TMF2X is a high-performance Thermal Mass Flow Meter designed for accurate and reliable gas flow measurement in industrial applications. Utilizing advanced thermal diffusion technology with a constant temperature differential principle, the TMF2X directly measures gas mass flow without requiring pressure or temperature compensation, ensuring stable and precise readings under varying operating conditions.
The meter employs dual platinum resistance temperature sensors, where one continuously monitors the actual gas temperature while the other is heated to maintain a fixed temperature differential. As gas flows across the sensor, the cooling effect is measured and converted directly into mass flow rate, delivering highly accurate and repeatable results. Its fully digital design, robust construction, and maintenance-free operation make it ideal for long-term gas monitoring applications.
TMF2X is suitable for measuring a wide range of gases in industrial processes, compressed air systems, energy management applications, environmental monitoring, and utility metering. With support for both insertion and flanged installations, along with RS485 communication and multiple output options, it seamlessly integrates into PLC, SCADA, and industrial automation systems.
