What is one advantage of the Venturi in comparison to an orifice plate?

The Venturi has advantages over an orifice plate, particularly regarding its longevity and durability. The shape of the Venturi allows for a smoother flow path, which means that there is less turbulence compared to an orifice plate. With reduced turbulence, there is less erosive wear on the material, allowing the Venturi to maintain its dimensions and performance over time. This leads to a longer lifespan and reduces the need for frequent maintenance or replacement.

In contrast, orifice plates are more susceptible to wear and damage due to their design, which creates significant turbulence as fluid flows through a sharp-edged opening. This turbulence can cause significant erosion over time, affecting measurement accuracy and requiring more frequent replacements.

The combination of these factors underscores the benefit of using a Venturi for applications where durability and less frequent replacement are critical considerations.
