Model: EKM-Omnimeter Pulse UL v.4

EKM-OmniMeter Pulse UL v.4 -- 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 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 Omnimeter Pulse UL v.4 can count the pulses from up to 3 different pulse output devices. These could be pulses from our Pulse Output Water and Gas Meters or from any other un-powered dry contact pulse output device. Pulse Input ratios can be set in software from 1 to 9999 pulses per increment (the default ratio is now 1:1). The real-time state of the 3 Inputs can also be polled in EKM Dash software, the Omnimeter Pulse UL v.4 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 Omnimeter Pulse UL v.4 comes with 2 controllable relay outputs. These can be controlled via RS-485, either locally or over the internet from anywhere in the world using the EKM Dash. You can set the outputs to be high or low to drive an external relay. The Relay Control Outputs both provide up to 50 mA at 12 volts DC. 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).

The Omnimeter Pulse UL is also 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)

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. This meter is listed by the California Solar Initiative as eligible for Performance Based Incentives (PBI). In other words, you may be eligible to earn money back from your Utility, in California, by using one these meters to monitor the performance of your solar array. Check with your local Utility to see if you are eligible. Also, because it is certified to ANSI standards, it is possible to receive SRECs (Solar Renewable Energy Certificates) with this meter.

This meter features RS-485 communications for remote reading. It is also supported by our revolutionary cloud-based communication system that we call EKM Push. EKM Push users can also take advantage of Encompass, which is our free online dashboard and meter management suite.

This meter is also fully supported by our remote reading, EKM Dash software.

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

Hi there, I noticed that the UL listed meters come with a 10yr warranty. They do not seem to be compatible with European voltages however - eg 240Vac phase to neutral, or 415Vac phase to phase. Is there a meter that I can purchase with a 10 yr warranty that is also compatible with the higher voltages???

I'm looking for a device that can recorded KwH for different time periods, such as on and off peak times. Can this unit do this?

I've got a EKM Omnimeter Pulse UL v.4 connected to a stainless steel pulse output water meter and an external 110v relay. I'd like to turn on a relay (controls a pump) after a specified number of pulses for say 10 seconds. I can figure out how to count pulses, and I can figure out how to turn on/off a relay from DASH for s specified period of time, but I can not see how to have the pulse count trigger the relay.
