Product Description
Advanced DN150 Metal Tube Rotameter Magnetic Coupling Accurate Flow Design

The Advanced DN150 Metal Tube Rotameter is a heavy-duty variable area flow meter engineered for high-volume industrial flow measurement. Specifically designed for DN150 (6-inch) pipelines, this meter utilizes a sophisticated non-contact magnetic coupling system to provide accurate and real-time flow data for liquids, gases, and steam in the most demanding environments.

Constructed with a robust all-metal body, the DN150 series eliminates the risks associated with glass tube meters, making it the ideal choice for high-pressure, high-temperature, and hazardous industrial applications.
