters is different from that of orifice flowmeters. The orifice plate uses the scaling principle of the fluid to generate differential pressure, and the elbow sensor is used. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the article on the principle of the calculation formula of the elbow flowmeter. Like traditional orifice flowmeters, elbow flowmeters belong to the category of differential pressure flowmeters, but the way of differential pressure generated by elbow flowmeters is different from that of orifice flowmeters. The orifice plate uses the scaling principle of the fluid to generate differential pressure, while the elbow sensor uses the inertial principle of the fluid to generate differential pressure. When the fluid passes through the elbow, due to the constraint of the elbow, the fluid is forced to make a similar circular motion, and the centrifugal force generated by the fluid during the circular motion acts on the inner and outer sides of the elbow, causing the inner and outer sides of the elbow sensor to generate a pressure difference. The size of the pressure difference is related to the density of the fluid, the average flow rate, the radius of curvature of the pipe, and the inner diameter of the pipe. is the inner diameter of the elbow; R/D is the radius of curvature of the center of the elbow; ΔP is the differential pressure value generated when the fluid passes through the elbow sensor of the elbow flowmeter;ρis the density of the medium. The flow rate of the fluid in the pipeline: in the formula, S is the internal cross-sectional area of ​​the pipeline;αis the flow coefficient. It can be seen from the above that as long as the pressure difference is accurately measured, and the necessary temperature compensation is performed while taking into account the influence of temperature and pressure on the density of the medium, the elbow flowmeter can accurately measure the flow rate of the medium. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
