Airflow Measurement: Air Monitor
Air Monitor’s ELECTRA-flo/SD is a thermal airflow and temperature measurement system designed for applications in small ducts ranging in size from 4-in to 16-in diameter. The product provides a calibrated output with an accuracy of ±2-3% of airflow reading from 0-3,000 FPM and a temperature measurement accuracy of ±0.15 ̊ F.
To maximize application flexibility, the ELECTRA-flo/SD transmitter has four different user selectable flow velocity ranges and four user selectable flow filter settings. Flow can be reported in FPM or as the equivalent velocity pressure (inches of w.c.). The ELECTRA-flo/SD may be ordered with dual analog outputs for flow and temperature or with an RS485 output for BACnet® MS/TP or Modbus® RTU.
