What is a Square Edged Orifice Plate?
The Arrotop Square-Edged Orifice Plate (Model Number: ARO-SEOP-008) is a precision-engineered device widely utilized for fluid flow measurement. Renowned for its simple structure, high accuracy, and ease of installation, this orifice plate is ideal for measuring flow rates in clean liquids, gases, and steam. It adheres to stringent dimensional, surface roughness, and flatness standards, ensuring reliable performance in various industrial applications.
Product Data
Arrotop’s Square-Edged Orifice Plates are designed for versatility and precision. They provide accurate measurement of flow rates by creating a differential pressure drop across the orifice. This design is particularly suitable for general applications involving clean fluids, offering excellent repeatability and accuracy. The square-edged orifice is characterized by a sharp edge that appears identical from either direction, making it ideal for bi-directional flow measurement.
