CHEKKER
Index for membrane gas meters
CHEKKER is a patented meter that generates a two-digit control number in its index. The number is generated mechanically and the system requires no maintenance. This control number is coded. When the meter is read, a control number is registered, which, with the help of a software module, allows the user to check whether the meter reading is correct or incorrect. To do this, the control number is automatically decoded before the billing system processes the data
