Thermal mass flow meter
A thermal mass flow meter includes a housing, a control module, a plurality of probes, a flow calculation circuit, and a heating module. The control module is installed in a containing space. The probes are connected to one terminal of the housing. The flow calculation circuit is connected to the control module, and has a plurality of circuit boards installed in the probes and a plurality of temperature sensing units connected to the circuit boards. The heating module is connected on one of the circuit boards, and connected to the control module. The control module controls the heating module to heat a working fluid in a pipeline; the flow calculation circuit senses the temperature inside the pipeline to acquire temperature change values, and transmits the temperature change values to the control module; and the control module measures the fluid velocity of the working fluid.
