The flow meter operates based on the thermal mass flow measurement principle. Two temperature sensors are integrated into the measuring section of the meter. One sensor measures the actual process gas temperature, while a heated Pt100 thermal resistor is maintained at a constant temperature difference relative to the process temperature.
As the mass flow rate of the gas increases, the cooling effect on the heated sensor becomes stronger, requiring a higher electrical current to maintain the constant temperature difference. By monitoring the current supplied to the heating element, the instrument accurately calculates the gas mass flow rate.
This method enables direct mass flow measurement independent of pressure and temperature variations, ensuring stable and reliable performance.
The Micro Thermal Mass Gas Flow Meter is suitable for gas flow measurement and monitoring in the following fields:
Medical equipment and devices
Oil and gas industry
Chemical processing plants
Energy and power systems
