Measure what your business consumes.
The Z series captures electricity, water, heat, gas and compressed air – per machine, hall or rental unit. Remotely read via M-Bus, Modbus and LoRaWAN, analysed in irot software, billing-ready thanks to MID.
The Z series is in development: pilot customers receive pre-series devices on special terms.
One family for every energy type.
Same housing, same protocols, same software – only the measuring core changes. The cabinet stays tidy and the analytics stay uniform.
Z 100 – electricity
Three-phase meter up to 100 A direct or via CT – MID-compliant for sub-metering and billing.
Z 200/300 – water & heat
Cold, hot water and heat meters with wireless readout – leak alarms included.
Z 500 – compressed air
The meter for the most expensive energy in the building: finds leaks and silent consumers in the network.
Z 700/800 – pieces & hours
Piece counters and hour meters turn machines into honest reporters.
Z 950 – gateway
Connects existing third-party meters via M-Bus and Modbus – your legacy becomes part of the system.
Analytics included
Every meter reports to irot software: load profiles, cost per cost centre, CO₂ balance – zero setup.
MID where it counts
Billing-grade measurement under the Measuring Instruments Directive – for subletting, charging points and contracting.
Data stays home
Readout locally, into your own data centre or into your irot cloud instance in Germany – your choice.
Installer-friendly
35 mm DIN rail, pluggable terminals, wiring diagrams in the lid – electricians love it.
From cabinet to chart
Mount
Meter onto the DIN rail, plug the terminals – or use CT clamps with no intervention at all.
Connect
M-Bus, Modbus or LoRaWAN – the gateway discovers every meter by itself and registers it in the software.
Analyse
Load profiles, comparisons and alarms in irot software – from day one, without a project.
