The ENBRA NAXOM OP-O4-1a radio module is designed exclusively for ENBRA ER-AM DN 20 residential water meters and ensures wireless transmission of measured values using the Wireless M-Bus protocol within the OMS system. It allows for both walk-by and stationary readings without the need to enter apartments or buildings.

The module can be easily fitted to the water meter even after installation, but parameterization is required. The integrated long-life battery and memory for monthly readings up to 16 months in advance support reliable consumption monitoring, including water leak detection and unauthorized tampering with the water meter.
