ABSTRACT:
A thermal flow sensor constructed by a temperature control circuit which includes a bridge circuit consisting of a thermoresistor arranged in a fluid passageway and a plurality of resistors, and a correction circuit for correcting the output of the control circuit in accordance with a gradient of a flow rate detecting characteristic is described. The correction circuit includes a subtracting circuit for subtracting a predetermined value from an output of the control circuit, a voltage dividing circuit for dividing an output of the subtracting circuit and an arithmetic operating circuit for performing either an addition or a substraction between outputs of the dividing circuit and the control circuit. The correction circuit may further include an amplifying circuit for amplifying the output of the dividing circuit and may change the arithmetic operating circuit to the circuit for adding the outputs of the arithmetic operating circuit and the control circuit and for subtracting the output of the subtracting circuit from the added voltage.
