The AI.FW Series is the ideal solution for immediate visual monitoring of the movement of liquids and gases in pipes. Thanks to the internal impeller system, even minimal flow rates can be detected and the direction and flow of the process can be instantly verified simply and effectively.

Strengths
Dynamic Visualization: The colored impeller rotates as the fluid passes, providing a clear visual signal even from a distance, making it perfect for transparent gases and liquids.
Multiple Configurations: Available with single or double windows (for through-viewing) and with threaded or flanged connections to adapt to any industrial system.
High Thermal Resistance: Thanks to the choice of rotor materials, such as glass-filled PPS, the instrument can operate safely up to 200°C.
High Pressure Version: The FW-4 model is specifically designed for high-pressure applications, supporting up to 80 bar.
