Remote Shut-Off Valve Solution
Turn meter data into controlled action. Mainlink’s AMI platform gives utilities and submetering providers governed, remote control over the Axioma ultrasonic meter’s integrated shut-off valve – no second device, no second installation, no truck roll.
Why Remote Shut-Off Valve Control Matters
Remote shut-off valves aren’t a new idea – smart valves have existed for years. What separates an effective remote-control solution from a basic one is how the valve, the meter, and the control workflow work together.
Leak detection alone tells a utility or property team that something is wrong but it doesn’t stop the water. Traditionally, someone still has to coordinate site access, travel to the property, locate the correct unit, and manually close a valve and while that happens, water keeps flowing and damage keeps growing. Most AMI systems report what happened and they rarely help a team act on it.
Mainlink helps close that gap. Together with its sister company, Axioma Metering, it has developed a smart water solution that combines metering, leak visibility, and remote valve control. Every remote action runs through Mainlink as a governed process from trigger to verification to record-keeping. That distinction matters for three groups in particular:
- Water utilities gain a compliant way to manage non-payment, contain leaks and bursts at the source, and cut emergency truck rolls.
- Submetering companies can offer a differentiated, higher-value service on top of existing meter-reading and leak-alert offerings.
- Property managers get faster turnover management and fewer unnecessary site visits across multifamily and commercial portfolios.
The result is fewer unplanned site visits, lower field-response costs, faster action when service needs to change, and more field-team capacity for the work that actually requires a visit.
One Solution, Built to Integrate and Scale
An Axioma Metering ultrasonic meter with an integrated remote shut-off valve. One device, one installation, no separate valve hardware to manage.
Connectivity
Available with LoRaWAN®, NB-IoT (CoAP), and wM-Bus (433/868 MHz OMS T1) communication for Europe and LoRaWAN® for North America.
Mainlink AMI platform
Monitors meter readings, leaks, device health, and valve status. Authorized users remotely control valves and keep a traceable history of every action.
Where Remote Shut-Off Control Makes a Difference
Leak and burst containment
Remotely isolate water at the unit when abnormal consumption or a potential leak is detected, limiting water loss and property damage before a crew arrives. Particularly valuable in multifamily buildings, where one leak can affect several units.
Non-payment management
Where local regulation and utility policy permit, remotely restrict or restore service after payment. Flow restriction offers a middle-ground option when a complete shut-off isn’t appropriate.
Turnover and vacancy management
Control water service during move-ins, move-outs, account changes, and vacancies without automatically dispatching a technician, restore service remotely when needed.
Maintenance and emergency access
Allow authorized property or service teams to isolate and restore water without first locating or accessing a manual shut-off valve.
Seasonal and freeze protection
Remotely close water service for vacant or freeze-exposed properties, reducing emergency travel and potential damage.
Controlled service restoration
Restore supply after an incident or payment without a site visit.
From Detection to Verified Action: How The AMI Platform Works
Remote control in Mainlink’s AMI platform is managed as a governed process, not a single command:
Operational trigger → Authorize action → Send valve command → Verify valve status → Record result → Restore service after payment
If a command fails, the platform flags it rather than assuming it succeeded. Every action is logged with who initiated it and when – built for audit-readiness, not just convenience.
Key features:
- Abnormal flow detection – burst or leak alerts reach the platform in real time, with no waiting for the next scheduled read.
- Mass valve closure – send a downlink command to multiple devices at once; the same authorize/verify/record process applies whether it’s a single service or a few hundred.
- Payment status monitoring – the platform tracks customer debt status and notifies the moment a payment is due.
- Flow restriction – if a customer balance stays negative, flow can be restricted according to each utility’s policy rules, as an alternative to a full shut-off.
- Listening window enablement – on a critical alert, the meter immediately opens a frequent listening window to receive downlinks from the platform.
- Abnormal flow threshold correction – the platform adjusts device thresholds automatically based on data and consumption patterns.

Ultrasonic Meter With an Integrated Shut-Off Valve
The QALCOSONIC W2 is an ultrasonic water meter with an integrated smart valve, designed for accurate cold and hot water measurement in households, apartment buildings, and commercial premises.
Application highlights:
– Static (no moving parts) ultrasonic flow measurement for long-term stability and reliability
– Eliminates measuring deviations caused by sand, suspended particles, or air pockets
– Sensitive and accurate at low flows, down to 1 l/h
Failsafe mechanism prevents valve closure when energy is insufficient
– Programmable physical button, configurable by volume (liters) or time
– Daily consumption mode with a configurable usage limit (1–65,000 liters)
– Configurable partial valve position
– Ready for AMR with NFC, wM-Bus, LoRaWAN, and NB-IoT

Frequently asked questions
A smart water meter with an integrated shut-off valve is an ultrasonic water meter that combines accurate water consumption measurement with remote water supply control in a single device. The integrated valve allows water supply to be remotely turned on, shut off, or restricted through a connected smart metering platform, without requiring physical access to the meter.
Yes, via Mainlink's AMI platform.
Yes it can.
Yes, utilities can control many valves at once.
