Metering

Head-end, meter data and prepayment vending systems.

AMI software that reads your meters, manages their data and sells prepaid credit, integrating with your billing and customer systems. The prepayment vending system is STS6 certified.

The range

A complete AMI software suite for smart and prepaid metering: a head-end system to communicate with meters, meter data management to store and use the data, and a prepayment vending system to sell credit. Each part works with open standards and standard interfaces.

Head-End System

The head-end system is the control centre of the AMI network. It reads meters and concentrators on schedule and on demand, sends commands such as remote connection and disconnection, manages firmware upgrades and time synchronisation, and flags alarms and events as they arrive.

Meter Data Management

Collected data is held in a central repository, validated, and estimated or edited where readings are missing. It is turned into reports such as load profiles, reading success rates, power quality and line loss analysis, and shared with your other systems through standard interfaces.

Prepayment Vending Management System

Sells and manages prepaid electricity. Credit is sold online or offline and loaded to the meter as an STS token, or sent remotely in online prepaid mode. The system is STS6 certified, and manages vendors, vendor credit, tariffs, deductions and meters.

Billing and Customer Systems

For postpaid customers, meter data feeds billing and collection. The systems integrate with your customer, billing and enterprise resource planning systems through standard interfaces, so you keep the systems you already run. A billing system is also available.

Multi Utility Metering

Electricity, water and gas meters can share one two way smart network, so a single system serves all three utilities.

Meters and Networks

The systems work with the meters and communication technologies in our range, from prepaid and smart single phase and three phase meters to power line, RF mesh, LoRaWAN and cellular networks. See meter communications and gateways for the network options.

Specifications

Design and performance

One system from the meter to the bill, built on open standards.

One System from Meter to Billing

The head-end system, meter data management and vending work together, so readings, tokens, tariffs and customer records stay consistent from the meter to the bill.

Open Integration

Standard interfaces let the systems exchange data with your customer, billing and enterprise systems, so you can add AMI without replacing what you already use.

Online and Offline Vending

Credit can be sold online, or offline where connectivity is limited, and delivered to the meter as a token or remotely, so prepaid customers can recharge in the way that suits them.

Flexible Tariffs

Single, step and time of use tariffs, with debt recovery and fixed charge schemes, can be configured and changed without touching the meter.

Secure by Design

STS token encryption, SSL/TLS, encrypted key data and intrusion prevention protect credit, customer data and meter commands.

Remote Management

Firmware upgrades, time synchronisation, device setup and alarm handling are done from the head-end system, so far fewer site visits are needed.

Reports to Suit

Reports can be customised to your requirements, with query filters, graphs and data lists for operations, revenue and network teams.

Sourcing and quality assurance

Our AMI software comes from an established metering manufacturer that designs its head-end, meter data management, prepayment vending and billing software together with its own meters, communication modules and gateways. The prepayment vending system is STS6 certified, and the manufacturer's AMI systems have been delivered on utility rollouts of hundreds of thousands to over a million meters. Delstar checks each order against your specification and delivers across New Zealand, Australia and the Pacific.

Lifecycle support

  • Specification and selection: we help match the head-end, meter data and vending software to your meter population, communication networks and existing billing systems.
