  • Fluid-measuring device and fluid-measuring method
    Patent number: 7467547
    Abstract: A fluid-measuring device intermittently drives a heater during a measurement period and receives outputs of the lateral side temperature sensors as lateral side temperature signals upon non-driving whenever the heater stops heating during a measuring period. Then, the fluid-measuring device receives outputs of the lateral side temperature sensors in response to the heating of the heater 4 as lateral side temperature signals upon driving corresponding to the lateral side temperature signals upon non-driving. The fluid-measuring device also receives upstream and downstream side temperature signals outputted from upstream and downstream side temperature sensors corresponding to the lateral side temperature signals upon driving. The fluid-measuring device detects physical properties data of the fluid on the basis of the lateral side temperature signal upon non-driving and the lateral side temperature signal upon driving.
