Prepaid metering portfolio

Conlog specialises in prepayment solutions and therefore our metering product range is one of the most
comprehensive in the industry. Customers are able to select from single phase devices for the residential sector, through to three phase devices for light industrial applications. We also offer a variety of metering footprints, to enable cost effective solutions for the deployment of prepayment into both new and retrofit environments.

Standard features:

All our meters are manufactured to the highest quality standards and are STS approved. In addition, all meters are available with:

  • Class one or Class two accuracy
  • Enhanced tamper detection
  • Reverse energy detection and measurement
  • Delayed reconnection
  • Programmable under and over voltage trip
  • History of tokens entered into the meter
  • Variety of consumption information
  • Consumption rate indicator

Meter footprints

ServicesMost meters are available in a variety of different installation footprints, the most common of which are mentioned here:

DIN rail

A DIN rail is a standard type of metal rail that is widely used for mounting circuit breakers. This is a popular footprint for prepaid meters as many meters can be installed together in one enclosure. The term DIN derives from the original specification published by Deutsches Institut fur Normung (DIN) in Germany, which was then adopted worldwide.

BS footprint

Previously referred to as British Standard, this is traditionally used for retrofitting an existing conventional meter, and refers to the wiring of the terminal block as well as the three mounting screws. Our prepaid meters are equipped with a BS terminal block, making them ideal for retrofit installations.

Common base

Designed by Conlog and now an industry standard, the common base footprint comprises of two parts; a wallbase and the active meter. This configuration allows for the pre-installation of the wallbase and the meter can be clipped into the base when the meter installation is required.


Split / Combo



Conlog’s split metering technology comprises a metering device and a keypad. The meter is installed outside the premises, whilst the consumer has a keypad installed inside the property. With this solution, the intelligence is housed within the meter, whilst the customer keypad simply reads data from the meter. In order for the two devices to communicate, there are two options available to customers:

Wired solution

A two core cable, or twinflex, is used between the meter and the customer keypad.

Wireless solution

The meter and consumer keypad communicate via radio frequency, on the internationally open and accepted license free ISM (Industrial, Scientific and Medical) band.


A combo meter is a term used to describe an installation whereby the meter and keypad are combined in a single unit. The meter is installed in the consumer premises, usually next to the distribution board. These meters are available in single phase and three phase variants.

Wired and Wireless combos

post paid



Conlog meters are configured as pre-paid meters by default, however the (09) range can be configured to operate in either the pre-paid or post-paid mode.

In the pre-paid mode, all accounting functionality is as per standard pre-paid requirements.

In the post-paid mode, the meter operates as a credit meter, meaning the consumer would have to have the meter read and be billed in a conventional manner. Pre-paid accounting functionality is not available whilst in post-paid mode.

The benefit for the utility is the added flexibility to the consumer. The consumer can be switched from a post-paid mode to pre-paid mode with just an encrypted token. In addition, a consumer who previously used conventional meters can still make use of post-payment and can still be switched to a pre-paid mode if required.
