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.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.
DVSB / DWSB
Electronic three-phase meter / smart meter Metering System-2020
The first generation of electronic three-phase meters in the DVSB series is manufactured in accordance with FNN smart meter specifications (version 1.4.1). In accordance with the EnWG, these meters can be used as a measuring device alongside a BSI-compliant smart meter gateway to form an intelligent measuring system (iMSys). Alternatively, they can be used individually as a modern measuring device (mME) where the installation of an iMSys is not mandatory.

The DVSB is optionally available with a double-tariff counter that can be controlled via terminals.
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.
- LMN (according to FNN)
- 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)
- Long terminal cover (L 162 mm, free space 120 mm)
- Middle terminal cover (L 120 mm, free space 80 mm)
- Long terminal cover punched out (length 162 mm, clearance 120 mm, for piggyback mounting of additional devices)
- 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.
WS76
Single Phase Electronic Electricity Meter.
Legally compliant electricity meter for active consumption measurement in accordance with §29(3) and §61(3) of the Measuring Point Operation Act (MsbG), as well as FNN specifications“Basiszähler Funktionale Merkmale” version 1.4. This meter can be upgraded to an intelligent metering system (iMSys) in accordance with §21(1) MsbG using a pluggable LMN interface.
