01 / Understand the meter
Start with what the meter actually does
The AquaFlow LXC is an ultrasonic smart STS split water meter for cold-water applications. It is available in 15 mm and 20 mm sizes, uses Class D ultrasonic measurement, supports horizontal or vertical installation, and combines metering, credit control and an integrated ball valve in one secure meter body.
The AquaFlow LXC measures water without moving mechanical measuring parts. In prepaid operation, the meter tracks the available STS credit and uses its integrated valve to control water supply. A separate wireless CIU lets the customer enter credit and query selected meter information, while optional Sigfox, LoRaWAN or NB-IoT communication can be selected for smart metering projects.
02 / How it works
How the AquaFlow LXC works
Follow the water, measurement, credit and customer-interface path through the system.
02
Ultrasonic measurement
Dual-path transit-time ultrasonic measurement calculates water consumption without moving mechanical measuring parts.
03
Credit is managed
In STS prepaid operation, purchased credit is stored and the remaining water credit is tracked in cubic metres.
04
The valve controls supply
The integrated motorised ball valve provides controlled disconnection and is also used by supported protection and tamper functions.
05
The customer uses the CIU
A separate wireless Customer Interface Unit is used to enter 20-digit STS credit tokens and query selected meter information.
06
Optional smart communications
Depending on the selected configuration, the meter can use communication modules such as Sigfox, LoRaWAN or NB-IoT for smart metering applications.

Function explained
Dual-path ultrasonic measurement
Transit-time ultrasonic technology measures water without moving mechanical measuring parts and is designed for low pressure drop and low maintenance.

Use the real product and installation visuals to understand how the meter, customer interface and smart-metering pathway fit together.
Meet the CIU
The CIU is the customer's interaction point for supported token entry, balance enquiries and meter information.

Use the installation image to understand the physical context in which the meter is fitted and accessed.
05 / Where to use it
Match the meter to the property
A meter should be selected for its application, not simply because it is prepaid.
Homes and rental properties
Suitable for managed cold-water consumption where accurate measurement and prepaid control are required.
Apartment buildings and multi-unit properties
Useful for individual unit metering where customers need a separate CIU for token entry and balance information.
Small commercial premises
Suitable for small commercial cold-water applications requiring controlled consumption and reliable metering.
Challenging water-quality environments
Ultrasonic measurement is designed to be less affected by scale, build-up and sand than traditional moving-part measurement.
Smart metering projects
Optional communication modules support configurations for AMR and AMI projects.
06 / Selection guide
Should you choose this meter?
Use the requirements below as a practical starting point, then confirm the site-specific technical requirements before installation.
Choose the AquaFlow LXC when...
- You need an STS prepaid smart water meter with a separate customer interface unit.
- You want ultrasonic measurement without moving mechanical measuring parts.
- Your installation requires a 15 mm or 20 mm domestic cold-water meter.
- You need horizontal or vertical installation flexibility.
- An integrated ball valve is required for managed supply control.
- The project may require Sigfox, LoRaWAN or NB-IoT communication.
Check these points before ordering
- Confirm whether the installation requires the 15 mm or 20 mm version.
- Confirm the required thread size and available installation space.
- Confirm which communication module, if any, is required for the project.
- Confirm the preferred assembly option, such as above-ground, wall-mount or surface-mount configuration.
- Confirm the CIU location and practical wireless communication conditions on site.
- Confirm that the installation follows the required flow direction, pipe arrangement and non-return-valve requirements.
- Confirm the vending, STS configuration and system onboarding requirements before commissioning.

09 / Questions
Common questions about AquaFlow LXC
Is the AquaFlow LXC a prepaid water meter?
Yes. The meter supports STS prepaid operation with 20-digit credit tokens. The manufacturer manual also describes configurations for post-payment, billing, flow limitation, AMR and AMI.
How does the AquaFlow LXC measure water?
It uses dual-path transit-time ultrasonic measurement. The measuring system has no moving mechanical measuring parts.
What sizes are available?
The documented versions are 15 mm and 20 mm.
Can it be installed vertically?
Yes. The manufacturer documentation states that the AquaFlow LXC can be installed horizontally or vertically.
Does it have a shut-off valve?
Yes. A motorised ball valve is integrated into the meter for controlled disconnection and supported protection functions.
What is the CIU used for?
The separate Customer Interface Unit is used for STS token entry and for querying selected information from the paired meter.
Can the meter communicate with a smart metering system?
Yes, depending on configuration. The product documentation lists Sigfox, LoRaWAN and NB-IoT communication module options.
Is the meter suitable for outdoor meter locations?
The product data sheet lists the AquaFlow LXC meter body as IP68. The separate CIU is an indoor interface and has a different environmental rating.
Does it detect abnormal conditions?
The documentation describes battery alarms, dry-pipe indication, reverse-flow indication and multiple tamper conditions.
Is it suitable where water quality is challenging?
Yes. The manufacturer documentation describes the ultrasonic meter as insensitive to scale, build-up and sand and lists households, apartment buildings and small commercial premises with water-quality challenges as applications.
Understand it. Select it. Install it correctly.
