Energy monitoring

Factory energy monitoring from the meters you already have

Read kWh, kW, voltage, current and power factor from your existing energy meters and drives, see energy cost per machine and per unit produced, and get an alert when consumption leaves its normal range

The problem

The electricity bill arrives as one number for the whole plant

Most factories already have multifunction energy meters on their panels and drives that know their own load. Nobody reads them together, so the monthly bill cannot be traced back to a line, a shift or a machine.

One bill, no idea which machine drove it

Compressors and motors left running through breaks and idle shifts

Demand peaks that set the charge for the whole month

Meter readings written down by hand, if at all

What you get

Consumption and cost per machine, live

Sentrel reads your energy meters and drives over Modbus RTU, Modbus TCP, OPC-UA, MQTT or Siemens S7, and turns the readings into consumption, demand and cost you can act on.

Every meter on one screen

kWh, kW, voltage, current and power factor from multifunction meters, VFDs and PLCs, by machine, line and site.

Energy cost from your own tariff

Enter your energy tariff per kWh and demand charge per kW in rupees or another currency, and see energy cost, downtime cost and cost per unit produced.

Alerts on abnormal use

Set the normal range for each machine in plain English. A load that runs high, or runs when it should be idle, raises an alert in the app and by email.

What changes

Energy becomes something you manage, not something you pay

Waste shows up the day it happens, against the machine that caused it, instead of in next month's bill.

  • Idle running and leaks found and switched off
  • Peak demand visible before it sets the charge
  • Energy cost per unit for pricing and costing
  • A record of every reading for energy audits
Questions

Energy monitoring system for factories, answered.

Usually not. Many multifunction energy meters on Indian panels have a Modbus RTU port, and VFDs and PLCs already know their own load. Sentrel reads them through small gateway software on a computer already on site, an industrial PC or a Raspberry Pi. New meters are only needed where a machine has none.

Whatever your meters and drives expose: energy in kWh, power in kW, voltage, current, power factor and frequency, plus run state and runtime. Readings are checked against their limits as they arrive and kept as history for trends and audits.

Yes. Cost estimation uses your energy tariff per kWh and your demand charge per kW to show energy cost for any period, alongside downtime cost, cost per unit produced and OEE. It is included on the higher plans.

It shows where the energy goes. Typical findings are compressors and blowers running through idle hours, motors left on between shifts and loads that stack up into a demand peak. Each one can be given a limit, so it raises an alert the next time it happens.
