Quick Install Guide

1: General Instructions

The E-CODER®is an electronic absolute encoder
register designed for use with Neptune's Automatic
Reading and Billing (ARB®) System. This register
operates with Neptune's R900®and R450™ MIUs,
providing advanced features such as leak, backflow,
and tamper direction.

With the E-CODER register, both the homeowner and
the utility can use the following features:

l Nine-digit display for visual reading

l Eight digits for billing

l Water flow indicators

l Intermittent and continuous leak detection icon on

the LCD panel

This guide helps you identify and read information
displayed on the E-CODER register. It also helps you
recognize the common causes of leaks and instructs
