Abstract:
PROBLEM TO BE SOLVED: To separately measure use amounts of gas of a regular charge and a special charge with a single meter required to be verified, by setting a single display part for selectively displaying, by a switching means, values measured by a first measurement part measuring the regular charge and a second measurement part measuring the special charge.
SOLUTION: A gas supplied to a first gas measurement part 10 is sent to a gas consumption facility system I of a regular charge and also sent to a gas consumption facility system II of a special charge through a second gas measurement part 20. The first gas measurement part 10 is a normal gas meter required to be verified, and the second gas measurement part 20 is a gas meter accompanying and integrally provided with the first gas measurement part 10 and not required to be verified. The first gas measurement part 10 has an integrated value display part 11 and a display change-over switch 12. When the switch 12 is pressed, the display part 11 displays an integrated value of the first gas measurement part 10 or an integrated value of the second gas measurement part 20.
