Submetering is all about collecting energy data and being able to output that data into a usable report whether it’s to allocate costs or interpret the data for additional energy saving opportunities.

When designing a submetering system, the first step should be to determine what needs to be measured and how the data will be collected and transmitted.

Ask yourself the following questions to determine what VerifEye meter series you should use:

1. Will you be measuring electric, gas, water or steam?

• If electric, will you be metering
  • Single Phase
  • Three Phase
  • Split Phase
  • WYE
  • DELTA

2. What are your measuring parameter requirements?

• kWh consumption—use Mini Meter or Series 1000
• Local peak demand reset—use Series 2000
• Additional data parameters (Volts, Amps, Power Factor, etc.)—use Series 4000 and 4100, Series 7000 and 7100, or Series 8000

Next, answer the following questions to determine which VerifEye meter catalog number you should use:

1. Where is the meter going to be installed?

• Indoor
• Outdoor
• Electrical panel

2. What is the voltage rating? See the Electrical Configuration Matrix below.

3. What types of current transformers (CTs) will you be using?

• Solid core CTs—ideal for retrofits
• Split core CTs—ideal for new construction
• Rogowski coil CTs—easy to install

4. Will you need disaggregation of loads (multi-circuit monitoring)? Use MMUs, Series 7000 and 7100, or Series 8000
