The Open Metering System (OMS)

The Open Metering System (OMS) is the only system definition across Europe which integrates all media (electricity, gas, heat and water incl. submetering) into one system. It was developed by the industry to guarantee a future-proof communication standard and interoperability between all meter products.  Ref:

Lansen supports the OMS specification for both Wireless M-Bus and Wired M-Bus to deliver products with long lifetime, long transmission range and verified *interoperability. The Wireless M-Bus standard is defined in EN 13757 and the interoperability is guaranteed in the OMS specification. Furthermore, the OMS/Wireless M-Bus stack is developed inhouse for best performance, battery life and reliability.


All Lansens sensor have been tested with the OMS conformance tool.
