F&J Digital Flow Meter System

The F&J Digital Flow Meter system makes on a once per second frequency measurement of air flow temperatures and pressures to determine flow rates and volumes normalized to an internationally recognized standard of temperature and pressure.

The F&J Digital Flow Meter displays on a bright LED display the flow rate, the elapsed time of the sample event and the accumulated sample volume.

The operator can make the following selections via the setup process utilizing the key pad.

  1. Normalization of the flow rate and volume to a pre-selected reference temperature and pressure, or to ambient conditions
  2. Automatic Shut off on time or on volume, or for continuous sampling until a manual termination is executed by the operator
  3. RS232 output frequency to a computer or to an optional F&J storage device.

The F&J Digital Flow Meter system can be integrated with the optional F&J Storage Device, or with a ruggedized cellular phone system capable of providing alarm warnings for loss of power, low or high flow, low or high pressure and temperatures, and excessive dust loading. Alarm conditions are operator selectable. Alarm information can be provided to as many as three persons via text messaging or email.
