Sensus CompactRF Radio Module


The Sensus CompactRF radio module can be retrofitted to Sensus residential water meters that are prepared for an HRI pick-up system.

This clip-on module integrates mechanical meters into the SensusRF radio system.

CompactRF modules are designed to securely and automatically transmit the most important meter data at frequent intervals or to enable more detailed information, using mobile data collection devices or a fixed radio network. Besides improved meter reader safety, the utility will be able to gain in operational efficiency.

In addition to providing the meter index, CompactRF modules enable numerous other smart functions, supporting customer satisfaction programs, and NRW initiatives.
