Model: EKM-Omnimeter Pulse v.4

The Omnimeter Pulse v.4 is our most advanced universal smart meter to date, with the ability to count pulses from up to 3x pulse-output devices, and control 2x external relays. 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 or single phase 120/240V 3-wire, 120V to 480 volts, or 3-phase 3-wire 120 to 415 volts or 3-phase 4-wire 120 to 480V, 50/60Hz , 50/60 Hz. It Supports CTs from 100A to 5000A.  Accurate to 0.5% (Class 0.5)

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. 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, or locally when reading the meter with a USB Converter.

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.

This meter uses our full range of compact Current Transformers (it cannot meter electricity with out at least one). 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 Push3 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 EKM Push3 system, then this software is what you would use. You will also need an EKM Blink USB Converter in order to do so.

Excellent Product

This meter is awesome. We have a solar PV array on our house, and even though it cant work with the PUSH system yet, it still indicates the direction of current. Well done. Great product.
