The EKM-OmniMeter Pulse v.4 is our most advanced universal smart meter to date, with the ability to count pulses from up to 3 pulse-output devices, and control 2 external relays.
This submeter is truly a worldwide - universal meter and can be used to meter any electrical system that is commonly in use in the world (as well as collect data from water and gas meters). Meters systems from 120V, single-phase, 2-wire, to 480V, 3-phase, 4-wire, both 60Hz and 50Hz. There is not an electrical system in common use that this meter will not support, other than 3 phase 3 wire (no neutral) over 415 volts specifically. Accurate to 0.5% (Class 0.5).
Here it is on our website: Omnimeter Pulse v.4
We have received accuracy certification from the California Department of Weights and Measures for revenue grade metering, also known as California Type Approval. This is an accuracy standard that many other states look to for their revenue grade requirements. Here is the certificate: EKM California Type Approval
The Omnimeters are powered by the system they are metering. kWh data will be retained in the meter, even if it loses power for up to 10 years.
This meter uses external CTs (Current Transformers) and will not function properly without them. The CTs measure the electrical current in the wires being measured. Which CTs are right for your will be determined by your type of electrical system, the maximum Amperage of your system, and the diameter of the wires being read. Solid-core CTs are less expensive but are a bit more difficult to install, they require that you disconnect or cut the wires being read and slip the CT over the wire. Split-Core CTs are more expensive but they simply clamp around the wires being read, making them much easier to install.
- Use 1 CT for single phase 2-wire systems (one hot and one neutral, with or without ground).
- Use 2 CTs for a 120/240V three-wire system (two hots and a neutral, with or without ground).
- Use 2 CTs for 3-phase 3-wire systems. (without neutral, up to 415V)
- Use 3 CTs for 3-phase 4-wire systems. (with neutral, up to 480V)
We have CTs that can meter up to 5000 amps in stock. The CT ratio is selectable inside the meter. Here is our selection of CTs: Current Transformers
These meters come with the option to remote read them and control the 2 relays with a computer.
You can read the EKM OmniMeter Pulse v.4 on the face, or set it up to be read with your computer. The remote read is a simple RS-485, 2 wire system which allows the meter string to be read from up to 4000 feet away. This string of meters can then be connected to one of our communication devices. If you need to go short range wireless, you can wirelessly bridge the hardwired RS-485 network at any point using our 485Bee wireless mesh.
We highly recommend our cloud-based meter communication system, the EKM Push — if you have internet access. The EKM Push works in conjunction with our Omnimeters by handling all of the meter communication, parsing the meter data, and inserting the reads into our cloud database. This completely eliminates all of the configuration issues of firewalls, dynamic IP, and having a computer running all the time to make the communications happen. Data is available seamlessly and immediately from your EKM Push account. The entire system has been designed to be a robust, scalable, metering system, with an easy plug-and-play installation with FREE access to your meter data.
Here is our Widget displaying live EKM Push Data: http://widget.ekmmetering.com/EKM2/?reads=100&key=MTAxMDoyMDIw&meter=10068
The Widget is quick and easy but our main software product for EKM Push users is Encompass.io.
You can also just wire the meter directly to your computer on site using our USB converter.
We also have our EKM Dash software (PC, Mac, Linux) on our website for you to try (30 day free trial). Our software will let you log the meter use. This software does not have any monthly fees and can be used on an unlimited number of meters. You can set it up to make a monthly report on any day of the month. The software can automatically generate a report and email it to you, or your tenant/user. You can also set it up so that the Dash will monitor your water use and send you an email if the usage is too high.
We have also assembled a number of customizable Metering Packages to help our customers determine which combination of products are right for their needs. Check out our all of our Packages here: Metering Packages
