Abstract
The flow amount measuring apparatus has two detecting portions for generating signal indicative of flow amount respectively. The outputs of two detecting portions are subject to a differential amplification to obtain large output signal and low amplitude ratio. A plurality of resistors providing the detecting portion may be formed on a single substrate. The output characteristic of the flow amount measuring apparatus can be adjusted by adjusting the gain and the offset. The offset includes a temperature dependent first offset component and a constant second offset component. The first offset component varies in accordance with temperature of fluid so as to reduce temperature dependency of the output characteristic. As a result, it is possible to measure flow amount accurately.
