The TFM…V Variable Area Flow Meter is a reliable solution for monitoring the instantaneous flow rate of liquids and gases in industrial process systems. Designed for accurate visual measurement, this flow meter uses a transparent acrylic measuring tube and stainless steel float to indicate flow levels clearly and precisely.
Variable area flow meters, often called rotameters, are widely used across industrial automation, fluid control systems, and manufacturing plants where real-time monitoring of continuous flow is essential. The TFM…V series is specifically engineered for single-phase, non-pulsating liquid or gas flows, making it suitable for applications such as cooling circuits, water treatment systems, compressed air lines, and chemical processing installations.
Its robust construction and clear scale visibility enable operators to quickly verify flow performance, helping maintain operational efficiency and system safety.
Key Features
- Transparent acrylic measurement tube for clear flow visibility
- Stainless steel float for precise and stable flow indication
- High flow capacity up to 750 l/min liquids and 1400 Nm³/h gases
- Industrial-grade sealing options with silicone or FPM
- Durable polypropylene or ABS fittings for corrosion resistance
- Simple vertical installation for stable measurement performance
- Accurate flow indication with 4% precision
These features make the TFM…V flow meter suitable for both process monitoring and equipment protection in industrial fluid systems.
Design & Functionality
The TFM…V flow meter operates using the variable area measurement principle. As fluid or gas passes through the vertical measuring tube, the internal float rises proportionally to the flow rate. The float position aligns with the printed graduated scale, allowing operators to visually determine the flow value.
This mechanical measurement principle ensures stable operation without requiring electrical power, making it ideal for industrial environments where simplicity, reliability, and durability are critical.
The clear acrylic body enhances visibility while maintaining resistance to industrial fluids and moderate pressures.
Total Crossed Beams
The internal geometry of the measuring tube ensures stable float movement, minimizing turbulence and providing smooth flow indication. This design enhances measurement reliability and helps maintain consistent performance in continuous industrial processes.
Beam Pitch Options
Different measurement ranges are available across the TFM series to support varying system flow requirements. This flexibility allows engineers to select the correct model based on liquid flow capacity, gas flow range, and system pipe size.
Intrinsic Synchronism
The float and tube design naturally maintains measurement stability through gravitational balance and fluid dynamics. This intrinsic synchronism ensures consistent readings without the need for electronic calibration or complex adjustment.
Operational Advantages
Industrial facilities benefit from several operational advantages when using the TFM…V flow meter:
- Simple visual flow monitoring
- Low maintenance mechanical design
- No external power required
- Reliable operation in industrial environments
- Fast installation and easy system integration
Because of these advantages, the TFM…V series is widely used in industrial process control, cooling water systems, compressed air distribution networks, and chemical dosing systems where accurate and visible flow monitoring is essential.
