The thermal mass flow meter is a flow meter designed based on the principle of thermal diffusion. That is, when the fluid flows through the heating object, the heat loss of the heating object is proportional to the flow rate of the fluid.
The sensors of this series of flowmeters have two standard One is used as a heat source, and the other is used to measure the fluid temperature. When the fluid flows, the temperature difference between the two is in a linear
relationship with the flow rate, and then through the microelectronic control technology, this relationship Converted to a linear output of the measured flow signal.
