Overview
The M140RTAL1 is a variable area vane flow meter from Universal Flow Monitors, engineered for direct flow measurement in industrial automation and process control systems. This M-Series meter employs spring-biased vane technology to provide accurate, mechanical flow indication without external power. The M140RTAL1 delivers continuous local flow rate visibility via mechanical pointer display, making it ideal for applications where visual confirmation of flow is critical.
Key Features
- Spring-biased semi-circular vane design for stable, reliable operation across varying flow conditions
- Variable area flow measurement with mechanical pointer indication for direct visual readout
- Installation-flexible design compatible with in-line positioning in any orientation
- No external power required—fully mechanical operation simplifies integration into existing systems
- Optional mechanical switch and transmitter connections for alarm and remote monitoring
- Corrosion-resistant construction suitable for water, oil, and standard process fluids
