With the development of
modernized electronics, machines and equipments people have become more
dependent on them as they have lot of advantages to offer. One such example is
the development of Electric meters which are easy to install, maintain, read, purchase
and have Automatic Meter Reading system as well. Because of which these meters
are seen most prominently in the offices, apartments, marinas, industries and
RV parks etc.
These meters are
available online and have the system of
automatic electric meter reading. The meters posses three types of
Automatic Meter Reading i.e. Pulse Output,
Serial Communication and None. Each meter that uses serial communication AMR has an RS-485
port or an RS-232 port that can be connected to a wired or wireless network
because of which the ports are electrically isolated. This allows the
meter to register the kilowatt hours as well as volts, amps, watts, hertz and
polarity. The
Pulse Output AMR closes a dry contact
switch every time it notices a kilowatt hour and the pulse counting system
detects it, records it and transmits the total count to the data accumulator.
Since the data accumulator is costly, this type of AMR is rarely used. The None AMR is
most widely employed as it is cheap and non breakable.
The products of electric submeters are
made up of components that come with the warranty of surviving the voltage
shocks but do not provide warranty for withstanding the natural disasters such
as lightening strikes, physical damage, floods etc. The Electronic Module,
Current Transformers, Display counters etc is what makes an Electric Submeter.
