Basically ,Software is anything
that links the internal components of a device to the outside world .Since the
outside world does not have the access
to the internal components, also known as hardware therefore software has a big role to play in
linking the two. Every device requires
some or the other software for its proper working and functioning.
Electric Submetering System
has various softwares
embedded in them which make them useful for such wider applications. This software
includes Current Transformers, which measures
the current carried by the wire that passes through the center of the CT. They
come in different sizes to handle almost any current up to 1600 amps, Display
Counters with an LCD which will register a 50ms; 12 volt pulse can also be used
with any EZ Meter, and Automatic Meter Reading (AMR).
Automatic
Meter Reading Software in the EZ Meters can
implement 3 types:
- Pulsed Output
- Serial Communication
- None
In Serial Communication the meter
reports kilowatt hours as well as volts, amps, watts, power factor, phase
angle, hertz and polarity. The meters can be connected together either by a
wired network, a wireless network, or a combination of both. The meter network
itself can be connected either to a local computer, to a LAN, or to the
internet. Each meter has either an RS-485
port or an RS-232 port.
In Pulsed Output A third party pulse counting system such as the Inovonics
Tap Watch product line is needed, Because of which it is somewhat costly and is
used rarely. The downside to this type of AMR is that KWH is all you get. The
upside is that it can be installed as part of a system that includes water and
gas meters.
The none AMR is most widely used one as it is cheap and it rarely
breaks, but the downside is that it requires the manual reading of the billing
period and the number of KWH used.
