Through the implementation of a barometric pressure sensor, thermocouple, precision machined venturi tube and differential pressure sensor, HI-Q’s DFMC-SD-SMS series microprocessor-based air flow calibrators are used to measure, record & display instantaneous flow rate, temperature and barometric pressure. Through onboard calculations, the user may also select to display the flow rate and total volume in actual or standard units. The processor also includes a removable micro SD card that logs the data at a user-settable frequency. These logs can be downloaded to a PC as a csv file (comma separated values). The processor and an onboard GSM modem (activated on user’s cellular account) is configured to send SMS messages during power failure and at other user-programmable events such as low-flow rate, and high-flow rate. This unit can be configured for existing air sampling stations.
