TRICON ®/ Installation and maintenance of E/E2/E3 transmitters

Product Overview

core functionality

For Neptune ®  The series of water meters provide electronic interfaces for water consumption monitoring and support various process controls based on water consumption, which can be integrated with SmartTrol ®  Integrate controllers or third-party instrument devices to build complex measurement and monitoring systems.

Product Model and Classification

Divided by signal type

Digital Pulse

Basic model: 3-terminal design, outputting electrical pulses corresponding to water flow rate, requiring 12-24VDC power supply, suitable for scenarios that only require digital signals.

E2/E3 models: 5-terminal design, retaining basic features, new high-resolution output terminal and counting direction terminal, supporting high-speed bidirectional counter connection, also requiring 12-24VDC power supply, suitable for high-resolution digital signal demand scenarios.

Adaptation types: divided into two categories: Disc specific and Turbine specific, which can adapt to all Neptune disc or turbine watches.

Simulate 4-20mA type

5-terminal design, with digital pulse type basic functions, providing additional 4-20mA analog signal output proportional to water flow rate, requiring 24VDC power supply, suitable for scenarios that require both analog and digital signals.

Adaptation requirements: Strictly match the size and type of the water meter, confirm the compatible model when purchasing, and contact the manufacturer for technical support if necessary.

Special Model Description

The TRICON/E3 transmitter is not submersible and is not recommended for pit installation scenarios.

The T-8 disc gauge has been discontinued. Currently, all TRICON/E transmitters compatible with disc gauges are T-10 type. When compatible with T-8 gauges, it may not be possible to achieve a 20mA output level. The relevant values are only for calibration reference.

Note: The high-resolution output of TRICON/E2 requires multiplying the number of pulses per gallon and the maximum flow pulse output value by 36, and E3 requires multiplying by 40

Note: The high-resolution output coefficient is the same as the T-10 table; When the T-10 transmitter is adapted to the T-8 meter, the theoretical flow rate corresponding to the 20mA output is greater than the maximum allowable flow rate of the water meter, which cannot be achieved in actual operation
