Abstract:
     The present invention relates to a capacity flowmeter with explosion-proofing structure and pulse signal generator. It can prevent the tested fluid from flowing into the pressure-resisting explosion-proofing chamber in which the flow pulse signal generator is received. It is composed of the following portions: main body box which has several cylinders respectively receiving piston; upper cover on which there is a top cover forming explosion-proofing chamber; shaft hole; through-hole which is positioned on side surface of shaft hole can ventilates with atmosphere; and driving shaft inserted into the above-mentioned shaft hole. Because the fluid to be passed through seal component and flowed into explosion-proofing chamber can be volatilized to atmosphere from the above-mentioned through-hole, so that the fluid cann't be flowed into the explosion-proofing chamber.
