What is Kilowatt Hour (kWh) Metering?
Using a sub meter for kilowatt hour metering provides a critical window into your energy consumption and ultimately the energy bill. Users are able to accurately monitor the energy usage in real-time instead of waiting until the end of the billing cycle; with revenue grade meters like the Acuvim II users can verify bills for accuracy and/or allot charges to specific areas or users; using meters with onboard memory for data logging such as Acuvim IIR these records can be saved internally on the meter.Also available, the Acuvim-EL and AcuRev 1310 excel in low-cost and simple effective energy monitoring; displaying clear data and allowing for energy saving opportunities to become apparent. All of the tools available in an energy meter are in essence made to create accountability for energy usage and in turn help save money. These kWh meters can be purchased as individual items, kits including the accessories for installation, or pre-wired panels which minimize installation time, and create a dynamic plug n’ play solution.

Recommended kWh Metering Solutions
This revenue-grade meter is the ideal cost-effective solution for basic kWh metering applications. Metering data is simple to read and is made available on the LCD screen through the press of a button.
Revenue-grade kWh meter, the IIR is designed for remote and historical metering with on-board data logging and a wealth of communication options. The IIR also offers additional metering parameters which enable greater versatility.
Economical revenue-grade kWh metering in a compact DIN-rail mountable enclosure. The 1310 series offers multi-circuit metering allowing for multi-tenant or load specific monitoring.
Take Control of Your Energy Bill
Your energy bill is charged based on the total kilowatt hour consumption over a stated time period; typically in a month by month format. In large enterprises and innovative companies have taken measures to capture this figure and create accountability for the energy usage through energy audits, engineering solutions, load-shedding, demand response and through the most basic and essential form; kWh sub metering.
Metering Kilowatt Hour Consumption
kWh meters are compact electronic monitoring devices that measure the consumed energy flowing through a circuit such as a standard 120V or 240Vac line and act as a kWh calculator. The meter is mounted in line with the circuit supplying the electricity such as a main panel or distribution sub panel and will accumulate a totalized reading accounting for the consumption flowing through. The accumulated number is the total power in kilowatts that has been used over a period of time, thus giving you the energy as expressed in kilowatt hour. The accumulated number is derived from all of the devices that are feeding from that circuit’s energy and can be read as the imported energy – displayed as Ep_imp on most Acuvim meters. This number can be reset after the end of the billing period or taken down and subtracted from the rolling total to calculate the next periods total energy use.
kWh Metering Frequently Asked Questions (FAQ)
- A kWh Meter:
Preferably ANSI C12 certified revenue grade.
Talk to your representative but they should include items like current transformers.
- A Designated Circuit:
Determine where you will be monitoring the energy, typically a 120V or 240V main.
Installation will vary based on the circuit; all meters come with simple directions which can be read easily by an electrician.
After the meter is installed, results will show immediately – what you do with those results is entirely up to you.
kWh. Make sure that you are reading the ‘imported’ or consumed energy as that is what you are using and being billed for.
kWh metering projects range from home owners, landlords, and small businesses up to major companies and organizations.
