Method 1: Direct Mode

Direct Mode connects the Alicat FP-25 directly to your sampler’s downtube. The pass-through connection most closely replicates sampler operating conditions. The low pressure drop of the Alicat ensures that it is virtually invisible to your air sampler.

  1. Thread the Direct Mode downtube adapter into the outlet of the FP-25 until its face seal is tight against the flow body.
  2. Thread the Direct Mode PM inlet adapter into the inlet of the FP-25 until its face seal is tight against the flow body.
  3. Fit the FP-25 onto the BAM downtube, and place the PM10 inlet on top of the FP-25. If using a PM2.5 cyclone, leave it in place, and fit the FP-25 between it and the PM10 inlet.
  4. Insert the FP-25 external temperature probe into the sampler’s radiation shield.
  5. Be sure to tare the Alicat FP-25 before you begin the BAM 1020 or BAM 1022 flow calibration.

Method 2: Standard Mode

Standard Mode connects the FP-25 to any air sampler by means of a hose barb and silicone tubing. FRM and FEM samplers will use their flow audit adapters for this setup.

  1. Thread the barb fitting into the outlet of the FP-25 until its face seal is tight against the flow body.
  2. Push the silicone tubing onto the barb.
  3. Fit the other end of the tubing onto the barb of the BAM flow audit adapter.
  4. Place the flow audit adapter onto the top of the BAM downtube, or the PM2.5 cyclone if you are using one.
  5. Insert the FP-25 external temperature probe into the sampler’s radiation shield.
  6. Be sure to tare the Alicat FP-25 before you begin the BAM 1020 or BAM 1022 flow calibration.

Pressure monitoring during external leak checks

The pass-through setup (Direct Mode) can also be used to provide pressure monitoring during leak check procedures. During the leak check, monitor internal pressure with absolute or gauge reference in the engineering unit of your choosing.

  1. Thread the Direct Mode downtube adapter into the outlet of the FP-25 until its face seal is tight against the flow body.
  2. Thread the Direct Mode PM inlet adapter into the inlet of the FP-25 until its face seal is tight against the flow body.
  3. Fit the FP-25 onto the BAM downtube.
  4. Fit the leak check adapter onto the PM inlet adapter of the FP-25.
  5. Select gauge or absolute pressure on the FP-25 to monitor sampler pressure during the leak check.
