Authorized billing companies access the data logger remotely.
1.1.2 Pulse Meter Transmitter
The pulse meter transmitter (PMT) is a one-way end device that uses a
meter's standard pulse or reed-switched output. As meter counts
consumption, resulting pulses or switch closures are counted by the PMT. The
PMT then transmits the data via the commercial mesh network.
The PMT:
• Accepts data from the water meter
• Transmits the data to the repeater or receiver
• Is self-monitoring
• Is primary battery powered, with an easily replaceable battery
1.1.3 Repeater
The repeater is an optional component of an Inovonics system that expands
the mesh network’s coverage area. Repeaters can be easily included in the
initial installation, or added as the system grows.
The repeater:
• Receives messages and retransmits them at high power
• Optimizes communication paths to effectively manage RF traffic
• Retransmits messages to other repeaters, extending site coverage
1.1.4 RF Gateway
There are several kinds of RF gateway used in Inovonics systems, depending
on the application. TapWatch uses an EN4000 serial receiver to decode
EchoStream signals from EchoStream end devices and repeaters, and/or an
FA403 receiver to decode Frequency Agile (FA) signals from FA end devices
and repeaters, and outputs the data to the data logger.
The EN4000 and FA403:
• Listen for transmitted signals from end devices and repeaters
• Output data in a defined data stream to the data logger
