The Important of Meter Digit

In Customer Management System for Electric company, it is important that the system records meter digit.

Business process personnel from the company should decide whether they are going to tell the readers to read only the real number or until the decimal point. Example in the picture has meter digit 5.1 (5 digit real numbers and 1 decimal digit). This decision will impact on how the meter digit is stored in the system. If reader is going to read only the real number, then in example picture, reader will record only "00001" (without "4"). Also, the customer management system or billing system will only record 5 as meter digit.

Meter digit or sometimes called meter dials could be used by the system to detect meter turn over. Ok... what is meter turn over you may ask. Meter turn over is when the meter reaches its maximum number when registering kWh consumption. Let us say that you have a meter with 5 meter digit, when the previous reading is 99998 and the current reading is 00001, the system should detect that there is meter turnover and the consumption will be calculated as 3 kWh (99998 going to 99999, 99999 going to 00000, 00000 going to 00001) because the system knows that that meter can only reach up to 99999 and will be return back to 00000.

This can be also a good indicator for a company to trigger a service order to calibrate a meter.
