Abstract

PURPOSE: To secure an easy visual recognition whether the effective using quantity of the meter is within the limit range by providing the alarm display panel, which operates when the effective using quantity is exceeded and can be viewed through the display window, at the lower side of the display window provided to the scale display panel.
CONSTITUTION: In the case of the water meter in which circular scale 8 divided into 10 equal parts is provided to scale display panel 7, all pointers 6 indicate zero at 1000m3 if the minimum unit of the scale is set to 1. Thus the fact is known that the meter display had one circulation. In case the effective using quantity is set to 3000m3, alarm display panel 8 is turned when the scale display has three circulations. And red-color part 8b can be viewed through display window 10. Accordingly, if the range of part 8b is secured more than three times as large as white-color part 8a, the alarm display is kept for a while and never returned to part 8b. In such way, an easy visual recognition is secured whether the using quantity is within the limit of the effective using quantity.
