Adopt above-mentioned two kinds of modes control remote control valve 8 to make the gas use safe and reliable more.
The remote control valve 8 is arranged at the inlet end or the outlet end of the base meter 1 and is a detachable and connectable electric valve or electromagnetic valve. Adopt external remote control valve 8's mode, the threading of punching on having avoided current integrated form intelligent gas table base table 1, except that one more needs sealed point, avoid built-in remote control valve 8 to bond to fix in the base table that is full of the gas, do not get rid of built-in base table 1's remote control valve 8 because of the motor short circuit generate heat and the sealed possibility that became invalid, or bond the remote control valve in-process bonding fixed a little and have the irregularity, and influence the explosion-proof performance sealing performance of whole table, thereby the potential safety hazard brought.
