Metron (Smart Reader)

Find Non-revenue Water. Eliminate Water Loss. One Meter at a Time.

In collaboration with Infineon Technologies

THE PROBLEM

Non-Revenue Water, by the numbers:

US$39B.

lost to non-revenue water globally each year

~38%

average NRW rate across Southeast Asian utilities

1/3 Litres

of treated water never reaching the end user

THE CHALLENGE

Smart Meter Solutions That Don't Scale

Existing AMI systems are costly to deploy, demand full infrastructure replacement, and remain financially out of reach for most utilities.

Invasive & Disruptive

Smart meter rollouts require full hardware replacement, civil works, and service interruptions — making district-wide migration a years-long undertaking.

Expensive & Unscalable

High per-unit hardware, installation, and maintenance costs make large-scale rollout economically unviable.

Pulse Retrofit Drift

Pulse counters and tap-on sensors lose accuracy over time, and errors compound, stacking into significant miscalculations.

How do we make every meter smart without replacing them?

Non-revenue water reduction begins with continuous, accurate data. Metron delivers it on the meters you already own.

No rip-and-replace, no civil works, no downtime.

INTRODUCING

Universal Clamp-On AI Smart Meter Reader

No replacement. No civil works. No disruption.

Deployed in minutes. Intelligent from day one.

Mount it. Walk away. See everything.

Metron is a self-provisioning IoT camera module that turns any analog utility meter into a smart meter. Attach to any existing water meter and it reads continuously with on-device AI, detecting leaks, bursts, and non-revenue water the day they start.

No plumber. No permit. No downtime.

5-10 years

Self-provisioning

AI-driven calibration. No manual setup.

24/7

Continuous monitoring

Detect leakage early. Reduce NRW.

Any

brand / type of numeric dial meters

Plug and play. No meter swap required.

A smart reader.
Not a smart meter.

TackEvo Metron does not replace your meter. It reads it. The certified mechanical meter stays in place as your instrument of record, so there is no re-certification, no metrology approval cycle, and no disruption to supply. You keep the meter you trust and make it intelligent.

Because Metron reads the dial rather than measuring flow, it works on virtually any meter you already own, mechanical or digital, from any manufacturer.

KEY FEATURES

UNIVERSAL COMPATIBILITY

Reads virtually any numeric-dial water meter, mechanical or digital, from any maker. One device fits your mixed fleet.

HYBRID AI INTELLIGENCE

On-device AI reads the meter while the cloud verifies and refines every reading. The result is accurate, auditable data you can trust for billing.

EFFORTLESS DEPLOYMENT

Attaches directly to existing meters with no cutting, no pipe work, and no service interruption. Deploy in minutes, not months.

Predictive AI & Integrated Alerts

Instant anomaly alerts via push notification, email, or SMS. Catch leaks before they become losses.

Early Leak & Burst Detection

Continuous monitoring flags abnormal flow the day it starts, not on the next service visit.

Non-Revenue Water Visibility

Continuous data across districts and DMA entry points helps localise where water is being lost.

Billing Integrity

Every read is time-stamped and cryptographically signed, creating a dispute-proof record of what the certified meter displayed.

Demand & Planning Insight

Granular consumption patterns reveal peak demand and usage trends that quarterly reads cannot show.

Most utilities are losing 20–50% of treated water before it ever reaches a customer.

The solution you choose makes all the difference. See how Metron stacks up against the alternatives.
