Preface:

In today's industrial field, accurate measurement of fluid flow is crucial for optimizing production processes, improving energy efficiency, and ensuring product quality. Orifice flow meter As a common flow measurement device, it plays a key role in many industries due to its simple structure, reliable performance, and wide applicability. And Imported orifice flow meter is favored for its advanced technology and excellent quality. This article will delve into the precise measurement principles and applications of imported orifice flow meters, allowing you to appreciate its unique charm in the field of industrial measurement.

I. Working principle of orifice flow meter

The working principle of the orifice flow meter is based on the Bernoulli equation and the continuity equation. When fluid passes through a sharp-edged orifice plate, the velocity increases, and the pressure decreases. By measuring the pressure difference before and after the orifice plate, combined with the known fluid characteristics and geometric parameters of the orifice plate, the fluid flow rate can be calculated.

Specifically, when the fluid flows through the orifice plate, due to the sudden reduction in the flow area, the flow velocity reaches its maximum value at the orifice plate, and the pressure decreases accordingly. According to the Bernoulli equation, there is a certain relationship between flow velocity and pressure. At the same time, according to the continuity equation, under steady flow conditions, the mass flow rate of the fluid passing through any cross-section of the pipe is constant. By measuring the pressure difference before and after the orifice plate and using the corresponding calculation formula, the fluid flow rate can be accurately determined.
