The E-Coder® is Neptune’s high-resolution solid state absolute encoder register. The E-Coder features a custom integrated-circuit design that digitally encodes the rotation of the measuring chamber, providing “absolute” registration with no internal battery requirement. The E-Coder functions in two modes: E-Coder BASIC and E-CoderPLUS.

The E-Coder BASIC mode functionality is the same as ProRead™ (ARB® VI), featuring programmability
up to a 10-digit ID number, three user characters, and 3-6 digit meter reading. In addition to the meter reading, the E-Coder provides a visual readout on rate of flow every twelve seconds when the LCD display is activated. When
connected to Neptune’s R900® or R450™ radio frequency MIUs, the E-Coder automatically operates in E-CoderPLUS mode, providing a high-resolution, 8-digit remote meter reading, and value-added features including leak, tamper, and reverse flow detection. True point-of-use leak detection is provided by monitoring a 24-hour period in fifteen-minute intervals. Tamper
detection is provided by reverse flow detection and monitoring the number of days of zero flow over the previous 35 days.

The E-CoderPLUS features are communicated through the E-Coder protocol, allowing host software platforms to interpret the data and pass the information directly to billing packages, CIS screens, and operational and maintenance reports. The E-CoderPLUS features enhance customer service and improve operational efficiencies for water utilities.

The E-Coder is available in two different configurations – inside set meters and pit set meters. For inside set applications, the E-Coder is housed in our plastic encoder register housing with terminal screws. For pit set applications, the E-Coder is housed in a glass lens and copper can enclosure with factorypotted wire connections.
