The Fast-Flo FFA-AT and FFC-T Series Acrylic Rotameter (formerly known as the LZM-ZT model) is a flow meter type featuring an acrylic body and a clear viewing design. This series is engineered to provide easily readable flow measurements across a large measuring range.

This rotameter is ideally suited for gas applications, as it is equipped with SS (Stainless Steel) valves that allow for precise flow rate adjustment. Its key features include an attractive appearance (beautiful look) and straightforward installation, making it a popular choice for gas flow control in laboratories, process air monitoring, and other low/medium pressure applications.

• Clear Flow Visualization: The transparent acrylic tube ensures a clear view of the float for real-time and accurate gas flow rate readings.
• Precision Flow Control: Equipped with Stainless Steel (SS) valves, users can easily and accurately adjust and regulate the gas flow rate.
• Large Measuring Range: Capable of operating across a large measurement span, providing flexibility in gas applications.
• Easy Installation: The compact design and standard threaded connections (NPT/BSP) guarantee quick and easy installation.
• Guaranteed Accuracy: This rotameter series offers reliable accuracy of $\pm 4\%$ of Full Scale (F.S.).
