Meatrol ME537- Three phase energy logger
€350.00 excl. VAT
The Meatrol ME537 is full colour screen, three phase power quality analyser, externally connected with open type Rogowski coil or voltage type CTs.
Install this meter and log a building’s energy usage.
This three-phase energy logger is ideal for the following:
- Determining the energy usage/load profile of a building’s energy usage over a period of time.
- Determining a building’s peak power usage.
- Testing the quality of supply for example voltage dips and harmonic analysis.
The results from the energy logging can be used to:
- Identify cost-saving opportunities from energy efficiency measures.
- Identify cost-saving opportunities from improving a building’s Power Factor and Peak-demand(KVA) requirements.
- Monitor and check for phase imbalances to prevent overloading one phase.

This three-phase energy logger is ideal for the following.
- Determining the energy usage/load profile of a building’s energy usage over a period of time.
- Determining a building’s peak power usage.
- Testing the quality of supply for example voltage dips and harmonic analysis, and establishing if voltage levels are in the acceptable range for PV Inverters.
The results from the energy logging can be used for the following.
Plan capacity and expansion
- Add machines or a new production line — confirm your supply has the headroom before you order equipment.
- Install EV charge points — work out how many your existing connection can support.
- Add heat pumps, HVAC, or other large loads — check available capacity before installation.
- Avoid an unnecessary supply upgrade — or plan one with confidence if the data shows you need it.
Cut energy costs and improve power quality
- Identify cost-saving opportunities from energy efficiency measures.
- Improve a building’s power factor, which is inflating the bill.
- Reduce peak-demand (KVA) charges — monitor what is causing high KVA usage and when.
- Balance loads across phases to prevent overloading one phase.
Size solar, storage and backup systems
- Plan solar PV systems and determine the number of panels needed.
- Plan backup power systems — determine inverter and battery capacity.
- Determine backup generator size requirements.

Frequently Asked Questions
This meter is not supplied with any Rogowski coils or CTs (Current Transformers). You need to purchase these separately in the sizes you require. Click the following links below to add them to your order.
- Current Transformers
- Rogowski Coils (Choose the 2-pin connector type)
This meter has current input connections for three-phases plus neutral, so it requires four coils or CTs in total.
The meter is not powered up by the voltage from the voltage sensing input ports. Separate power needs to be wired to the power supply ports of the meter. The meter can be power by AC power from 85V to 305V.
The sample rate can be set to one of the following values:
0= 1kHz
1= 2kHz
2= 4kHz
3= 8kHz
The minimum logging interval of the ME537 is five seconds. Because of the amount of data recorded, shorter logging intervals are not possible.
Meter data analysis, visualisation and reporting
We have created an Excel template that can analyse the data and visualise it with graphs. It has the following features and graphs.
- Maximum power per minute, hour and day
- Energy usage per minute, hour and day
- Maximum voltage per minute, hour and day
- Limit data displayed to a specific day or hour
- Supports three-phase and single-phase setups
This template and support with importing the data and using the template are included free of charge when purchasing this meter.
The template is very easy to use even for users that is not that familiar with Excel. We have also created step by step instructions document and video.
