Water Meter Digitization

Your analog meters,
reading themselves.

Retrofit any mechanical water meter in under 60 seconds — no pipework, no meter swap. The W-Sensor uses edge AI + optical reading to deliver hourly data, automatic leak alerts and remote monitoring from day one.

From sensor to insight

Simple steps.
Powerful impact.

No civil works. No water shut-off. No specialist contractor. A technician clips the W-Sensor onto the meter face and walks away — the rest is automatic.

  1. 1

    Install W-Sensors

    Mount directly onto meters, pipes, or distribution points. Universal adapter. No tools, no pipework, no water shut-off needed.

    Under 60 seconds
  2. 2

    Collect data continuously

    The edge-AI camera reads your meter face and teaches itself. Hourly readings. 99%+ accuracy after a short self-calibration window.

    Every hour, 24/7
  3. 3

    Analyze via Edge & Cloud AI

    Anomaly detection, usage forecasting and consumption prediction — processed at the sensor edge and enriched in Mimir for full-network visibility.

    Real-time alerts
  4. 4

    Act with confidence

    Alerts, maintenance planning, billing-ready exports. Data flows to your SCADA, billing or asset management system via open API.

Why Waltero

Engineered for accuracy.
Built for resilience.

Not all sensors are created equal. The W-Sensor sets the standard for infrastructure-grade optical meter reading — in environments where reliability is non-negotiable.

Reads any meter — optical & dial

The AI camera recognizes numeric displays, rotating dials and signal indicators across hundreds of meter models. No manufacturer lock-in. If the meter has a visible face, the W-Sensor reads it.

Any make. Any age.

Connectivity built in: NB-IoT, LTE-M & Wi-Fi

Operates on NB-IoT, LTE-M or Wi-Fi — whichever fits your infrastructure. No gateway to deploy for cellular deployments, no local network required. Works in meter pits, vaults and basements with marginal signal.

Zero infra overhead.

IP68 · 10-year battery · field-replaceable

Fully sealed against water ingress. Batteries last a decade under normal operation. A technician swaps them in minutes — no reconfiguration, no downtime.

Deploy and forget.

Hourly leak detection & night-flow analysis

Automated minimum night-flow monitoring runs continuously. Mimir flags anomalies the moment they appear — leak detection is vastly improved compared to manual methods, catching issues before they become costly.

Stop NRW early.

Instant data — no setup, no configuration

The W-Sensor's OCR engine starts producing accurate readings immediately after installation — no training period, no meter-specific configuration required. Mount it, connect it, and data flows straight away.

Truly plug & play.

Open API — no vendor lock-in

Mimir integrates with existing SCADA, billing and asset management systems via REST API and MQTT. No walled garden — your data flows directly into the tools and workflows your team already relies on.

Your stack. Your data.

Typical project

From kick-off to full network visibility in 8 weeks

Waltero's structured deployment methodology de-risks every project before large-scale rollout begins. The Exploratory Kit is a smart step one.

Phase 1

Exploratory Kit — pilot

5–20 W-Sensors deployed on a representative sample. Accuracy, connectivity and alert thresholds validated in your specific environment. Full Mimir access from day one.

Weeks 1–2

Phase 3

Full network rollout

Sensors deploy across the full meter estate via Waltero's partner network. Each meter auto-registers to Mimir — no manual configuration per unit required.

Weeks 5–7

Phase 2

Business case & integration design

Pilot data supports a quantified ROI model. Mimir API integrations mapped to SCADA or billing systems. Alert thresholds, reporting cadence and team access defined.

Weeks 3–4

Phase 4

Go-live & hypercare

Operations team onboarding, dashboard configuration and 90-day hypercare support.

Week 8 onwards

Technical specification

Engineering-grade hardware for infrastructure environments

The W-Sensor is designed from the ground up for unattended operation in the demanding conditions of water utility infrastructure.

The numbers

The problem is large.
The gap is still wide open.

Industry data on the scale of water loss and the digitization gap that still exists — even in the most advanced utility markets.
