F402 Ideal for Monitoring Water Flow / Consumption

  Buy AUD 178.00

Applications:
  • The dataloggers F412 and F812 have been designed for monitoring physical values where energy consumption and battery life is critical.
  • Accurate monitoring of flow meters and water flow/consumption during short time intervals.
  • Multiple point temperature monitoring.
  • Small low cost monitoring stations for environmental parameters, meteorological data, water level, water flow and other parameters.
  • Areas where vandalism or theft prevents using solar panels.
  • Acquisition situations requiring flexibility and control of external devices or sensors by the datalogger.
  • Applications requiring recurrent remote download by modem or radio-modem.
  • The datalogger can be employed outdoor and indoor.
  • The 12-bit resolution guarantees a resolution 16 times higher than 8-bit products commercialised by competition, making the use of Geosignal dataloggers ideal for detailed acquisition.
