The fluid flows through a pipe at a certain pressure and at a certain temperature, and when it passes through a turn, the fluid will make a corresponding circular rotary motion. According to the fluid forced swirling theory, the fluid in the pipe makes a circular motion similar to the solid in the space state, so the fluid will inevitably produce the inertia centrifugal force, the size of the centrifugal force and the fluid flow velocity, the fluid density and the circular motion Curvature radius (that is, the radius of curvature of the elbow flowmeter sensor) and other factors. Since the radius of curvature of the elbow flowmeter sensor is known, the density of the fluid flowing through the elbow sensor can be accurately obtained by measuring the temperature, pressure, and other parameters of the fluid using a computer of the host computer. Therefore, the fluid density is generated on the elbow sensor. The size of the centrifugal force is simply a function of the fluid flow rate. As long as the size of the centrifugal force is measured, the flow rate of the fluid in the pipe can be measured. The flow rate is multiplied by the cross-sectional area of ​​the pipe and the density of the fluid. The flow rate of the fluid can be calculated and determined. The calculations are as follows: Formula 1 gives the functional expression of the average flow rate and differential pressure value of the flow through the elbow V=a[(P1-P2)/ρ]β--------1 Where: V - the average flow rate of the fluid; a --- comprehensive flow coefficient, a = f (bending ratio of bends, Reynolds number, dynamic viscosity of the medium, roughness of the pipeline, etc.), and the influence of the ratio of the bend diameter is the most important: P1-P2----- pressure difference between the inside and outside of the bend; Fluid density; ----index; Calculate the average flow velocity V to obtain the functional expression of the calculated flow: Q=S*V*ρ-----------2 In the formula: S----the cross-sectional area of ​​the elbow; V - the average flow rate of the fluid; Application scope of elbow flowmeter 1.
