Abstract: A thin film is formed on a substrate on which an opening having two opposite sides are formed, and forms a membrane. The thin film has an upstream temperature sensor and a downstream temperature sensor on both sides of a heater. A heat conductive member covers the two sides and is arranged on both sides of the heater, the upstream temperature sensor, and the downstream temperature sensor so as to promote heat conduction from the heater to the substrate. When an end of the opening on the membrane side is defined as an upper end and an end on the side away from the membrane is defined as a lower end, the heat conductive member covers from the upper end to the lower end of the opening in a normal direction of the membrane.

Abstract: A flow detecting device is provided to a fluid passage through which a main flow of fluid passes. A sensor body has a bypass passage through which a bypass flow passes from the main flow. The bypass passage has a bent portion, which is located midway through the bypass passage, and an outflow passage, which is located downstream of the bent portion.

The sensor body has a side surface defining an opening through which dynamic pressure caused by counterflow is released to an outside of the outflow passage when fluid causes counterflow in the fluid passage in a direction opposite to a flow direction of the main flow.

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.

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 and outputted. As a result, it is possible to obtain large output. Large output enables lowering of an amplitude ratio of an amplifier portion. As a result, adjusting the amplifier portion becomes easy. A plurality of resistors providing the detecting portion may be formed on a single substrate by the same manufacturing process. As a result, it is possible to reduce errors of the resistors. In addition, the flow amount measuring apparatus may be constructed so that gain and offset of the amplifier portion are adjustable. The output characteristic of the flow amount measuring apparatus can be adjusted by adjusting the gain and the offset.
