摘要： A thermal conductivity measuring device includes a diaphragm portion, a thermal conductivity detector, a temperature sensor, a control section, and a thermal conductivity calculating section. The diaphragm portion is formed on a base. The thermal conductivity detector is formed in the diaphragm portion to perform conduction of heat to/from a sample gas. The temperature sensor is disposed on the base to be near the thermal conductivity detector so as to measure the ambient temperature around the base. The temperature sensor is thermally insulated from the thermal conductivity detector. The control section controls the amount of energy supplied to the thermal conductivity detector such that the temperature difference between the ambient temperature measured by the temperature sensor and the heating temperature of the thermal conductivity detector becomes a constant value. The thermal conductivity calculating section calculates the thermal conductivity of the sample gas on the basis of the amount of energy supplied to the thermal conductivity detector while the temperature difference is kept at the constant value by the control section.

摘要： A diaphragm-type sensor is disclosed which comprises a substrate including a cavity, a diaphragm formed on the cavity and supported by the substrate, a heater element arranged on the diaphragm, two sensor elements arranged on both sides of the heater means and slits between the heater means and the respective sensor means. The slits are effective in completely preventing the deformation of the diaphragm due to a heat propagated from the heater element, from influencing the sensor elements, whereby the diaphragm-type sensor exhibits stable output characteristics.

摘要： This flow meter uses two known flow responsive techniques and combines them in a unique structure and system to form an improved flow meter whose range extends from low to high flow rates. The meter comprises a flow tube with a region of reduced diameter between its inlet and outlet. A microbridge flow sensor of a suitable type known in the art, which responds to thermal changes caused by changes in the flow rate, is located in the region of reduced diameter. A post downstream of the microbridge sensor creates Karman vortices whose frequencies are a function of flow rate and which are detected through ports in the tube by a suitable detector. The output of the microbridge is linear from low flow rates to a mid range and the Karman flow meter output is linear from the mid range to high flow rates. A correction factor is applied to the thermal flow meter output. The correction factor is determined by a ratio of the Karman flow meter output to the thermal output for a flow rate in the mid range, allowing a smooth transition from thermal to Karman outputs and vice versa in the mid range.

摘要： A flow sensor comprising a flow passage, a rectifying element such as a plurality of screens or a honeycomb structure or both, arranged in the flow passage, a flow passage reducer for reducing the flow passage behind the rectifying element, and a thermal flow sensor, such as for example a micro bridge sensor, mounted at a location immediately behind the reducer. The above structure can largely reduce disturbance in flow to thereby enable highly accurate measurements of a wide range of flow without a low pass filter.

摘要： A simply structured flowmeter in which an influence of a dilatational wave on a thermal flow rate sensor is suppressed, and measurement accuracy is enhanced.The flowmeter has not only the thermal flow rate sensor that is placed to face a flow channel and detects a flow rate of fluid flowing through the flow channel but also a micro path (for example, narrow pipe) that is provided to the flow channel and blocks a dilatational wave created in the flow channel from being transmitted to the thermal flow rate sensor.
