浅谈差压式流量计的工作原理及选型

摘要

A differential pressure flowmeter is a relatively wide range of differential pressure flowmeter types one, it has a simple structure, a wide range of applications, ease of maintenance, and ease of production, and other characteristics of standard parts, which is widely used in the petroleum and petrochemical industries. Analysis of the differential pressure flowmeter works and selection, to provide a theoretical basis for the future differential pressure flowmeter selection and optimization.%　　差压式流量计是目前比较广泛的差压式流量计种类之一，它具有结构简单，应用范围广，便于维修，且标准件便于生产等特点，因而广泛的应用于石油石化行业。文章主要浅析了差压式流量计的工作原理和选型，为今后差压式流量计的选型和优化提供一定的理论依据。
