D-AFC-Series: Digital w/ Communication Options

The "All-In-One" Digital Air Flow Calibrator

Through the implementation of a barometric pressure sensor, thermocouple, precision machined venturi tube and differential pressure sensor, HI-Q's D-AFC- Series microprocessor based air flow calibrators are useds to measure, record, & display instantaneous flow rate (i.e.: CFM, LPM, or CMH), temperature (degrees C or F), and barometric pressure ("Hg or mm Hg). Through onboard calculations the user may also select to display the flow rate or total volume in "Standard Units" (ie: SCFM, SLPM, SCMH or SCF, SL, SCM). The total volume of air sampled is displayed (re-settable) in standard and actual units. The processor also has an internal memory that can be programmed for logging and time stamping the instantaneous flow rate, barometric pressure, and temperature. The data can be downloaded to an excel spreadsheet using a PC or a laptop computer. Networking and communications options include two (selectable) RS-232/RS-485 ports, a 4-20 mA and/or 0-10 VDC analog output (proportional to flow rate), the ability to send & receive SMS messages to/from any CDMA/GSM cellular phone (for possibly alerting/reporting any predefined event via text message), remote or local data acquisition and a custom remote data access utility that allows the user to view the display of the unit from a remote location.

  • Flow Rate - Instantaneous Display of actual & standard flow rate (ACFM, ALPM, ACMH, SCFM, SLPM, SCMH)
  • Flow Totalizer- Instantaneous Display of total flow in actual & standard units (ACF, AL, ACM, SCF, SL, SCM, SCMH)
  • Temperature Sensor- Measurement & display of temperature of inline air flow (degrees F & C)
  • Barometric Pressure Sensor - Measurement & display of barometric pressure (in Hg & mm Hg)
  • 110-240 VAC Powered
  • Display - Illuminated graphic LCD screen
  • Data Logger - Internal memory for data logging. Data downloadable to PC/Laptop computer.
  • Data Output - Optional analog 4-20 mA or 0-10 VDC scaled output
