    摘要： A fluidic gas meter including a flow path structure provided with a fluidic element, a cut-off valve, a pressure switch, a flow sensor, a piezoelectric film sensor, an electronic circuit unit, and a wiring board serving as a mother board and having a function of lead wires. Each of the cut-off valve, the pressure switch, the flow sensor and the piezoelectric film sensor are fixed to the flow path structure. The electronic circuit unit is made up of a counter board and a control circuit board. The counter board is mounted with an electronic circuit for counting up flow-rate signals from the flow sensor and the piezoelectric film sensor and a liquid crystal display device for displaying the amount of gas consumed. The control circuit board is mounted with a control circuit for controlling the cut-off valve, wherein each of the cut-off valve, the pressure switch, the flow sensor, the piezoelectric film sensor and the electronic circuit unit is provided with a plurality of terminals extending perpendicularly to the wiring board. The wiring board is provided with a printed circuit for the interconnection among the terminals. The wiring board has a plurality of V-shaped guide grooves formed therein for receiving the terminals and guiding the terminals to through holes formed at an apex of the V-shape of the guide grooves, wherein the terminals form an electrical connection with the printed circuit of the circuit board, thereby avoiding wiring errors.

    摘要： In a fluidic flowmeter for measuring the flowrate higher than the preset flowrate by use of a fluidic element and for measuring the flowrate lower than the present flowrate by use of a flow sensor inserted into the nozzle portion, the present invention relates to the fluidic flowmeter that has an abnormality judging circuit for judging an abnormality and issuing a warning signal and also zero point and gain correcting circuits when operating the flowrate on the basis for the signal being output from the flow sensor in the case that the flowrate signal higher than the preset flowrate is to be input only from the flow sensor side and in the case that the flowrate signal higher than the preset flowrate is to be input only from the flow sensor side and in the event that the flowrate signal lower than the preset flowrate is to be input only from the fluidic element side.
