enLink Status-AF – LoRa Wireless Air Velocity Sensor

enLink Status-AF measures air velocity in the range of 0 to 40m/s with industry leading accuracy of 0.1% of selected range. Unique Multi-Range digital sensor allows multiple ranges to be selected automatically or remotely.

This sensor can be used to ensure that recommended air flow rates for public buildings and industrial plant are achieved.

Air velocity data is automatically transmitted to the cloud using long range LoRa wireless where the device data can be displayed and analysed to reveal operational performance and generate alerts.

Sensor Characteristics

  • Range: 0 to 40m/s
  • Long term stability ±0.1% FSS
  • Exceptional Zero Stability
  • Selectable bandwidth filter
  • Up to 7 Calibrated ranges
  • Accuracy: 0.1% per range
  • Integrated 50/60Hz filter
  • Temperature compensated

Long life battery power enables simple, low cost installation for a variety of applications.

Unique Multi-Range sensor has up to 7 calibrated ranges for unrivalled dynamic range, with the benefit that a single Status-AF unit can cover the full air velocity requirements of HVAC and other applications.

Long range LoRa wireless transmits the data for up to 16 km with deep in building penetration of 1 – 3 km without repeaters.

Data can be received by any LoRaWAN compliant gateway or enLink Hub to forward data to the Cloud where it can be analysed using enVision or third party applications.

When used with enLink Hub, sensor data can be sent via long range LoRa wireless and converted to Modbus IP register values for integration with EMS/BMS, SCADA or monitoring equipment.
