Description
1. Introduction to Micro Metal Tube Rotameter MT-F320RT
The Micro Metal Tube Rotameter MT-F320RT is a precision-engineered flow measurement instrument designed specifically for applications where very low flow rates, high pressure, and high temperature conditions are present. Unlike traditional glass or acrylic rotameters where the float is visible inside the transparent tube, the MT-F320RT employs a metal measuring tube, making it highly resistant to mechanical damage, corrosion, and extreme operating environments. This makes it suitable for demanding industrial applications, such as process plants, chemical dosing lines, pharmaceutical manufacturing, and compressed gas systems.
The defining feature of the Micro Metal Tube Rotameter MT-F320RT is its magnetic coupling system, where the float movement inside the metal tube is transmitted magnetically to an external pointer visible on the scale. This design ensures reliability, safety, and long-term accuracy even when handling aggressive, opaque, or contaminated fluids.
2. Key Functional Principle and Design Advantages
The Micro Metal Tube Rotameter MT-F320RT operates based on the variable area flow measurement principle. As the fluid flows through the tapered metal tube, the float inside rises or falls depending on the flow rate. However, since the tube is metallic and not transparent, the float cannot be seen directly. Therefore, a magnetic coupling mechanism is used to transfer the float position to the external indicator. This allows the flow reading to be displayed clearly and continuously without direct fluid contact.
Main Design Advantages:
-
Heavy-duty construction suitable for high-demand industrial systems.
-
High temperature and high pressure resistance, making it ideal for harsh environments.
-
Wide rangeability, allowing accurate readings even in low flow conditions.
-
Optional built-in control valve that enables flow regulation in addition to flow measurement.
-
Low maintenance and easy replacement capabilities reduce downtime.
-
Compact structure suitable for limited installation spaces.
3. Construction Materials and Durability
The Micro Metal Tube Rotameter MT-F320RT is designed with robustness in mind. The body and internal components are engineered to handle corrosive fluids, abrasive media, and long-term vibration exposure. The magnetic transmission system is sealed and isolated, ensuring no leakage or contamination.
Because there is no fragile glass tube, the instrument is far more durable than conventional glass rotameters. This reduces the risk of breakage, accidental pressurization failures, or response deviations over time. For industries requiring continuous operation with minimal maintenance interruptions, the MT-F320RT provides an excellent reliability advantage.
4. Performance Features of Micro Metal Tube Rotameter MT-F320RT
