GEM supplies high quality meters that meet both local and international standards. Our certified meters have the following features:

Measure of Electricity Consumption

Our meters measure electricity consumption active power such as kWh, reactive power – kVarh and maximum demand -kW with high accuracy class 2 or 1.

High Accuracy

We also provide meters that measure electricity consumption active power -kVarh and maximum demand-kW with accuracy class 1, 0.5 or 0.2 with high stability.

Customer Self –Service

Our pre-paid metering systems allow consumers to buy credit directly unto their card from the vending centres without the need to visit the electricity utility centre to settle their bills.

Tamper Proof

GEM’s meters accurately detect tampering such as meter bypassing, load connection and illegal opening of meter or terminal covers as well as any adjustments to meter rated power.


Our meters are capable of calculating energy in multiple tariff environments (up to 8 tariffs in 4 different seasons), and can perform maximum demand calculation with or without automatic reset and memory.

Meter Data Collection

The metering system enables a two-way communication environment for sending and receiving data to and from the meters. Examples of data that can be communicated are meter consumption, load profile, maximum demand, tamper events and power quality.

Revenue Collection

Our meter system receives energy credit in advance and consumes it according to the different tariff schemes. This assures revenue collection for the service provider.

The different tariff schemes include:

Time of Usage (T.O.U. TARIFF) using up to 8 tariffs in 4 different seasons which are programmable.

Step Tariff using up to 8 steps per month which are programmable and Flat Tariff.

Network Losses Measurement

Our metering system is capable of measuring network losses per building, transformer, district, zone or city to detect bad connections as well as illegal ones.

Upgradable Meter Hardware

GEM uses a metering system hardware that can be upgraded to integrate new functionality and features without changing the meter.

Examples include:

  • Upgrading the meter from offline two-way communications to online communication through PLC, RF, and GPRS.
  • Upgrading the meter from manual reading to Automatic Meter Management System.
  • Adding new functionalities to the meter software by reprogramming the meter micro-controller (processor).

Peak Demand Monitoring

We supply meters that measure consumers’ peak demand and stores dates and times of exceeding the preset peak demand value of each consumer.

Load Limit Control

Our metering system is also capable of disconnecting power from consumers in case they exceed their maximum allowable load according to their contract. This is to avoid network overload in case of power shortage and this feature is programmable either through optical port or through two-way communication.

Auto Billing Process

Our systems also read energy consumption through a two-way communication system to prepare consumers bills without the need to visit them to read their meters.

On-line Control

Also, GEM uses metering systems that allow consumer data to be collected in an online communication environment.
