Metlan Instruments, a global provider of industrial flow measurement and control solutions, announces the continued expansion of its Precision Thermal Mass Flow Controller portfolio, reinforcing its commitment to accurate, stable, and automation-ready gas flow control for laboratory and industrial applications.
As demand increases for reliable Mass Flow Controller solutions in semiconductor manufacturing, analytical instrumentation, gas mixing systems, and advanced process automation, Metlan delivers a focused range of thermal mass flow technologies designed to meet both standard and low-flow gas control requirements.
Precision Thermal Mass Flow Control with MTL20FD
The MTL20FD Thermal Mass Flow Controller is engineered to provide direct mass-based gas flow measurement and closed-loop control using proven thermal sensing principles. By measuring heat transfer within the gas stream, the controller determines true mass flow independent of pressure and temperature fluctuations, eliminating the need for external compensation.
Designed for a wide range of industrial and laboratory gases—including nitrogen, oxygen, hydrogen, carbon dioxide, and specialty gas mixtures—the MTL20FD delivers stable and repeatable control across diverse operating conditions.
Key features include:
- Direct thermal mass flow measurement and control
- High accuracy and excellent repeatability for process stability
- Fast response suitable for dynamic gas dosing and switching
- Multiple signal outputs and digital communication options for PLC and automation systems
- Rugged construction with options for high ingress protection and industrial environments
The MTL20FD is widely applied in semiconductor processes, gas delivery systems, environmental testing, and analytical equipment where flow stability directly impacts performance and product quality.
Low-Flow Mass Flow Controllers for Ultra-Precise Gas Regulation
For applications requiring extremely small and stable gas flows, Metlan offers a dedicated Low-Flow Mass Flow Meter & Controller solution optimized for enhanced sensitivity and resolution.
These low-flow Mass Flow Controllers are specifically designed to:
- Maintain precise control at very low flow rates
- Deliver high signal stability and repeatability
- Support closed-loop regulation for micro-dosing and analytical processes
- Integrate easily into automated laboratory and OEM systems
Typical applications include gas chromatography, laboratory research, microreactors, calibration systems, and specialty gas delivery where standard controllers may lack sufficient resolution.
Why Precision Thermal Mass Flow Controllers Matter
Unlike volumetric flow devices, thermal Mass Flow Controllers regulate gas flow based on true mass, ensuring consistent performance even when gas density varies due to changes in temperature or pressure. This capability is essential in modern gas processes where accuracy, repeatability, and automation are critical.
Thermal Mass Flow Controllers provide:
- Direct mass flow control without external compensation
- Reliable low-flow performance
- Fast and stable closed-loop response
- Simplified system design and integration
These advantages make them indispensable in high-precision gas control systems across multiple industries.
