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.
