Sensus PulseRF module allows you to integrate meters with a pulse output into the Sensus RF radio system. It is mainly used with C&I water meters, but can also be used with thermal energy, gas and electricity meters.It is designed to transmit meter data frequently or on request to mobile readout devices, or to a Sensus RF fixed radio network. The PulseRF module creates data out of incoming pulses and transmits them to an external data management system (such as a meter index, alarms or additional information as Fixed Date Reading or data logger). In addition to transmitting the meter index, the module has numerous smart functions that provide added customer value.
