DN 50 flow meter is a general-purpose, 2-inch nominal size flow meter commonly used in various industries to measure the flow of liquids and gases in closed pipelines. It finds applications in municipal water supply and wastewater treatment, chemical and petrochemical processes, the paper and pulp industry, power plants, and the food and beverage sector. Because the DN 50 is a standard size, it's suitable for a broad range of industrial and environmental measurement tasks where a mid-sized pipe diameter is required for monitoring flow.
