Smart meter


Electricity metering today works in an intelligent way. With our products, we take account of the digital energy revolution and are fully in line with the Forum Netztechnik/ Netzbetrieb and the FNN specifications. The advantages over the old mechanical meters are numerous. Examples are a higher measuring accuracy, extended protection against manipulation, a higher stability and a lower energy consumption.

A new generation is also being heralded because smart meter enable consumption information to be provided in real time, allowing energy bills to be made during the year and, in addition to pure electricity consumption and also facilitate statistical evaluations depending on machine, department, time of day, etc. As part of the digital energy revolution, companies can also be dynamically priced and thus use low-cost low-load times.

DVSB(R)

Electronic three-phase meter / smart meter Metering System-2020

Three phase - 4 wire direct connected electricity meters of the DVSB series are manufactured in accordance with FNN specifications “Basiszähler” version 1.4. According to EnWG, they are used as measuring instruments together with a BSI Smart Meter Gateway as intelligent metering system (iMSys) or individually as so called “moderne Messeinrichtung” (mME) below the installation obligation for iMSys.

The three phase - 4 wire direct connected electricity meters of DZG are currently available in the direct measuring version for SLP measurement as type DVSB or for RLM measurement as type DVSBR. The corresponding metering technology for semi-direct measurement in the low-voltage grid is currently still under development. The DVSB series is supplemented by the DWSB version, which has a 1-phase approval (L3) for use as an alternating current meter. All other performance criteria comply with DVSB.

The DVSB is optionally available with a double tariff meter that can be controlled via terminals.

DVS74

Three phase electronic electricity meter

Electricity meter for active consumption measurement in accordance with §29(3) and §61(3) of the Measuring Point Operating Act (MsbG) of 29.08.2016, as well as FNN - Specifications “Basiszähler Funktionale Merkmale” version 1.4.

This meter can be upgraded to an intelligent metering system (iMSys) according to §21(1) MsbG by means of a pluggable LMN interface.

The DWS74 differs from the DVS74 by the extension to the 1-phase approval for use as an alternating current meter. Here an optional factory configuration of up to three phases for L1, L2 and L3 each can be carried out on delivery.

Alternative data interfaces expand its function and make the meter interesting for the sales networks of municipal utilities.

PlugIn versions:

  • LMN (according to FNN)
  • LoRa (with integrated wMBus)
  • RS485
  • Bluetooth

The DVS74 is optionally available with various terminal cover versions:

  • Standard terminal cover (L 100 mm, free space 50 mm)
  • Long terminal cover (L 162 mm, free space 120 mm)
  • Middle terminal cover (L 120 mm, free space 80 mm)
  • Piggyback terminal cover for mounting accessories with three-point mounting (L 162 mm, free space 120 mm)
  • DIN rail terminal cover with module cover (e.g. for the use of a Smart Meter Gateway)

DVS76

Three phase electronic electricity meter

Electricity meter for active consumption measurement in accordance with §29(3) and §61(3) of the Measuring Point Operating Act (MsbG) of 29.08.2016, as well as FNN - Specifications “Basiszähler Funktionale Merkmale” version 1.4.

This meter can be upgraded to an intelligent metering system (iMSys) according to §21(1) MsbG by means of a pluggable LMN interface.

The DWS76 differs from the DVS76 by the extension to the 1-phase approval for use as an alternating current meter (AC meter). Here an optional factory configuration of up to three phases for L1, L2 and L3 each can be carried out on delivery. Compared to the DVS74 the DVS76 has a limitation max-current 60A and is equipped with cage clamps.

A currentness reading of the meter is also possible without the device being connected to the 3x230/400 mains voltage. The external power supply required for this can be generated on the one hand via a battery source (e.g. powerpack) or a 12V USB interface (e.g. DVS76 programming adapter).

Furthermore, this meter has a wired RS485 interface for reading out the meter data. This is available until a plug-in is inserted. The optional device variant with the Bluetooth interface fully integrated in the meter serves the same purpose.. 

Alternative data interfaces extend its function and make the meter interesting for the distributors of municipal utilities.

PlugIn versions:

  • LMN (according to FNN)
  • LoRa (with integrated wMBus)
  • wMBus
  • RS485
  • Bluetooth

The DVS74 is optionally available with various terminal cover versions:

  • Standard terminal cover (L 100 mm, free space 50 mm)
  • Long terminal cover (L 162 mm, free space 120 mm)
  • Middle terminal cover (L 120 mm, free space 80 mm)
  • Piggyback terminal cover for mounting accessories with three-point mounting (L 162 mm, free space 120 mm)
  • DIN rail terminal cover with module cover (e.g. for the use of a Smart Meter Gateway)

If required, the optional customer interface (flashlight function) can be deactivated at the factory so that only the operating button of the mater can be used to access the historical data.

WS74

Single Phase Electronic Electricity Meter

Electricity meter for active consumption measurement according to §29(3) and §61(3) of the Measuring Point Operating Act (MsbG) of 29.08.2016, as well as FNN specifications “Basiszähler Funktionale Merkmale” Version 1.4.

This meter can be upgraded to an intelligent measuring system (iMSys) according to §21(1) MsbG by means of a pluggable LMN interface.

Alternative data interfaces expand its function and make the meter interesting for the sales networks of municipal utilities.

PlugIn-Versions:

The WS74 is optionally available with various terminal cover versions:

  • Standard terminal cover (L 90 mm, free space 40 mm)
  • Short terminal cover (L 50 mm, free space 0 mm)
  • Long terminal cover (L 135 mm, free space 120 mm)
