New productInzalo ultrasonic flowmeters
AquaFlow LXC: water uses the credit, air does not.
Ultrasonic prepaid water meters built for networks where supply is intermittent. The meter recognises air and dry-pipe conditions instead of billing every restart as consumption, and reports over NB-IoT without neighbourhood concentrators.

Flagship solutionInzalo AquaFlow LXC
Pay for water.
Not air.
When an empty pipeline refills, compressed air can arrive before a steady column of water. AquaFlow LXC is designed to recognise air-flow and dry-pipe conditions so prepaid credit follows water delivered.
- UltrasonicNo moving measuring parts
- STSOpen vending interoperability
- Class DHigh-accuracy measurement
- IP68Protected meter body
PIPE CONDITIONAir detected
PREPAID CREDITProtected
Why this matters
When supply returns, air can arrive first.
Across Zimbabwe—and anywhere water supply is intermittent—an empty main may carry compressed air and an unstable air-water mixture before normal flow settles. This is a wider network challenge, not a Harare-only problem; the public discussion in Harare provides a documented local case study.
- 01The line empties
Supply is interrupted and sections of pipe run dry.
- 02Pressure returns
Compressed air moves ahead of stable water flow.
- 03Apparent use can register
Some mechanical measuring systems may respond to the moving air.
- 04AquaFlow distinguishes the condition
Air-flow and dry-pipe recognition protect the integrity of prepaid measurement.
The AquaFlow difference
See what the meter sees.
Switch between the two pipeline conditions.
AIR / DRY-PIPE CONDITION
Air detected.
No water volume counted.
The meter identifies the abnormal pipeline condition rather than treating the restart as ordinary water consumption.
AVAILABLE CREDIT12.400 m³UNCHANGED
In plain language: air passes; the resident's credit stays protected.
The key difference
Water should use your credit. Air should not.
Across intermittent-supply networks, an empty pipe may refill with compressed air before stable water flow. AquaFlow LXC recognises air-flow and dry-pipe conditions so credit follows verified water delivered.
For residents: credit follows the water delivered.
For engineers: dry-pipe, air and reverse-flow indications support troubleshooting.
For utilities: explainable readings build confidence in prepaid billing.
NO IMPELLERNo wheel for air to spin.

How it measures
No wheel to turn. Sound does the measuring.
AquaFlow LXC uses dual-path transit-time ultrasonic sensing. It compares sound travelling with and against the flow, calculates delivered water volume, and recognises air-flow and dry-pipe conditions—with no moving measuring parts and no wheel for air to spin.
Built-in intelligence
More than a meter reading
Open vending standard
Keep the vending platform.
Upgrade the meter.
AquaFlow LXC is STS certified. It is designed to work with any correctly configured STS-compliant vending platform, allowing a utility to integrate the meter with its existing vending environment instead of creating a proprietary vending island.
Preserve customer familiarity
Continue using the recognised secure token-based prepaid journey.
Avoid supplier lock-in
STS interoperability supports compliant components from different suppliers.
Final integration remains subject to the utility's vending configuration, supply-group and key management, technical testing and implementation approval.

How customers load credit
The meter is paired with an in-home customer interface unit (CIU). Customers enter standard 20-digit STS tokens, and the meter loads the credit in cubic metres.

Installation configurations
Field-ready. Public-space protected.

Zimbabwe deployment model
No concentrators. No neighbourhood network to maintain.
AquaFlow LXC supports replaceable communication modules for NB-IoT, LoRa, LoRaWAN and Sigfox, allowing each local authority to select the network that fits its coverage, infrastructure and operating model. For the current Zimbabwe proposal, Lonsburry is prioritising NB-IoT.
Why NB-IoT now
Use the cellular network already in the field.
NB-IoT is a low-power cellular technology designed for connected devices that exchange small amounts of data. Each enabled meter communicates through a participating mobile operator's existing network and carries readings, status and alarms towards the utility's approved head-end system. Because the route does not rely on utility-installed neighbourhood data concentrators, the authority avoids having to install, power, secure and maintain a separate field communications layer. That can lower infrastructure cost and make expansion from a pilot to a wider meter estate simpler.
- AquaFlow LXC meterSends readings, status and alarms
- Participating mobile operatorExisting NB-IoT cellular infrastructure
- HES platformMonitor, report, investigate and act
Meter to mobile network to HES—without a field data concentrator between them.
Removes a separate neighbourhood gateway layer from the proposed communications path.
Can reduce equipment, power, site-security and maintenance costs associated with concentrator networks.
Low-power cellular communication suits periodic meter readings, status updates and alarms.
New enabled meters join the operator network rather than waiting for a new local collection point.
Deployment flexibility
One meter platform. Four communication choices.
The communication module is selected to suit the local authority's coverage, network strategy and approved systems. NB-IoT is the preferred route for the current proposal; the other supported configurations remain available where they are the better local fit.
Final selection and service design remain subject to local coverage, the authority's architecture, commercial agreement, regulatory requirements, active connectivity and approved HES integration.
Head-End System
Every meter in the field. One operational picture.
The HES turns thousands of connected meters into a manageable utility network. Teams can see which meters are active, find exceptions, review consumption history, investigate events and produce operational reports from the office.
From field data to utility action
Know what is happening before a complaint reaches the counter.
In the proposed NB-IoT deployment, the participating mobile network supplies the communication path. The HES organises incoming information into useful views for engineering, revenue, customer service and management teams.
