Transmitter Styles; Digital Pulse; Analog 4-20Ma; Usage - Neptune TRICON E Installation And Maintenance Manual

CHAPTER 1 OVERVIEW
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.
T R A N S M I T T E R S T Y L E S

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/E 3 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.
U S A G E
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 SmartTrol
®
controller or other third-party instrumentation equipment, both models allow monitoring and/or
controlling complex metering systems. The Digital Pulse model TRICON/E transmitters are produced
in only two styles: Disc and Turbine, for use with ALL Neptune disc meters or ALL Neptune turbine
meters, respectively. The Analog 4-20mA model TRICON/E transmitters, however, are manufactured
specifically for the size and type of meter with which they are to be used. For this reason, special care
should be taken to ensure that you have the proper Analog 4-20mA model TRICON/E required for your
application. Contact Neptune for technical assistance, if necessary.
