layouts and connections such as SMD and wired configurations are available. Flow. Measurement Principle. Thermal mass flow sensors utilize heat transfer principles to determine the flow velocity of a fluid. As fluid passes across the sensor, heat is carried from the sensor to the medium. This relationship is dependent upon the flow rate. As flow increases, so does the amount of heat that is transferred. By knowing the temperature of the medium, the flow rate can be determined from...
