Introduction to the principle of flow meter scale power coefficient and related formula

Abstract: introduction to the principle of flow meter scale powerful and related formula coefficient of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. When the fluid flows through the power flow meter probe, a high pressure generated in the front of its distribution area, hydrostatic pressure slightly higher than the area of high pressure pipe. According to the principle of Bernoulli equation, to speed up the speed when the fluid flows through the probe, the probe at the back of the produce a low pressure points. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the introduction to the principle of flow meter scale powerful coefficient article details and related formula. When the fluid flows through the power flow meter probe, a high pressure generated in the front of its distribution area, hydrostatic pressure slightly higher than the area of high pressure pipe. According to the principle of Bernoulli equation, to speed up the speed when the fluid flows through the probe, the probe at the back of the produce a low pressure area, the pressure is slightly lower than area of low pressure pipe of the static pressure. Fluid from the power meter probe through the vacuum on the probe at the back of the part, and appear on both sides of the probe, power average flow sensor can accurately detect the flowmeter produced by the average speed of fluid differential pressure on average. Power meter and other differential pressure flowmeter follow Bernoulli equation qV = KCΔ p ( 1) QV&mdash type; — — The volume of fluid flow; K— — — Flow coefficient; C— — — Flow rate constant ( Constant) ; Δ p— — — Differential pressure generator differential pressure. C is constant, to determine the qV, K and must be determined & Delta; p。 Power flow meter according to the theory of aerodynamics, fluid mechanics, the boundary layer theory and the actual fluid test data, after the exploration into 5 a, pioneering established mathematical analysis model of power flow probe, K. K = 1 / ( 1 / ( 1 - Cbβ V) +C] ( 2) Cb&mdash type; — — Boundary layer coefficient; β V— — — Blocking the coefficient. This is on the specific application of Bernoulli equation theory. 1) The accuracy of the K + 0. The flow of 5%, by the world famous independent laboratory confirmed by comprehensive test. 2) K is linear, and its change has nothing to do with the change of Reynolds number, to ensure the measurement results under higher than the range of 10:1 ratio, the measurement can reach + 0. The accuracy of 5%. 3) Power of the flow coefficient of flow meter more accurate than other meter, are more likely to know. Power and flow meter & Delta; Accuracy and stability of the p, and depends on the power meter unique scientific design: 1) In the shape of a small probe by traction zui, fluid and the probe of the separation point is fixed. 2) Power flow meter adopts full metal cavity structure, to avoid the other three type of probe structure caused by leakage between Chambers, increase the strength of the probe, and ensure its accuracy. 3) Low pressure hole in the probe lientang, probe and fluid separation point before, to avoid the low pressure hole affected by eddy current, and avoid the low pressure hole stuck, make the low voltage signal is more stable, more accurate measurement. 4) Rough surface treatment and the sedimentation tank, control the boundary layer, under various flow velocity, the fluid in the boundary layer on the surface of the probe is turbulent layer, guarantee the low velocity of the fluid when the probe is still stable accurate signal can be obtained. 5) Power and flow meter probe through the whole section of fluid, through multiple pressure hole take, take pressure hole spacing is obtained after area integral, the measured signal is to reflect the reality of the average speed of fluid signal. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
