PLEASE NOTE - This is a new (December 2018) beta release product. We are soft launching this new product as a beta release while we continue to validate the hardware and firmware (we are currently tracking no issues). If you are interested in helping us beta test this new meter, we recommend that you order no more that one or two for now. We would appreciate any feedback that you have regarding the performance of the meter.
EKM-Omnimeter HV v.5 –– Our most advanced universal smart kWh meter to date, capable of metering any electrical system in common use around the world, with the ability to count pulses from up to 3 pulse-output devices, and control 2 external relays. This is truly the one meter to meet all of your metering needs!
The Omnimeter HV v.5 is a revenue-grade universal kWh meter that can meter a very wide range of electrical systems. These include single-phase 2-wire 110–600 VAC, single phase 3-wire 110–600 VAC, 3-phase 3-wire 110–600 VAC, or 3-phase 4-wire 110–600 VAC. This is the only Omnimeter model that is capable of metering 3-phase 3-wire systems above 415 VAC, and any electrical system above 480 VAC.It will operate on systems of 50 or 60 Hz. It supports Current Transformers (CTs) from 100A to 5000A. This meter will work with any electrical system in commonly use around the world. Accurate to 0.5% (Class 0.5)
This meter uses our full range of external Current Transformers (you cannot meter power/energy without at least one of these). The CT ratio can be set internally in the meter in order for it 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
In addition to, or instead of, metering electricity, the Omnimeter HV v.5 can also count the pulses from up to 3 different pulse output devices, such as our Water Meters and Gas Meters or from any other un-powered dry contact pulse output device. as is explained in this video. Pulse Input ratios can be set in software from 1 to 9999 pulses per increment (the default ratio is 1:1). The real-time state of the 3 Inputs can also be polled in EKM Dash software, the Omnimeter HV v.5 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 HV v.5 also 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 theEKM Dash. 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. Two LED lights on the face of the meter indicate the on/off state of each output. Control theEKM-Switch120directly, 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). Please note that the relays cannot be controlled when reading the meter with the current version of the EKM Push system (Push2). You will need to be reading the meter with an EKM Blink USB Converter, iSerial, or wait for the next version of the EKM Push system (Push3).
This meter has a tray for an optional 18650 Lithium Ion battery cell (3.2–4.2VDC). The battery will ensure that the meter remains powered in the event that AC voltage is down for a period of at least 30 minutes with a full battery. This enables the meter to continue to communicate via RS-485 (with an EKM Push gateway for example), continue to count pulses from water and/or gas meters, and continue to actuate its control relays. The meter will charge and maintain the 18650 cell at ~4.2VDC so it is ready for any AC outage. Optional battery not included.
Three LED lights at the right of meter's LCD screen indicate if there is voltage, if there is current, and the direction of current on each of up to 3 lines. Refer to the last page of this meter's spec sheet (linked below) to learn how to correctly interpret these LEDs and their blinking patterns.
The Omnimeter HV v.5 is also great option for solar Net Metering. In addition to Total and Reverse kWh, that all of our Omnimeter models provide, this meter also provides 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 power to, or pulling power from, the grid.
How to install an Omnimeter (similar for all Omnimeter models):
These meters are also supported by our revolutionary EKM Push 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. EKM Push 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 and managing meters. It is designed specifically for people who are remotely reading their meters via the EKM Push system. This platform can be used to visualize usage on dashboards, visualize cost, monitor trends, group meters, and a lot more. Each meter in Encompass can also be set up to email you PDF and CSV reports that you can use to monitor you meters and/or use for billing. Here is a sample PDF report:
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 Push system, then this software is what you would use. You will also need an EKM Blink USB Converter in order to do so.
