The Fast-Flo FMT Series Metal Tube Rotameter is a variable area flow meter specifically designed for extreme operating conditions. Unlike glass or acrylic tube rotameters, the FMT Series features sturdy construction to handle high pressure, high temperature, and aggressive media fluids, including gases.

The FMT Rotameter delivers reliable and accurate flow rate measurement for gas in closed pipelines, with the unique ability to measure and display the flow rate without requiring an auxiliary power supply for local reading. Its modular and adaptable design allows it to be customized for various customer-specific applications.

• Sturdy Construction: Engineered for high pressure, high temperature, and resistance to corrosive media.
• Self-Contained (Local Operation): Capable of locally measuring and displaying gas flow rate without electricity.
• Flexible and Adaptable: Modular design allows for adaptation to meet specific application needs (e.g., remote reading or signal transmission).
• Wide Measuring Range: Standard air measuring range covers 0.7 - 300m3/h (at 20oC, 0.1013MPa).
• Remote Capability: Remote options are available with standard 4-20 mA DC and HART output signals, and explosion protection (Exia IIC T7 or Exd IIB T4).
• High Accuracy: Offers high accuracy: more than 1.5% for local display and more than 1.0% for remote display.
