Abstract: A gas flow measuring device for flow meter calibration is provided to prevent the change of a calibration value due to the change of temperature and to automate the calibration process by the control of a computer program. A gas flow measuring device for flow meter calibration includes a divergence bank(1), a plurality of flow divergence pipes(3), a confluence bank(4), and a controller(5). The divergence bank has a pressure sensor(11) and a temperature sensor(12), and is connected to a flow pipe. The flow divergence pipes are connected to a sonic nozzle(31), and equipped with air pressure valves(32). The confluence bank is connected to the end of the flow divergence pipe to join the gas transferred to each flow divergence pipe. The controlling device controls the air pressure valve and a flow meter(6), and receives the information sensed from the air pressure valve and the flow meter to calculate a calibration value.

Abstract: PURPOSE: A thermal mass flow sensor is provided to irregularly form intervals of each thermocouple forming a thermopile and a heating unit so that precise measurement sensitivity within a wide flow rate range is obtained. CONSTITUTION: A thermal mass flow sensor includes a thin film (210), a heating unit (220), and first and second thermopiles (231, 232). The heating unit is formed on the thin film. The first and second thermopiles connect the thermocouples on the upper and lower streams of the heating unit in a row. Intervals of each thermocouple and the heating unit are irregularly formed so that the first and second thermopiles improve measurement sensitivity regardless of flow rate range.

Abstract: PURPOSE: A thermal mass flow sensor is provided to vary only a voltage supplied to a heating unit, thereby obtaining precise measurement sensitivity without changing the structure of a basis thermal mass flow sensor. CONSTITUTION: A thermal mass flow sensor includes a thin film (110), a heating unit (120), first and second thermopiles (131, 132), a control unit (140), and a voltage converter (150). The heating unit is formed on the thin film. The first and second thermopiles connect thermocouples on the upper and lower streams of the heating unit in a row. The control unit varies a heater output of the heating unit, thereby generating heater output controlling signals varying intervals of the first and second thermopiles and the heating unit. The voltage converter varies an output voltage supplied to the heating unit according to the heater output controlling signals generated by the control, thereby supplying to the heating unit.
