190.00 + VAT

The PA-FL wireless pulse counter has been designed for counting meter pulses. One PA-FL can read pulses from one utility meter. The PA-FL pulse counter has both 24V and battery power supply options. Battery power supply is ideal in situations where the PA-FL is mounted in a remote location e.g. read the water meter readings.

The PA-FL wireless pulse counters work as a part of the SyxthSense wireless solution. With the PA-FL it is now possible to combined the building monitoring/automation and the meter readings to a single system. The PA-FL provides reliable pulse transmission as it sends the actual pulse count wireleslly over the network. Should the transmission not succeed the value is re-transmitted to the FLTA receiver.


  • Perfect for remote meter monitoring
  • 24Vac power supply and/or battery power supply
  • For heat, water, electricity and gas meters
  • Values read over Modbus via FLTA base station
  • Adjustable counting pre-scaler
  • Data back-up with the batteries
  • Remote low battery indication / alarm

Application Example:-

The PAFL wireless pulse counters are linked to the pulse meters. The PAFL counts the pulses and transmits the pulse count to the FLTA base station. The pulse count is then read via Modbus to the Modbus master e.g. SDC-30 controller.
