Measurement Principle
The measurement principle is based on a MEMS "Micro Thermal Flow Sensing". The Fig 1 has shown that there is a micro-heating element and two temperature sensors are placed around it. The temperature difference between the two sensors will be created when the flow rate increases and it is proportional to the mass flow rate.
