Abstract: An intelligent flow/temperature measuring device includes a circuit portion having a microcontroller unit, to which a temperature sensor, a flow sensor, a temperature display unit, and a flow display unit are connected, such that signals output by the temperature and flow sensors are transmitted to and processed by the microcontroller unit, and the processes data are separately displayed on the temperature and flow display units. The flow sensor includes a flow speed and a temperature sensing resistor, which are used to sense flow speed and temperature, respectively, and connected to the microcontroller unit via an A/D converting circuit each and to two inputs of a differential amplifying circuit. The differential amplifying circuit has an output connected via an A/D converting circuit and a filter circuit to the microcontroller unit. With these arrangements, the intelligent flow/temperature measuring device is more convenient for use.
