What are types of venturi meter?

Venturi meters are typically classified into three main types: standard Venturi meter, converging-diverging Venturi meter, and exponential Venturi meter. The standard Venturi meter features a uniform cross-section with a gradual converging section, a throat, and a diverging section, optimizing flow measurement. The converging-diverging type is designed to handle high-velocity flows, while the exponential variety has a tapered design that minimizes energy losses. Each type is used depending on the specific requirements of flow measurement applications.
