Automated meter reading for IoT smart water and gas metering, built for the hardest positions: specialist kit keeps reporting from deep pits and chambers, even when they flood in winter, and every read reaches one dashboard.
We supply the complete metering system: tags fitted to each meter, a ZARC Gateway on site, and the dashboard where every read arrives, with exports for the systems you already use.
Automatic meter reading
Wireless M-Bus (868 MHz T/C, 169 MHz N-mode), LoRaWAN on EU868 with ADR and auto-rejoin, NB-IoT or proprietary sub-GHz — matched to the meter's position and your network, delivered direct to your platform as reliable metering telemetry.
Pit, chamber and basement installs are the normal case here, not the exception: sub-GHz penetration, external-antenna options and IP68 sealing keep readings coming from flooded and shielded positions that defeat Wi-Fi and cellular-only devices.
A clip-on module instruments existing mechanical water and gas meters in place, across multiple manufacturers — common core, meter-specific housings — commissioned, synchronised and diagnosed locally over NFC/BLE.
Retry and resend, repeated uplinks across spreading factors, redundant payloads and on-device store-and-forward hold the data-success rate high and recover readings after an outage. Battery is modelled to a multi-year service life, with AES-128, per-device keys, encrypted storage and verified over-the-air updates.
Automated meter reading is an engineered path from the meter interface to your dashboard, built to deliver reads from basements, chambers and risers where manual reads and standard connectivity struggle.
The hard part of AMR is never the dashboard — it is the read. Water and gas meters sit in basements, flooded pits, locked risers, plant rooms, metal kiosks and underground chambers where RF is attenuated by tens of decibels. A module that performs on a bench is worthless if it cannot push a packet out of a concrete vault several times a day, for years, on one battery.
Our own tags transmit at 433 MHz, the band that reaches meters below ground and behind concrete. Where a customer already runs a metering network, we integrate with it rather than replace it: Wireless M-Bus (EN 13757-4), the European metering norm, at 868 MHz in T or C mode for accessible meters and 169 MHz N-mode, ultra-narrowband and high-power, where deep basements and buried chambers demand penetration over throughput; LoRaWAN on EU868 with adaptive data rate and auto-rejoin; or NB-IoT where cellular suits the estate.
On the meter side we work with pulse, encoder and register interfaces confirmed at survey, so existing mechanical water and gas meters are instrumented in place rather than ripped out. Alongside each read the module raises the events that matter — leak, backflow, reverse-flow and tamper — and the network runs as a star to a collector, with repeaters added where a single hop will not clear the building.
Reads land at a gateway running our own containerised stack, where they are buffered, normalised and handed to your platform or ours across a defined API. Cadence is a design decision, not a default: hourly capture aligned to the clock, or tighter, balanced against battery budget, with runtime modelled from real measured performance against duty cycle, payload, signal margin and temperature. Devices are British-made to order, with a supply chain aligned to UK security considerations.
Our specialism is making the read arrive from positions that punish radio. Retry and resend logic, repeated uplinks across spreading factors and redundant payloads are engineered to hold a high data-success rate, and every reading is written to on-device storage — months of hourly history buffered locally and retrievable on demand — so a momentary radio outage is recovered, not lost. External-antenna options and IP68 sealing keep that delivery rate intact in flooded chambers and shielded pits.
AMR here is a data-delivery and visibility layer. It supports consumption analysis, leak and continuous-flow indicators and tamper assurance; it does not replace billing-grade metrological certification or statutory metering duties, which remain with the meter and the responsible party.
Retrofit metering
Retrofit pulse, optical, register or suitable meter-interface options can be designed around existing UK water meters, including hard-to-access cupboards, basements, risers, kiosks and legacy estates.
433 MHz and 868 MHz
433 MHz, 868 MHz, LoRa-style profiles and other suitable RF approaches can be assessed against range, building fabric, gateway placement, antenna options, payload size and reporting cadence.
Buffered hourly reads
Devices can wake to capture hourly reads, retain the hourly meter history, then transmit bundled readings three or four times daily to preserve battery life and reduce unnecessary RF traffic.
Docker gateway stack
Dedicated Docker images can be supplied for gateway-aligned ingestion, normalisation, buffering and handoff, supporting client-side deployment models and integration into existing data workflows.
Battery-life engineering
Battery life is modelled for each deployment against cadence, signal margin and payload: up to five years as standard, and longer where additional cells are fitted.
Data assurance
AMR needs visibility of read capture, uplink, gateway delivery, platform acceptance, signal margin and device health, with a meter that goes quiet raising its own alert, so teams can trust the data pathway.
Deployment approach
The strongest AMR deployments prove the full route from meter to device, device to gateway, gateway to platform and platform to client workflow.
We map meter types and access constraints, confirm retrofit interface options, survey RF and gateway geometry, configure read cadence and buffering, deploy the Docker or gateway stack where required, prove data delivery in a pilot, then scale using measured acceptance criteria.
Define meter types, water or gas mix, pulse or register options, read cadence, Docker or gateway requirements and data handoff needs.
Define estate
Check basements, cupboards, kiosks, risers, cabinets, antenna placement, 433 MHz or 868 MHz coverage, gateway position and access constraints.
Confirm path
Set hourly capture, bundled transmission windows, retry logic, battery profile, gateway ingestion, data normalisation and exception rules.
Tune reads
Run representative meters through pilot acceptance, including hard locations, delivery from those positions, battery profile and data-chain verification.
Data proof
Roll the proven configuration across additional meters, sites and integrator workflows with consistent commissioning and support.
Estate rollout
Bring the meter list, site types, required read cadence, gateway requirements, battery-life targets and integration constraints. We will shape a pilot around the sites that prove the system.

FAQ
AMR collects meter readings automatically over low-power radio instead of manual visits, delivering regular time-stamped reads from water, gas and electricity meters — including meters in basements, chambers and shielded risers.
Sub-GHz radio, including Wireless M-Bus operation at 868 MHz and 433 MHz, penetrates pits, concrete and metal cabinets far better than cellular or Wi-Fi, and buffered store-and-forward delivery means reads arrive even from the hardest positions.
No. Retrofit pulse interfaces and clip-on readers work with the meters already installed, so an AMR rollout does not depend on a meter exchange programme.
Hourly interval reads are typical, buffered on the device so nothing is lost between collection windows, with delivery frequency configured around your billing-support, leakage and consumption workflows.
Devices are engineered for multi-year battery life, with the achievable figure shaped by read frequency, radio conditions and configuration — battery budget is designed per deployment, not assumed.
The system is a data-delivery and visibility layer: it delivers dependable, time-stamped reads from the installed meter. Metrological certification for statutory billing remains a property of the meter itself.
Share the meter estate, meter types, read cadence, gateways, integrator requirements and difficult locations. We will help scope a practical AMR pilot with clear acceptance criteria for read delivery, battery life and reporting.
