Working principle thermal mass flow meters
Inside the meter, a small heater warms a section of the gas or liquid passing through. Sensors positioned on either side of this heater measure the temperature of the flow. As the gas or liquid moves, it carries away heat from the heated surface, causing a temperature drop that the sensors detect. The greater the flow, the more heat is absorbed, leading to a more significant temperature change.
Flow calculation
By analyzing how much heat is lost, the thermal mass flow meter can accurately calculate the mass flow rate, independent of the pressure or temperature of the gas or liquid. A thermal mass flow controller operates similarly but includes a control valve to adjust the flow rate automatically, ensuring precise delivery to processes.
With no moving parts, thermal mass flow meters and controllers provide reliable, real-time data, making them ideal for various applications such as process control, leak detection, and emissions monitoring. Their high accuracy, energy efficiency, and versatility make them suitable for demanding industrial environments.
