Electricity metering today works in an intelligent way. With our electronic electricity meters (modern measuring devices), we are responding to the digital energy transition and are in line with the Forum Netztechnik/Netzbetrieb (Network Technology/Network Operation Forum) and the FNN specifications.
The new smart meters have numerous advantages over the old electromechanical meters: for example, higher measuring accuracy, enhanced protection against manipulation, lower power consumption and self-monitoring.
The modern light measuring devices from DZG-Metering in the 3Hz household meter design, which can be upgraded to an intelligent measuring system using a retrofittable LMN interface, meet the requirements of the FNN specifications in version 1.4 for three-phase and single-phase connections.
Important note for end consumers: The electricity meter is the property of your network operator. Please contact them directly if you have any further questions about your electricity meter and a functional upgrade.
DVSB.G3 / DWSB.G3
Electronic three-phase meter / basic meter MessSystem-2020 in accordance with FNN specifications Basic meter Functional features, version 1.4.1 with integrated wireless MBus interface with Mode 7 encryption and compact profile for TAF7.
The third generation of the DZG basic meter can also be used as an intelligent measuring system (iMSys) with a BSI-compliant smart meter gateway SMGw. The use of a wireless MBus interface with Mode 7 encryption and compact profile enables easy integration of the DVSB.G3. A wired connection according to FNN is also available.
Use as a modern measuring device (mME) is also possible below the installation obligation for iMSys. As a further optimisation compared to Generation 1, the terminal block has been designed with cage clamp terminals.
The basic meters of the DZG are currently available in the direct-measurement version for SLP measurement as type DVSB.G3. The DVSB.G3 is available as an option with additional approval for single-phase operation (L3) in the DWSB.G3 version. All versions of this meter type operate with phase balancing.
Due to the direct connectivity via wireless MBus with Mode 7 encryption and compact profile, the DVSB.G3 and DWSB.G3 do not have a tariff register.
DVSB.G2 / DWSB.G2
Electronic three-phase meter / smart meter Metering System-2020 of the second generation
The DVSB.G2 series of electronic three-phase meters is manufactured in accordance with FNN specifications for smart meters, version 1.4.1. The second generation of the DVSB has been specially optimised for use with a BSI-compliant smart meter gateway as part of an intelligent measuring system (iMSys). It can also be used as a modern measuring device (mME) in areas where the installation of an iMSys is not mandatory. Compared to Generation 1, the terminal block has been further optimised with the addition of cage clamps.
DZG's smart meters are currently available in a direct-measuring version for SLP measurement, designated as the DVSB.G2 type. The DVSB.G2 is also available as DWSB.G2 variant, which has additional approval for single-phase operation (L3). Everything else aligns with the DVSB.G2. All variants of this meter type are phase-balancing.
DVZE.G3 / DWZE.G3
Electronic electricity meter / eHz design in accordance with FNN specifications Basic meter Functional features, version 1.4.1, in eHz design with integrated wireless MBus interface with Mode 7 encryption and compact profile for TAF7.
This basic meter is suitable for measuring points with plug-in technology. The use of a wireless MBus interface with Mode 7 encryption and compact profile enables easy connection of the DVZE.G3 to a smart meter gateway SMGw without additional cabling. A wired connection with a suitable OKK according to FNN is also possible.
According to the German Energy Industry Act (EnWG), this meter is used as a measuring device together with a BSI-compliant smart meter gateway as an intelligent measuring system (iMSys) or individually as a modern measuring device (mME) below the installation obligation for iMSys. All variants of this meter type operate with phase balancing. The DVZE.G3 is an AC four-wire meter for direct connection.
The DVZE.G3 is available as an option with additional approval for single-phase operation in the DWZE.G3 variant.
DVZE.G2 / DWZE.G2
Electronic electricity meter/eHz design
The DVZE.G2 series of electronic three-phase meters is manufactured in accordance with FNN specifications for smart meters (version 1.4.1). This smart meter is designed specifically for use in measuring stations with plug-in technology.
According to the German Energy Network Act (EnWG), it can be used as a measuring device in conjunction with a BSI-compliant smart meter gateway to form an intelligent measuring system (iMSys). Alternatively, it can be used individually as a modern measuring device (mME) where the installation of an iMSys is not mandatory. All variants of this meter work with phase balancing.
The DVZE.G2 is a four-wire meter for direct connection to alternating current. The DVZE.G2 is also available as an option with an additional approval for single-phase operation (L3) in the DWZE.G2 variant. Everything else aligns with the DVZE.G2.
DVS76 / DWS76
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 is limited to a maximum of 60 A. It is equipped with cage clamp terminals. All variants of this meter type work with phase balancing. The meter can also be read without the device being connected to the 3x230V/400V mains voltage. The required external power supply can be generated via a battery source (e.g. a power pack) or a USB interface (e.g. the DVS76 programming adapter). Furthermore, this meter has a wired RS485 interface for reading the meter data. This is available until a plug-in is connected. Alternative data interfaces extend its function and make the meter interesting for the suppliers' sales departments.

- LoRa (with integrated wMBus)
- wMBus
- RS485
The DVS76 is optionally available with various terminal cover versions:
- Standard terminal cover (L 100 mm, free space 50 mm)
