Sensus RF Pulse

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.

To connect Sensus PulseRF to a meter with pulse

unit we recommend: Jointing sleeve IP 68, order no. 18 17 84

Connector IP68 for two cables up to 5 wires

Pulse Interface

Meters with a pulse output, as open collector or reed switch, can be

connected. The Sensus PulseRF has one 4 wire input enabling the following


  • Pulse input (+) (white)
  • Cable cut (green)*
  • Direction (yellow)*
  • Ground (-) (brown)

Configuration interface

The transponder can be configured using SensusRF radio with SIRT and configuration software.

Activation via radio or automatically through first 10 pulses.


  • Meter ID
  • Meter Reading
  • Alarms (leak, cable cut*, reverse flow*, broken pipe, internal errors, low battery)
  • Fixed Date Reading
  • Data Logger

* Depending on the connected pulse device Assembly versions

For Sensus mechanical water meters prepared for HRI or HRI-Mei pick-up an assembly with connected pulser exists.
