Preface:

In today's era of rapid technological development, the aerospace and marine fields are experiencing unprecedented technological advancements. Accurate flow measurement is crucial for the operation and development of these fields. Orifice flow meter As an important flow measurement tool, it plays an indispensable role in the aerospace and marine fields. With its unique advantages and reliability, it provides strong support for the smooth progress of aerospace and marine engineering. This article will delve into the application of orifice flow meters in flow measurement in the aerospace and marine fields, allowing you to appreciate its excellent performance in these two challenging and opportunistic fields.

I. Working principle of orifice flow meter

Orifice flow meters primarily operate based on Bernoulli's theorem and the continuity equation. When fluid flows through a throttling device (such as an orifice plate), the fluid velocity increases, while the pressure decreases. By measuring the pressure difference before and after the orifice plate, and combining the known fluid characteristics and pipe parameters, the fluid flow rate can be calculated.

II. Importance of orifice flow meters in aerospace

In the aerospace field, precise flow measurement is crucial for spacecraft propulsion systems, fuel supply systems, etc. For example, in spacecraft engines, it is necessary to accurately measure the fuel flow rate to ensure the normal operation of the engine and precise control of the spacecraft. Orifice flow meters, with their high accuracy, high stability, and reliability, have become one of the preferred tools for flow measurement in the aerospace field.
