Thermal Mass Flow Meter MT-F100TM

1. Introduction to Thermal Mass Flow Meter MT-F100TM

The Thermal Mass Flow Meter MT-F100TM is a highly accurate and advanced flow measuring device designed for direct measurement of mass flow rate in clean and single-phase gases. This flow meter operates based on the thermal dispersion principle, which allows it to measure gas flow without the need for external temperature or pressure compensation instruments. As a result, it is widely used in applications requiring precise flow control, energy measurement, and gas consumption monitoring.

The Thermal Mass Flow Meter MT-F100TM offers excellent performance in terms of accuracy, stability, and ease of installation, making it a preferred solution in industrial process systems, environmental monitoring applications, and gas distribution networks. With its ability to directly measure mass flow, users benefit from simplified system design, reduced installation cost, and reliable long-term operation.

2. Working Principle

The MT-F100TM thermal mass flow meter uses the thermal dispersion principle to determine the flow rate. A pair of temperature sensors, usually platinum RTDs, are embedded in the flow tube. One of the sensors is heated while the other measures the reference temperature of the flowing gas. As the gas flows, it carries heat away from the heated sensor at a rate proportional to the mass flow of the gas. The system continuously measures the energy required to maintain the temperature differential between the sensors. This energy is directly correlated with gas mass flow.

Unlike traditional flow meters that require separate sensors to measure temperature and pressure for compensation, the thermal mass flow meter directly calculates the gas mass flow, simplifying installation and enhancing accuracy.

6. Installation Considerations

For accurate measurement, proper installation is critical. The MT-F100TM should be installed in a section of the pipeline where the gas flow is stable and fully developed. The recommended straight pipe lengths are:

• A minimum of 10 diameters upstream of the sensor.

• A minimum of 5 diameters downstream of the sensor.

Avoid installation near elbows, valves, blowers, and pumps where turbulence is high. For insertion types, correct insertion depth must be maintained to ensure the sensor is positioned properly in the flow profile.
