Things to consider when shopping for the right power meter

Smart power metres may be used to display real-time electricity usage, assist with load control and transformer monitoring, and provide power monitoring.Smart power metres can save you time and money by automatically reducing energy use when it is not required. Touch Screen PLCs, data loggers, Programmable Automation Controllers, and PCs with SCADA software may all be used to control, monitor, and display data in an easy-to-understand and analyse format.So, what factors should you think about while choosing the right electric power meter from a good brand. 

Three-phase or single-phase

The first thing to consider when selecting an energy metre is the number of phases require for the system. Single-phase and three-phase power metres are available from most providers currently. You’ll need a single-phase power metre if the current system you’re logging data from is single-phase. If you’re working with a three-phase electric system, you’ll only be able to utilise a three-phase power metre. Single-phase power metres like the PM-3112 and PM-3114 are small, din-rail mountable, and versatile enough to be use in a variety of energy monitoring applications.

Amount of Amps

After you’ve determined the phase of the power metre, you’ll need to figure out how many amps you’ll need for the system. The most frequent amp selections available on intelligent power metres are 60 amps, 100 amps, and 200 amps. The amount of amps supported varies depending on the power system. If you use a 60A power metre for a power measurement system that requires 100A, it will not operate. Get in touch with the right energy meter manufacturers in India for the right product in your hand.¬†

Protocols of Communication

Smart Power Meters communicate via a variety of channels and protocols, so it’s crucial to figure out which one yours uses. In industrial applications, Modbus is one of the most widely use protocols. Modbus, which was create by MODICON in 1979, has evolve into a standardise, freely available, and simple-to-use protocol for connecting industrial equipment. Modbus-compatible smart power metres are easy to connect with your existing Modbus systems. For example, the PM-3112 supports Modbus RTU, but the PM-3112-MTCP uses Modbus TCP.

What Else Is There?

What more do we need for a good energy monitoring system now that we’ve addressed phases, amps, and communication protocols? One of the most significant benefits of smart power metres is that they may be link to SCADA. And HMI software to automate the entire system. It can display the status of your equipment, send email or text message alarms, log data, apply control. And produce reports using SCADA software. Touch Screen Controllers, such as the TPD-433, may also be use in home automation projects to display real-time power usage statistics and control electronic devices using a touchpad.


Many things must be consider while selecting the proper power metre. A power metre must fulfil particular standards. Whether it is for tenant submetering, commercial building submetering, power monitoring for energy management, or another purpose. While each application will have its unique set of needs, there are a few general variables to consider.
