制御装置は必要でなく、圧力低下表示装置を追加すれば
従来の制御装置を利用できるメリットがある。As described above, according to the present invention, the pressure drop signal can be transmitted by using the control line for connecting the gas switch and the control device, which is conventionally wired instead of the dedicated signal line. Because it can be done, the economic effect is great. Further, there is an advantage that a conventional control device can be used if a pressure drop display device is added, since a dedicated control device is not required.
