Measuring small flow rates often requires expensive equipment and is associated with inherent limitations. In practice, various measuring structures, such as weirs, are commonly constructed at specific locations to facilitate flow measurements. This paper proposes an innovative and low-cost measurement structure made from sewer pipes, incorporating a "V-notch" weir design that can be used under various conditions to measure flow simple and effectively. Laboratory calibration of the weir coefficient was carried out, and ten equations (models) were developed to minimize relative error. The experimental results were compared with existing equation expressions from the literature. Furthermore, the study explores the practical implementation of the proposed weir design. The aim of the study is to demonstrate the feasibility of this solution, highlighting its low construction cost and adaptability for application in diverse field conditions.
