TapWatch Overview
1.1 TapWatch Introduction
TapWatch is a submetering system that reads and collects utility meter reading
data. Already installed in millions of apartments nationwide, TapWatch helps
multifamily property owners increase their net operating income by having
residents pay individually for utilities they use.
Wireless technology allows for quick and easy installation of the TapWatch
system, with minimal disruption to residents. Drilling holes through walls,
running wire to each building, and digging trenches for cabling is not
necessary.
Inovonics created and introduced TapWatch in 1998. Based on 900MHz
spread spectrum wireless technology, this submetering system was created
specifically for the multifamily market. The power of 900MHz technology
allows hundreds of transmitters to send information to one receiver. Using
repeaters, a mesh network can be created to cover large or multi-building
properties.
1.1.1 How TapWatch Works
1. A pulse output meter installed in each apartment is connected to an
Inovonics pulse meter transmitter (PMT).
2. The PMT converts the meter reading into a digital signal and transmits it.
3. Repeaters placed at strategic locations throughout the site receive signals
from the transmitters, verify them, and amplify them for transmission to the
receiver.
4. The data logger decodes transmissions from the receiver and stores the
data for retrieval by TapWatch 3 software.
