Power Meter Technics · Utility metering since 1994
Accurate measurement,
trustworthy meter data.
Power Meter Technics is a South African metering engineering company with more than three decades of experience in electricity measurement. We develop our own metering software, supply and support metering systems, acquire and manage meter data at scale, and operate a SANAS-accredited calibration laboratory. From the meter in the field to the data used for billing, analysis and reporting, our focus has always been the same: accurate measurement and trustworthy data.

One company, the whole chain
Most companies in metering do one part of the job. Software vendors manage the data. Meter manufacturers build the hardware. Reading bureaux collect the readings. Calibration laboratories establish whether the measurements are right. PMT does all four. We design and supply meters, develop the software that reads and manages them, operate the systems that turn millions of readings into usable information, and run our own SANAS-accredited calibration laboratory. It means we understand the entire measurement chain, from the electricity passing through the meter to the data ultimately used for billing, analysis and reporting.
Our flagship, MOL, has been developed in-house since 1998, now handling half-hourly data from more than 109,000 meters. The rest of the business exists to make sure the numbers reaching it are right.
The platform
01 / 04MOL
Cloud meter data management covering acquisition from any major meter, validation, tariffs and billing, prepayment, analytics and revenue management. Developed in-house since 1998.

The hardware
02 / 04Meters & communications
Single and three-phase smart meters, CT and DIN-rail meters, and the gateways that connect them, designed to PMT's specification for the system they feed.

The people
03 / 04Metering services
Meter reading, bill verification, tariff analysis, installation and project management, provided as an outsourced service or alongside your own team.

04 / 04Calibration laboratory
SANAS-accredited to ISO/IEC 17025 since 1997, on site as well as in the laboratory. Forensic calibration for utilities investigating tampering is separate work, and depends on that accreditation.

Metering companies don't write billing platforms. Software companies don't understand metrology.
MOL was built by metering engineers, not by a software house adding metering as an afterthought. The distinction shows up where it matters: in how a phasor diagram catches a reversed CT before it becomes a billing dispute, in how a summated account diversifies demand correctly, and in what happens when a billing cycle straddles a tariff change. These are not software problems that happen to involve electricity. They are metering problems, and the software has to understand them.
“Everything on the bill is considered wrong until MOL proves it right.”
Solutions
Metering and MOL by sector.
Municipalities & utilities
Revenue that can be defended at audit
Large power user metering, outage detection through PMT's last-gasp gateways, and billing determinants that hold up when a customer queries them.
Property funds & centre managers
Tenant recoveries that reconcile
Tenant sub-metering, standby generation cost recovery and solar apportionment, handled in software without duplicating the reticulation.
Multi-site corporates
Energy data for every site
Interval data across every site, weather-normalised baselines, and bill verification that checks the tariff as well as the reading.
Metering hardware
Revenue-grade meters, designed and calibrated by PMT.
MOL reads any major meter, but PMT also designs its own range. Knowing exactly how an instrument behaves determines whether its data can be billed on without dispute. Every meter we supply is calibrated in our own SANAS-accredited laboratory before it leaves us.

Why the data can be trusted
We calibrate the meters ourselves, in our own accredited laboratory.
Billing is only as good as the measurements underneath it. PMT has held SANAS accreditation to ISO/IEC 17025 since 1997, for calibration on site as well as in the laboratory. Our forensic work, where a utility is investigating tampering, is separate from that accreditation but depends on it.
