Industrial Gas Mass Flow Measurement
Direct gas mass flow monitoring without pressure or temperature compensation.
TMF2X is a high-performance thermal mass flow meter designed for accurate and reliable gas flow measurement in industrial applications.
Using thermal diffusion technology with a constant temperature differential principle, it directly measures gas mass flow for stable readings under changing operating conditions.
Introduction
The TMF2X directly measures gas mass flow without requiring pressure or temperature compensation. This makes it suitable for applications where gas conditions may vary and reliable measurement is required.
The meter uses dual platinum resistance temperature sensors. One sensor continuously measures 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.
Its fully digital design, robust construction and maintenance-free operation make it ideal for long-term gas monitoring applications in industrial, utility and energy management environments.
