I. Basic Principles and Current Status of Orifice Plate Flow Meters

1. Basic Principles

Orifice plate flow meters are designed based on the throttling principle in fluid mechanics. When fluid flows through the orifice plate, due to the throttling effect of the orifice plate, the flow velocity of the fluid increases, and the pressure decreases, forming a pressure difference. By measuring the pressure difference, combined with the geometric dimensions of the orifice plate and the physical properties of the fluid, the flow rate of the fluid can be calculated. The basic formula is:

[ Q = C \cdot A \cdot \sqrt{\frac{2\Delta P}{\rho}} ]

Where, (Q) is the flow rate, (C) is the flow coefficient, (A) is the orifice opening area, (ΔP) is the pressure difference, and (ρ) is the fluid density.
