Energy & Meter Monitoring — read every meter without walking to it.

Water, gas and electricity meters brought online three ways: wired M-Bus and S0 units for powered plant rooms, battery LoRaWAN readers for meters spread across a site, and cellular NB-IoT devices that need no gateway at all. Consumption data lands on a dashboard instead of a clipboard — configured in Galway before dispatch.

The Essentials

What Is Energy & Meter Monitoring?

Energy and meter monitoring — the trade calls it automatic meter reading (AMR) or sub-metering — uses connected devices to read water, gas and electricity meters remotely and continuously, instead of someone reading them monthly with a clipboard. Most meters already produce a pulse, M-Bus or Modbus output; a reader attaches to that output and transmits every reading to a dashboard, so consumption, waste, leaks and billing splits become visible day by day. TITAN IoT supplies wired, LoRaWAN and cellular meter readers in Ireland, configured before they ship.

Three Routes

Wired, LoRaWAN or Cellular — Which Suits Your Meters?

Two questions decide it: where are the meters, and is there power beside them? Plenty of Irish estates end up using a mix of all three.

Wired — M-Bus & S0

HW Group Perseus Energy units read M-Bus meters and S0 pulse outputs over LAN or LTE, feeding the SensDesk platform — graphs, alerts, scheduled PDF reports and an API. Mains powered, nothing to ever recharge.

Choose when: meters are concentrated in a plant room or riser with power and a network nearby. Skip when: meters are scattered across a site — running cable costs more than the monitoring.

Wireless — LoRaWAN Battery

Battery readers clip onto pulse outputs or circuits and transmit through walls to one gateway per site — no wiring, batteries lasting years. The Milesight EM300-DI turns any pulse-output meter into a smart meter; the CT101 clips onto a circuit for electricity.

Choose when: many meters across a campus, estate or building — one gateway covers hundreds. Skip when: you have one meter in one remote spot — a gateway for a single point rarely pays.

Cellular — NB-IoT, No Gateway

Battery readers with a SIM inside transmit straight over the mobile network — no gateway, no site infrastructure at all. Fit the Adeunis PULSE to a meter and it reports for years, anywhere there’s coverage.

Choose when: single or scattered meters — pump houses, remote sites, one meter per premises — and the fastest possible deployment. Skip when: you have dozens on one campus; per-point LoRaWAN works out leaner at scale.

Irish Applications

What Irish Sites Meter

Tenant & Sub-Metering

Landlords and facilities teams split one utility bill fairly across tenants and departments — every sub-meter read daily, billing arguments replaced by data.

EM300-DI · Perseus Energy 242

Public & Local Authority Buildings

Carbon and energy reporting obligations need a measured baseline — metered water and energy per building, gathered automatically across an estate.

CT101 · EM300-DI · Perseus Energy

Water Schemes & Leak Hunting

Continuous flow data shows night-time usage that shouldn’t be there — leaks found by pattern, not by the bill two months later. Consumption alarms come built in.

EM300-DI · Adeunis PULSE

Manufacturing Energy Audits

Clip-on CTs per line or machine show where the kilowatt-hours actually go — the measured evidence energy audits and ISO 50001 programmes are built on.

Gas Metering & ATEX Areas

Gas meters often sit in classified zones — ATEX-certified pulse readers from our range read them safely where standard devices can’t legally be installed.

Multi-Site Estates

Retail chains, franchises and utilities with one meter per premises — NB-IoT readers report from every site with no gateway and no installer callbacks.

Migration Path

Replacing 3G or Sigfox Devices? There’s a Drop-In Route.

Irish 3G networks are being switched off, and the Sigfox network’s future has pushed many metering fleets to look for a successor. The meters themselves are fine — it’s only the transmitter on top that needs to change.

The same pulse output your old devices read feeds today’s LoRaWAN and NB-IoT readers, so migration is a device swap, not a meter replacement — and we’ve already carried out exactly this changeover for Irish customers. Tell us what’s deployed and we’ll map the like-for-like replacement.

Plan Your Migration

The Swap, In Three Steps

1. Audit — what’s deployed, what outputs the meters have

2. Match — like-for-like LoRaWAN or NB-IoT reader per point

3. Swap — pre-configured devices, fitted in minutes each, data flowing to the same place

Complete the System

Readings Need a Network and a Home

LoRaWAN readers report through a LoRaWAN gateway — one per site covers hundreds of meters, pre-paired before dispatch. Cellular readers just need a TITAN IoT SIM, supplied and managed by us. Wired Perseus units connect to your LAN or their own LTE.

The readings land where you want them: HW Group’s SensDesk portal with graphs, alerts and scheduled reports; the IoT Factory platform built for smart metering; or your own system by API. Full solution, device only, or just the data — no lock-in on any path.

FAQ

Energy & Meter Monitoring Questions, Answered

What is automatic meter reading (AMR)?

Automatic meter reading uses a connected device attached to a water, gas or electricity meter to read it remotely and continuously, replacing manual monthly readings. The meter stays in place — a reader connects to its pulse, M-Bus or Modbus output and transmits every reading to a dashboard, making consumption, leaks and billing splits visible day by day.

Can I read the meters I already have?

Almost certainly. Most utility meters installed in the last twenty years produce a pulse output — a reed switch, S0 or open-collector signal — or speak M-Bus or Modbus. A retrofit reader attaches to that output and the meter becomes smart without being replaced. If you’re unsure what output a meter has, send us its model number and we’ll confirm the right reader.

Wired, LoRaWAN or NB-IoT — which reader do I need?

It comes down to where the meters are. Concentrated in a powered plant room or riser: a wired M-Bus/S0 unit is simplest and never needs a battery. Spread across one campus or building: battery LoRaWAN readers reporting to a single gateway. Scattered across many sites with one or two meters each: cellular NB-IoT readers that need no gateway at all. Mixed estates routinely use all three feeding one platform.

Do wireless meter readers need a gateway?

LoRaWAN readers do — one gateway per site typically covers hundreds of meters through walls and floors, and we pre-pair everything before dispatch. NB-IoT readers don’t: they have cellular built in and transmit directly over the mobile network with a TITAN IoT SIM, which is why they suit single or scattered meters where installing a gateway wouldn’t pay.

Can I replace my old 3G or Sigfox meter readers?

Yes, and usually without touching the meters. Legacy readers connect to the same pulse output that modern LoRaWAN and NB-IoT devices use, so migration is a like-for-like device swap — each point takes minutes, and the data carries on flowing to your platform. With Irish 3G switch-offs underway and the Sigfox network’s future uncertain, we’ve already run this changeover for Irish customers.

Can gas meters in ATEX zones be monitored?

Yes — but only with equipment certified for the zone. Gas meters commonly sit in ATEX-classified areas where standard electronics can’t legally be installed, and our range includes ATEX-certified pulse readers built exactly for this. Tell us the zone classification and meter type and we’ll specify a compliant reader.
