In the field of gas flow measurement, thermal gas flow meters have become a widely preferred instrument for many industrial scenarios. Their popularity stems from a combination of principle adaptability, easy installation, strong compatibility with varying process conditions, and excellent cost-effectiveness.
Principle Aligned with Gas Measurement — Stable and Reliable Data
Q&T QTMF series thermal gas flow meters operate on the thermal dispersion principle, enabling direct measurement of gas mass flow without the need for additional temperature and pressure compensation or volumetric flow conversion. Whether the medium is compressed air, natural gas, nitrogen, oxygen, or flue gas, these meters deliver stable readings that remain largely unaffected by minor fluctuations in pressure and temperature.
Compared to vortex and orifice plate flow meters — which only measure volumetric flow — thermal gas flow meters are better suited to the actual demands of gas process conditions, providing more meaningful and actionable measurement data.
Wide Turndown Ratio — Precision Even at Low Flow Rates
One of the standout features of QTMF series thermal gas flow meters is their exceptionally wide turndown ratio, typically ranging from 100:1 to 1000:1.
This broad range allows them to handle large-flow measurement scenarios while also accurately capturing minute gas flows.
In low-velocity, small-flow conditions where other technologies such as orifice plates and turbine meters often struggle with data inaccuracy, thermal gas flow meters maintain their precision — making them an ideal choice for applications that demand reliable measurement across a wide spectrum of flow rates.
Minimal Pressure Loss — Long-Term Energy Savings
QTMF series Thermal gas flow meters feature an internal design with no throttling components and no moving parts. As gas passes through the meter, pressure loss is extremely low, preserving pipeline pressure and avoiding unnecessary energy consumption.
