ProMeter Features
Prepaid Metering.

Prepayment energy meters are a type of domestic energy meter that requires
users to pay for energy before using it. Tis is done via a recharge through the
supplier vendor. Tey work a bit like a prepaid mobile phones,
we have to top-up with balance to get our electricity. ProMeter
automatically cut the electrical supply using in-built relay circuit if the balance
is used-up.

All programmable parameters can be set to the meter using a centralized
computer based software ‘ProMeterSoft’ using RS485 communication
designed for vendor use. Te ProMeter can be programmed to compute the bill
on either KWh or KVAh consumption.

Supply Auto Cut.

When sufcient balance is available in the meter it will work uninterrupted and
will deduct the energy charges according to the energy tariff programmed.
When the balance reaches a marginal limit, programmed through the
ProMeterSoft, an alert via SMS or Email would be sent to the user. At this stage
the user should recharge the meter to enjoy uninterrupted supply. However, if
meter is not recharged till balance reaches zero then meter display will start
blinking and buzzer will blow in home display unit and meter will continue
operation in emergency credit limit 1. Te meter will cut supply when limit is
over. But, if utility provides emergency credit limit 2 then the meter will
operate in reduced load mode till the limit 2 exceeds. After limit 2 is crossed
meter will cut the supply permanently and will allow the operation only in
happy hours.

Emergency Credits.

ProMeter can cut the user supply when the balance reaches zero. Apart
from the normal balance the meter allows to program two emergency
credit limits, which works as follows:

• Emergency Credit Limit 1: Tis the limit up-to which the supply remains
uninterrupted unconditionally. Only a display warning and an audible alarm,
in case of home display unit, would be triggered.

• Emergency Credit Limit 2: After limit 1 the meter will operate in reduced
load mode. Till limit 2 the meter will allow the reduced load for emergency
services. In reduced load mode if meter exceeds the load sanctioned it will
operate in overload mode as explained earlier. After limit 2 the meter will
cut of the supply permanently.

ProMeter is supplied with an

elegant optional Home Display

Unit ‘Atom’. In case Atom is

installed then the display and

switch operation of the meter is

replicated on the Atom.
