Abstract
A device for measuring the flow-rate of gas in a duct, particularly for burners. The device includes a gas flow-rate sensor generating a first output signal proportional to the flow-rate detected, a temperature-compensation circuit receiving the first output signal and generating a second output signal proportional to the gas flow-rate detected by the sensor and independent of the temperature of the gas and/or the flow-rate sensor. The compensation circuit has a temperature sensor. The device also includes a calibration circuit receiving the second output signal. The calibration circuit generates a third output signal proportional to the gas flow-rate detected and independent of structural parameters of the flow-rate sensor and/or of the temperature sensor so that the third output signal is correlated with the flow-rate detected and independent of the temperature of the gas, the temperature of the flow-rate sensor, and the structural parameters of the flow-rate sensor.
