Model: EKM-Omnimeter I v.3

This meter is truly a worldwide universal meter and can be used to meter a wide variety of electrical systems. It meters systems from 120V single-phase 2-wire, to 480V 3-phase 4-wire, both 60Hz and 50Hz. Accurate to 0.5% (Class 0.5). We now stock CTs for up to 5000A per phase.

The only metering system that is commonly used that this meter will NOT support is 3-phase 3-wire 480 volts (we recommend you use our EKM Omnimeter HV v.5 for this system).

This meter has been accuracy tested and certified for by the State of California Department of Weights and Measures. It is California Type Approved and meets California standards for revenue grade metering. Many other states accept California Type Approval for their metering requirements.

Note: this meter requires Current Transformers. The CT ratio can be set internally in the meter to work with up to 5000 amp CTs (no multiplier needed).

  • Use 1 CT for 120 volt single phase North American, or 230 volt 2-wire foreign systems
  • Use 2 CTs for 120/240 volt single phase systems
  • Use 2 CTs for 3-phase 3-wire systems (no neutral) up to 415 volts
  • Use 3 CTs for 3-phase 4-wire systems up to 277/480 volts

Easy clip-on DIN rail mounting.

How to install an Omnimeter (it is a v.4 Omnimeter in this case but v.3 Omnimeters are installed in a similar way):

These meters are also supported by our revolutionary EKM Push3 system. This is our cloud-based, plug-and-play, meter data solution. We are really excited about this new system, and recommend it for most remote reading applications that use our Omnimeter models. Push3 users can also take advantage of Encompass.io, which is our free online dashboard and meter management suite.


Encompass.io is our free online meter management platform for monitoring data, managing meters, generating bills, and more. It is designed specifically for people who are remotely reading their meters via the Push3 system. This platform can be used to visualize data on customizable dashboards, visualize cost, monitor trends, group meters, and a lot more. Each meter and meter group in Encompass can also be set up to email you, and/or your tenant, PDF bills. Here is a sample PDF electric bill:

EKM Widget

The EKM Widget offers another option for quickly seeing your meter data online for EKM Push users. It is also easy to save and share your Widget setting once you have it setup how you want. Here is an example:

EKM Dash

Our Omnimeters are also fully supported by our free, remote reading, EKM Dash software. If you want to read your Omnimeter on a computer locally, without the Push3 system, then this software is what you would use. You will also need an EKM Blink USB Converter in order to do so.

Customer Reviews

great meter, great price and size, did have a problem finding info on instructions

I could not figure out if I needed to set the ct values and how to do that. Could not find it in the instructions. I was able to confirm with my clamp meter that the ct values were correct (200), not sure if that was set before they sent it, or thats the default or they autosense what they are..
the lugs for the ac wires is a bit small but I should have brought smaller wires, it does say in the instructions.
otherwise is great and I like the DIN mount option.

My opinion as a contractor

My customer wanted a easy solution for monitoring his tenants usage. This equipment allows him to monitor and bill his customer with ease. We tied it into his router for wifi usage. Great price , very easy install.

Best customer service!

I've been using their equipment for about a year and it's been fantastic!! However, more importantly, we had some issues with our electrician when they were installing the meter and EKM metering was SOOO helpful. They got back to us very quickly and also had recommendations that were easy to follow. (My electrician was doing something wrong and had nothing to do with EKM metering). EKM doesn't just sell you a product and then leave you to figure it out. They are there for your every step of the way. They spend time talking to the electrician on the phone to make sure everything was installed correctly and were sooo helpful and communicative. I could not be happier with this purchase. Huge thank you to Josh on their support staff!

Great products, great service!!

We bought 66 omnimeters and 2 push products for our RV park in Canada. They worked perfectly right away and have helped us save thousands per month. Their communication is quick and efficient and they shipped our order right away. Even their after sales service is great!
I would highly recomend their products and service to anyone looking for submetering solutions.
