We want to make sure you are aware that we have very little documentation for this Modbus meter, and that Modbus will not be supported as well as the rest of our Omnimeter Models that use our EKM Protocol.  The easiest and most straightforward, from our perspective, would be to stick with a EKM protocol model and either read the meter directly over RS485, or easier yet, connect the meter to our EKM Push data system.  In other words, this model should only be purchased by those that need the Modbus protocol.

If you still are wanting modbus, please take a look at the following the Modbus software and Modbus command set:


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, 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 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 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.
