TRICON/E/E2/E3 Transmitter Installation and Maintenance Guide
The TRICON ® transmitter provides an electronic interface to Neptune water
meters, enabling customers to monitor their water usage and control various
processes based on that usage. The TRICON transmitter is available in two
styles, Digital Pulse and Analog 4-20mA.

Digital Pulse

The original Digital Pulse model is a 3-terminal transmitter which outputs
electrical pulses at a rate corresponding to the rate of flow through the meter. It
requires 12-24VDC operating power and is intended for use in applications
requiring only a digital signal.
The TRICON/E2 and TRICON/E3 Digital Pulse models are 5-terminal
transmitters which have the same features as the original Digital Pulse model
plus two additional terminals (High Resolution Output and Count Direction)
for connection to a high-speed, bi-directional counter. It requires 12-24VDC
operating power, and is intended for use in applications requiring a high-
resolution digital signal.

Analog 4-20mA

The Analog 4-20mA model is a 5-terminal transmitter which has the same
features as the original Digital Pulse Model, plus two additional terminals for a
4-20mA output that is proportional to the rate of flow through the meter. It
requires 24VDC operating power, and is intended for use in applications
requiring analog and/or digital signals.
All models are designed to be mounted between the meter maincase and a
totalizing register, and they do not affect the normal operation of either the
meter or the register. When used with a Smartrol
party instrumentation equipment, both models allow monitoring and/or
controlling complex metering systems.
