Metering hardware
Revenue-grade meters, designed and calibrated by PMT.
MOL reads any major meter — but PMT designs its own range, because knowing exactly how an instrument behaves is the difference between data you can bill on and data you have to argue about. Every meter we supply is calibrated in our own SANAS-accredited laboratory before it leaves us.

Smart meters — at the supply point
The revenue meter where the utility's supply enters the property. Communicates over power line or RF to a data concentrator, carries time-of-use tariffs, logs events and tamper attempts, and — on direct-connected models — can disconnect and reconnect remotely. This is the meter the bill is raised against.
DIN-rail meters — inside the board
Compact, revenue-grade rail-mounted meters for points downstream of the supply point: individual tenants, floors, plant, chillers, common area. Wired over RS-485 to a gateway rather than communicating over the grid, and sized so that many fit in one distribution board.
Every meter PMT sells is revenue grade, wherever it is installed. Most installations use both: a smart meter proving what the utility supplied, and DIN-rail meters measuring what each tenant actually consumed. The two together are what make tenant recovery reconcile.
The basics
What makes a meter smart?
A conventional meter keeps one running total, and somebody has to go and read it. A smart meter records when the energy was used as well as how much — interval by interval — and sends those readings back on its own, without anyone visiting site.
That difference is what makes everything downstream possible: time-of-use billing, maximum demand, load profiles, tenant recovery and bill verification all depend on knowing what happened in each half hour, not just across the month.
01
It measures in intervals
A twelve-channel load profile records consumption and demand interval by interval — the half-hourly data MOL bills and analyses on.
02
It talks both ways
Readings travel over power line or RF to a data concentrator, and on to MOL. Instructions and tariff changes travel back the same way.
03
It knows the time
A replaceable battery-backed real-time clock lets the meter carry time-of-use tariffs itself, so every interval lands in the right tariff period.
04
It measures all four quadrants
Active and reactive energy, imported and exported — which matters the moment a site has solar or a generator.
05
It reports on itself
Events and tamper attempts are logged by the meter and surfaced in MOL: phase loss, reverse energy, and a last-gasp notification when the power goes.
06
It can switch the supply
Direct-connected models carry an integrated load switch, so a supply can be disconnected and reconnected remotely.

How smart meters report
The data concentrator
POWER LINK DCU
Smart meters on a power line network don't each need their own SIM card. The POWER LINK range communicates over HD-PLC — high-definition power line communication, which uses OFDM modulation and error correction to carry far more data, more reliably, than conventional PLC — across the existing low-voltage reticulation, with no new wiring.
The concentrator manages the mesh, collects from up to roughly a thousand meters, and carries the aggregated data back to MOL over a single cellular connection. One backhaul link instead of a thousand, in a dense installation.
In hybrid mode the meters add a mesh radio channel to HD-PLC, so every meter can reach the concentrator over the power line, over RF, or through its neighbours — extending coverage and keeping readings flowing where one path is poor. DLMS/COSEM runs end to end, from the instrument to the invoice.

Cellular modems
MOL SN4G · 4G/GPRS
Not every meter sits on a power line mesh. A single intake, a bulk supply point or an isolated site is reached directly instead: the SN4G connects to the meter's serial port and carries its readings to MOL over the cellular network.

Inside the board
DIN-rail meters
Class 1 active and Class 2 reactive, Modbus RTU over RS-485, four tariff registers and a four-channel load profile. Revenue grade, like every meter we sell — so a landlord can bill a tenant directly on them.

Every meter is calibrated before it ships.
A specification is a claim about a population. A calibration certificate is a measurement of the instrument you were actually sent. PMT calibrates in its own laboratory, accredited by SANAS to ISO/IEC 17025 since 1995, to a measurement uncertainty of ±0.03% — and you get the certificate.
