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.
CHAPTER INSTALLING THE TRANSMITTER This chapter is designed to take you through the installation process for the TRICON transmitter. T O O L S A N D M AT E R I A L S The following equipment is required for the installation: medium, flat-head screwdriver wire stripper hammer...
For longer runs (1,000’ maximum) use #22 AWG shielded twisted pair cable for signal connections, and tie the shield to ground at the receiving device, not at the TRICON/E transmitter. When forced to cross other wiring, cross at right angles to minimize noise coupling between wiring. Use a dedicated power source, such as a separate circuit breaker or isolation transformer, for all instrumentation equipment to reduce the effects of electrical noise from other equipment on the line.
Figure 2.2 Inserting Multi-Conductor Cable Figure 2.2 Inserting Multi-Conductor Cable Figure 2.2 Inserting Multi-Conductor Cable Strip the outer covering of the cable back approximately 1 ⁄ ” from the inserted end. Separate the individual conductors and strip the insulation back approximately ⁄...
Testing the Wires After wiring the transmitter, double-check to ensure it is wired correctly. Apply power to the TRICON transmitter and check the output signals as follows: At No Flow – there should be no pulses out of the digital output terminal, and a 4mA direct current should be present in the 4-20mA loop.
Refer to Figure 2.6 for assistance with the following steps. Figure 2.6 Mounting the TRICON Transmitter Twist the register approximately ⁄ turn counter-clockwise and remove it from the meter. Position the TRICON transmitter on the meter and twist it clockwise until it locks into place. Place the register mounting ring on top of the TRICON transmitter with the four rounded grooves facing upward.

CHAPTER MAINTENANCE If you find that your TRICON system is not operating as expected when installed, use the following guidelines to try to determine the source of the problem. T R O U B L E S H O O T I N G If the TRICON appears to be operating, but electronic flow indication does not agree with mechanical register indication, try the following: Verify that the TRICON and register match the meter size and type.
