Wireless M-Bus metering modules for smart water and gas meters, combining non-magnetic inductive sensing with 868 MHz EN 13757 / OMS communication. Three PCB formats — V23050, V11201 and V20525 — share one electrical and RF platform and are adapted to different meter mechanisms. Designed for remote meter reading in AMR/AMI systems.
The WMBus metering module series integrates PCB-coil non-magnetic sensing with a Wireless M-Bus radio compliant with EN 13757 / OMS. It detects the rotation of a metal target without reed switches or Hall elements, so metering is unaffected by strong external magnets. Data is transmitted at 868 MHz in configurable T1 / C1 mode to a W-MBus receiver or concentrator for remote reading of water and gas meters.
V23050-WMBUS, V11201-WMBUS and V20525-WMBUS cover the three PCB formats used across our water and gas meter range. All models share the same 2.9–3.6 V supply, metering and RF specifications; PCB outline, connector and cable are customized to the meter mechanism.
Send interval, encryption method and key, operating mode and transmit power are configured over the infrared port. Meter serial number, internal time and forward / reverse flow settings are also configurable. Contact us with your meter type, PCB envelope and reading network requirements.
