The three-phase electricity meter is FNN-compliant and can be used as modern measuring equipment (mME) and in an intelligent measuring system (iMSys).

  • Available with a two-rate register and grid-functionality
  • Simple and fast integration of a smart meter gateway on the DIN rail of the meter
  • Measuring accuracy in both energy flow directions (MID Class A, B)
  • Interoperability is ensured
  • Requirements of smart meter gateways, control boxes and communication technology have been taken into account during product development

Scenario

Versatile and flexible.

 

Data collection in the smart grid. The three-phase electricity meter was developed specifically for the requirements in households and small businesses. The devolo three-phase electricity meter is

optionally equipped with grid function. A total of 12 different parameters are recorded, including voltage and current values, phase angles and values derived from them. These parameters are used for determining the grid state. The three-phase electricity meter can be used as modern measuring equipment. The integrated two tariff terminals let the energy provider offer customers a two tariffs ("peak", "off-peak”), without needing the installation of an intelligent measuring system. In addition, the three-phase electricity meter can be used as a component of the intelligent measuring system. The integrated DIN rail provides space for a smart meter gateway and a control box or the communications technology. Both options for using the devolo electricity meter - as modern measuring equipment or in an intelligent measuring system - reduce the complexity involved with procuring and installing the devices. This offers the measuring point operator the greatest possible flexibility.
