摘要： PROBLEM TO BE SOLVED: To provide a fluid flow rate measuring device capable of obtaining desired stream lining effect by a mesh as suppressing a pressure loss. SOLUTION: In a gas meter 1 interposed halfway on a gas piping connected to a gas supply source at its upstream side and to a gas consuming source at its down stream side, the flow speed of gas is measured by using a microprocessor sensor 5 provided at the downstream side of the corner 3a of a passage 3. When finding the flow of the gas passing 3 through the passage 3 by a microcomputer 13 by multiplying it by the cross section of the passage, the stream lining effect required to uniform the flow speed distribution of the gas reaching three spots of the passage in each of which the microprocessor sensor 5 is provided can not be singly obtained between the corner 3a and the three spots of the passage where the microprocessor sensors 5 are provided. Therefore, a coarse mesh 17 and a relatively fine mesh 19 are disposed.

摘要： PROBLEM TO BE SOLVED: To provide a more precise gas densimeter and a gas density measurement method, while being simple in constitution and low in price.
SOLUTION: A pocket section 21 is formed in a recessed shape on the inner wall of a gas channel 20 where gas to be measured passes, and a microflow sensor 1', having first to fourth thermopiles, is mounted into the pocket section 21. Then, the density of the gas to be measured is obtained by using at least either one of the first to fourth temperature detection signals outputted from each of the first to fourth thermopiles. Or, at least two of the first to fourth thermopiles are utilized to obtain the density of the gas to be measured. Furthermore, to prevent influence of the flow of the gas to be measured passing through the gas channel 20, the aperture of an opening 21A leading from the pocket section 21 to the gas channel is made sufficiently smaller than the volume of the pocket section 21.

摘要： PROBLEM TO BE SOLVED: To provide a bottom face flow passage unit capable of creating a wide plane space for arranging a substrate in an upper side from a bottom face part of a gas meter front face, and to provide a gas meter incorporated therewith.
SOLUTION: A sheetlike unit lid part 12 is matched in an underface of a unit body part 11. The unit body part 11 and the unit lid part 12 are fixed via screw-fastened flange parts 111, 121 projected from positions corresponding respectively to the lowest side face part of the unit body part 11 and a side face of the unit lid part 12. Screw-fastening work is facilitated in the unit body part 11 and the unit lid part 12, because the screw-fastened flange parts 111, 121 are projected. The wide plane space for arranging the substrate free from regulation by the projected flange parts 111, 121 is generated in the upper part of the projected screw-fastened flange parts 111, 121, i.e. the upper side from the bottom face part of the gas meter front face, after screw-fastened.
