Through the implementation of a baro-metric pressure sensor, thermocouple, precision machined venturi tube and differential pressure sensor, HI-Q’s D-AFC- Series microprocessor based air flow calibrators are used 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 (resettable) 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 spread-sheet 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 the ability to print in textual and bar code format.
