Applying and programming these types of registers correctly for the appropriate meter size
can greatly enhance billing accuracy. Instead of the previous meter reading examples in
which multipliers of 10 are used to create zero billing digits at the end of the actual read
digits, these meters can provide greater resolution. This results in an increase in billing
accuracy.
With the given scenario on the previous page (100-cubic foot increments), we recommend
using four-digit, hard-wired meters for all small meters, since only four digits are required to
obtain the appropriate billing unit accuracy. We also recommend using six-digit, hard-wired
meters on all intermediate and large meters. The intermediate meters can be programmed
to return five digits, and the large meters can be programmed to return all six digits.

VII) Electronic Digital Register
The E-CODER
®
is an electronic digital encoder register that has a proprietary integrated circuit
that provides absolute registration with no internal battery requirement. The E-CODER
functions in two modes: E-CoderBASIC and E-CoderPLUS. The E-CoderBASIC mode
functionality is the same as ProRead featuring a programmable ID number (up to 10-digits),
three user characters, and three-digit to six-digit meter reading.
When connected to Neptune's R900
®
v2 radio MIU, the E-CODER operates in E-CoderPLUS
mode providing a high-resolution, eight-digit meter reading and value-added features
including leak, tamper, and backflow detection.
Example: Nine-digit LCD displays the meter reading in billing units of gallons or cubic feet.
