FP-25–Field Flow Standards for PM Air Samplers

Accurate air flow calibrations in any weather

Audit flow rate, pressure and temperature with laboratory-grade accuracy in an instrument that won’t break down. Alicat’s FP-25 and FP-25BT (with Bluetooth) flow standards calibrate every low-volume particulate air sampler on your deck. All-weather accuracy and durability ensure consistent readings, no matter the wind, temperature or humidity.

  • All-Weather Accuracy. Be confident in your flow measurements, no matter the weather. Responsive temp probes and humidity sensors keep the weather in check as you monitor flow, pressure and temperature in real time. Or, collect a robust average of 5000 readings in 5 seconds.
  • Fast & Easy Operation. Climb ladders less with Bluetooth connectivity (FP-25BT only). Connect quickly to any low-volume sampler with the industry’s only pass-through PM10/PM2.5 inlet connection. Or use the included barb fitting with face seal for no-hassle fitting changes. Rapid temperature equilibration lets you get started right away.
  • Durable Field Design. Keep calibrating after a drop from the roof, or finish your audit if it starts to rain. This compact calibrator fits in your pocket but is built tough with an all-aluminum body, weather-resistant connections and the industry’s only lifetime warranty.


Performance

  • Flow range: 0.125-25.000 lpm/slpm
  • Flow accuracy: +/- 1% of the reading (NIST-traceable)
  • Barometric pressure accuracy: +/- 1 mmHg (NIST-traceable)
  • Temperature probe accuracy: +/- 0.2 ºC (NIST-traceable)
  • Pressure drop: 0.10 psi at 16.7 lpm, 0.16 psi at 25.0 lpm
  • Typical flow reading response time constant: 5 ms (may be up to 10 ms under very low flow conditions)
  • Typical temperature and humidity equilibration: less than 5 minutes

Operating Conditions

  • Compatible gases: ambient air only
  • Operating temperature: -30°C to +60°C
  • Ambient pressure: 475-825 mmHg
  • Max internal pressure (static): 45 psig (60 psia)
  • Max differential pressure (inlet to outlet): 15 psid
  • Proof pressure: 175 psig (190 psia)
  • STP/NTP: user-selectable (defaults to 25°C & 1 atm STP/0°C & 1 atm NTP)

Alicat FP-25 flow calibrating a rooftop Met One BAM 1020/1022 FEM air sampler

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.
