The AI.F Series is the professional solution for instant visual monitoring of liquid and gas flow within pipelines. Designed to withstand harsh industrial conditions, these indicators allow you to easily and safely verify flow direction, clarity, and fluid movement.
Why choose the AI.F Series?
Easy Observation: Available with or without a spring-loaded vane to visualize fluid flow in any direction and at various flow rates.
Maximum Robustness: Made of high-quality materials such as AISI 316, 316L, or 304 stainless steel and high-resistance tempered glass.
Operational Versatility: They withstand operating temperatures up to 200°C (with a special option up to 300°C) and high pressures, adapting to almost all industrial systems.
Advanced Security: The FB-DP model includes an external metal protective grille to prevent accidental damage to the glass, while the double-glazed version offers an additional level of security.
