Transmitter Styles

This section describes the two different TRICON transmitter styles.
Digital Pulse
The original Digital Pulse model is a three-terminal transmitter that 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 five-terminal transmitters that 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.
Neptune produces the Digital Pulse model TRICON/E transmitters in only two styles for use
with ALL Neptune disc meters or ALL Neptune turbine meters, respectively:
Disc.
l
Turbine.
l
However, the Analog 4-20mA model TRICON/E transmitters are manufactured specifically for
the size and type of meter with which they should be used. For this reason, take special care
to ensure that you have the proper Analog 4-20mA model TRICON/E required for your
application. Contact Neptune for technical assistance.
Analog 4-20mA
The Analog 4-20mA model is a five-terminal transmitter that 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 digital signals.
