Import Orifice plate flow meter As a high-precision, high-reliability flow measurement device, it is widely used in various stages of the pharmaceutical industry. This article will detail Import Orifice plate flow meter its working principle, technical characteristics, application scenarios, and its important role in the pharmaceutical industry.

I. Basic Principle of Orifice Plate Flow Meter

The orifice plate flow meter is a flow measurement device designed based on the Bernoulli equation and the continuity equation. Its basic principle is to install an orifice plate with an aperture in the pipeline. When the fluid flows through the orifice plate, it will cause local contraction, increasing the flow velocity and decreasing the pressure. By measuring the pressure difference before and after the orifice plate, the flow velocity and flow rate of the fluid can be calculated.

Specifically, when the fluid flows through the orifice plate, the fluid pressure before the orifice plate is P1, and the fluid pressure after the orifice plate is P2. Due to the throttling effect of the orifice plate, P2 is less than P1. According to the Bernoulli equation and the continuity equation, the flow velocity and flow rate formula of the fluid can be derived:

[ Q = C \cdot A \cdot \sqrt{2g \Delta h} ]

Where:

• (Q) is the fluid flow rate
• (C) is the flow coefficient
• (A) is the orifice area of the orifice plate
• (g) is the acceleration of gravity
• (Δh) is the pressure difference before and after the orifice plate
