Model: EKM-Omnimeter Pulse UL v.4

The Omnimeter Pulse UL v.4 is our most advanced universal smart meter to date, now with the ability to count pulses from up to 3 pulse-output devices, and control 2 external relays. This model is certified to meet (it actually exceeds) ANSI C12.1 and C12.20 standards. It is also UL and cUL Listed. This is truly the one meter to meet all of your metering needs!

This is a revenue-grade universal kWh meter. It can meter systems ranging from single-phase 120V 2-wire, single-phase 120/240V 3-wire, 3-phase 3-wire 120 to 240 volts, or 3-phase 4-wire 120 to 240V. 50/60Hz. It Supports CTs from 100A to 5000A. This meter will work with any system that is commonly used in the world. Accurate to 0.5% (Class 0.5)

This meter has been designed to meet California's 2013 Title 24 (page 151) requirements for energy management and service metering (Section 130.5A). Depending on the service, these requirements can include – Instantaneous kW demand, resettable kWh, historical peak demand, and kWh per rate period; all of which are provided by this meter.

The v.4 Omnimeters can also count the pulses from up to 3 different pulse output devices, as is explained in this video. These could be pulses from our Pulse Output Water and Gas Meters or from any other un-powered dry contact pulse output device. The real-time state of the three Inputs can also be polled remotely by our EKM Push3 gateway. The Omnimeter data will return a High or Low state for each pin in real-time (use this for sensing switch states, open or closed doors, etc).

The v.4 Omnimeters also include 2x controllable relay outputs. These can be controlled via RS-485, either locally via our EKM Dash software, or remotely online via our Push3 gateway. You can set the outputs to be high or low to drive an external relay. The Relay Control Outputs can continuously provide up to 50 mA at 12 volts DC each. Control the EKM-Switch120 directly, or control lights, motors, entire buildings, implement Demand Response, Load Shedding, etc. via relay control. The Relay Control Outputs can also be set to go ON or OFF from 1 to 9999 seconds.  These outputs can also be controlled via EKM Push3 triggering. The real-time state of the outputs can also be polled via RS485. The outputs can also be used to power an external device (Wireless 485Bee Module, sensors, etc). Relays can be controlled online when reading the meter with the EKM Push3 data system either manually, via the API, or using triggersor locally when reading the meter with a USB Converter.

The Omnimeter Pulse is also great option for solar Net Metering. In addition to Total and Reverse kWh, that all of our Omnimeter models provide, these meters also provide the direction of current in real time. This makes it possible to know, in real time, if you are generating more power than you are consuming, and whether you are sending or pulling power, to or from the grid. Also, because it is certified to ANSI standards, it is possible to receive SRECs (Solar Renewable Energy Certificates) with this meter.

This meter uses our full range of compact Current Transformers (it cannot meter electricity with out at least one CT, but can be used as just a pulse counter if you do not have CTs). The CT ratio can be set internally 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)
  • Use 3 CTs for 3-phase 4-wire systems

Easy clip-on DIN Rail Mounting.

How to install an Omnimeter Pulse v.4:

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.

Really Great And Easy to setup system

Im in the rental business and we have two new duplex units with only one water meter per building. I purchased 4 Water Meters and Two Gas Meters. So Far on one duplex, I have two water meters and one gas meter along with electrical metering hooked up to one of these controller meters. Everything wires up easily right to the push computer. I have started playing around with the Billing software, it has some great features but im already thinking about building a Filemaker Database with more custom features using the API. Looking forward to using more of these in the future.

Economical and reliable system

I bought EKM's 3/4 inch water meter, EKM Push and EKM omni meter to measure water flow remotely as we supply water to 30 homes and need to know if any disruption to the supply water to tank. This is very economical and reliable device. Paid less than $800 dollar for all the three and I have a good tool now to measure the water. I connected it also to 2 inch Stenner old water meter as it can measure upto 3 meters. Water meter need to have pulse feature though. Free EKM cloud based dash software shows how much water was pumped both 2 inch meter and 3/4 inch meter. I can know minute to minute flow rates by logging into EKM free software's (3 software's are available). Cloud based system is free and no monthly charges. I strongly recommend this. Thank you for this great product.

Very useful device

I installed this meter as a part of garage electrification project. I have a separate service entrance from PSE coming directly from the transformer.

I really appreciate how EKM team came with the idea of submetering solution. I currently use it with RS485 interface connected to the Raspberry Pi, Andino Pi as a host. I noticed a small difference in total between PSE meter and EKM meter (313 vs 310).

I like the choice of CTs, easy installation steps, fully open protocol, python libs (had to did some legwork to make them python 3 compatible).
