Neptune Technology Group E-CODER PRODUCT SHEET

A PRODUCT SHEET OF NEPTUNE TECHNOLOGY GROUP

E-CODER® Solid State
Absolute Encoder

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
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
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.

KEY BENEFITS

Enhanced “customer care”

• Leak history/diagnostics

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 factory-potted wire connections.
