How to Choose AMI Software for a Water Utility
2026-09-17Advanced Metering Infrastructure gives water utilities something traditional meter reading cannot: a continuous operational view of consumption, meter status, network health, and abnormal usage. Instead of waiting for the next scheduled read to discover a problem, utilities can use interval data and alerts to investigate unusual consumption much earlier.
The value of AMI therefore extends beyond billing. A well planned system can support water loss management, accurate billing, faster customer service, and better network visibility. The important question is how meter data moves from the field into daily utility decisions.
Mainlink’s smart utility metering solutions combine ultrasonic meters, communication infrastructure, AMI software, and mobile apps for residents and installers. This article explains how AMI works, how it differs from AMR, where the operational value comes from, and what utilities should evaluate before starting a rollout.
Key Takeaways
- AMI is most valuable when meter data is used for operations as well as billing, including leak detection, water loss analysis, network monitoring, and customer service.
- The difference between AMR and AMI is broader than read frequency. AMI connects meters to a persistent communications and data environment that supports monitoring, alerts, analytics, and system integration.
- A pilot in one district metered area can help a utility validate coverage, data quality, water balance methods, and integration requirements before expanding across the network.
- Difficult sites are as much a hardware question as a protocol question.
- Mainlink is most relevant to utilities that want meters, connectivity, software, mobile apps through one provider.

What is AMI for water utilities?
AMI is a connected metering infrastructure that automatically and remotely transfers consumption and device data from meters to a central software environment. Depending on the meter and communication architecture, it can also support remote configuration and other two way functions.
In practice, AMI usually includes smart meters, a communications network, data management software, and integrations with utility systems. Customer applications and installer tools may also be included.
Mainlink’s data management platform combines Head End System and Meter Data Management functions in one environment. It collects and validates readings, monitors devices, supports water balance analysis, prepares billing data, and connects with external systems through an API. The platform runs on AWS cloud infrastructure.
AMR vs AMI: what actually changes?
Automated Meter Reading mainly reduces the effort required to collect meter readings. Advanced Metering Infrastructure goes further by creating an ongoing connection between field devices, communications, software, and utility workflows.
| Dimension | AMR | AMI |
|---|---|---|
| Primary purpose | Remote or automated meter reading | Connected metering and operational data management |
| Communication | Commonly one way | Commonly supports ongoing communication and, where configured, two way functions |
| Data frequency | Depends on the collection method and device | Supports frequent interval data according to system configuration |
| Main use | Billing and meter reading efficiency | Billing, alerts, water loss analysis, device monitoring, customer service, and planning |
| Field activity | Reduces manual reading effort | Can also reduce routine investigation by directing teams toward specific alerts or problem areas |
| Integration | Often focused on meter reads | Typically connects metering data with billing, analytics, and other utility systems |
If AMI is compared with AMR only on meter reading labor, much of its operational value is ignored. A stronger business case also considers water loss, estimated bills, investigation time, service calls, and data availability.
Where does the operational value of AMI come from?
The first area is measurement. Ultrasonic meters have no moving measurement parts, which reduces the mechanical wear associated with traditional meter designs. Mainlink’s QALCOSONIC W1 ultrasonic water meter is designed for low flow sensitivity and remote data collection.
The second area is abnormal consumption. Frequent data makes it easier to identify continuous flow, sudden changes, bursts, freeze events, reverse flow and other patterns sooner than a periodic billing read would allow.
The third area is customer service. Central consumption history helps staff investigate billing questions by using actual usage data rather than relying solely on a current read or estimate. AMI can also show which devices have stopped communicating, helping teams distinguish missing data from reduced consumption.
The fourth area is planning. Hourly, daily, and seasonal consumption data let a utility see when and where demand peaks, which supports network operation decisions and longer term infrastructure planning rather than only monthly revenue reporting.
How does AMI support non revenue water management?
A district metered area is a hydraulically defined part of the distribution network where inflow can be compared with recorded downstream consumption. The resulting imbalance gives the utility a smaller area to investigate.
It is important not to treat every difference as a physical leak. Non revenue water can include real water losses, apparent losses caused by meter or data issues, and authorized consumption that is not billed.
The American Water Works Association provides Free Water Audit Software for conducting a top down water balance and assessing water loss performance indicators. The current release is version 6.1, published in 2025, which carries the version 6.0 functionality and adds a carbon calculator. AMI does not replace that accounting framework. It improves the volume, frequency, and traceability of data available to support it.
Mainlink’s platform includes DMA monitoring, leak alerts, data outage detection, and network health analysis. Together, these tools can help utility teams identify where an imbalance is occurring and whether missing or unreliable data may be contributing to the result.
Which network should a water utility choose?
There is no single communication technology that is best for every deployment. Mainlink offers utility owned LoRaWAN infrastructure built on its own indoor and outdoor gateways, and its platform is hardware agnostic. Its deployments include LoRaWAN communication.
LoRaWAN can suit utilities that want to operate their own network and control gateway placement. Long range also matters for rural and regional utilities, where a small number of gateways can connect meters spread across a large service area at lower communication infrastructure costs than a per device carrier model.
The decision should be based on field conditions rather than protocol preference. Underground chambers, basements, terrain, building materials, reporting frequency, antenna placement, and local network coverage can all affect performance. A coverage test at the most difficult meter locations should happen before a utility commits to a network design.
What does a live Mainlink utility deployment show?
Mainlink’s Bernkastel-Kues utility case study describes a German utility that transitioned from a Wireless M-Bus setup to an NB-IoT smart metering system.
The project had 1,500 Axioma ultrasonic meters installed, with about 4,000 planned by the end of 2026. Mainlink reports more efficient billing, earlier leak detection in public buildings, faster responses to customer inquiries and improved resident access to consumption information.
These results are useful deployment evidence, but they are vendor reported rather than an independent audit of savings.
Four questions to answer before an AMI tender
- What is the utility’s current water loss position, and how reliable is the underlying water balance?
- Which part of the network can be used as a practical pilot area or district metered area?
- Which meter locations present the greatest communication challenge?
- Which integrations and meter functions are mandatory from the first phase?
Frequently asked questions
What is the difference between AMR and AMI for water utilities?
AMR primarily automates the collection of meter readings. AMI creates a broader connected infrastructure that supports frequent data collection, alerts, analytics, device monitoring, and integration with utility systems. The exact communication frequency and available remote functions depend on the system configuration.
How does AMI help reduce non revenue water?
AMI gives utilities more frequent consumption and system data. When combined with district metered area monitoring and a structured water balance, this can help identify abnormal differences, localize investigations, detect leaks earlier, and distinguish water loss from communication or data quality problems.
Can AMI work with meters a utility already owns?
Yes. Compatibility depends on the existing meter and its available outputs. Mainlink offers pulse converters that can connect compatible mechanical meters to a LoRaWAN based data collection system, which can support phased modernization without replacing every meter at once.
Next step
A practical AMI project starts with a defined operational problem, not a meter count. One pilot area, a current water balance, difficult installation sites, and clear integration requirements are enough to test the architecture before a wider rollout.
For utilities evaluating Mainlink, the next step is to compare those requirements with the meter, network, platform, and integration options available for the project.
