Inside the air and gas flow meter, a small tube or sensor allows gas to flow through. This sensor typically includes a heated element and one or more temperature sensors. As gas flows through the sensor, the flow meter heats it using the heated element. The gas absorbs some of this heat as it passes over the element. The temperature sensors then detect the resulting temperature difference between the heated element and the gas.

This temperature difference is directly proportional to the mass flow rate of the gas moving through the sensor. By accurately measuring this temperature difference and considering factors such as the specific heat capacity of the gas, the flow meter calculates the mass flow rate. This calculated rate is then displayed on the digital readout of the flow meter.

To ensure precise measurements across different flow rates and gas types, flow meters like the Vogtlin Red-y Compact 2 are often calibrated specifically for various gases. This calibration process enhances accuracy and reliability in industrial applications.

Moreover, the Vogtlin Red-y Compact 2 mass flow meter utilizes thermal dispersion principles. This means it accurately measures gas flow rates by heating the gas and analyzing the resulting temperature difference. This approach not only ensures precision but also provides reliable measurements suitable for a wide range of industrial processes.

Additionally, these flow meters can output signals, such as analog or digital signals, which can be integrated into control systems or data-logging devices. This capability enhances their utility in industrial automation and monitoring applications.”
