To resolve flow issues with the Met One Instruments BAM 1022, follow these steps:

1. Check for Air Pump Wear – If the airflow does not regulate at 16.7 lpm, the air pump may be losing vacuum capacity. Perform a flow calibration to confirm.

2. Inspect for Leaks – Check for leaks at the nozzle, as leaks can cause low inlet flow despite the correct sensor reading. Clean the nozzle and vane.

3. Replace the Pump Muffler – The gray plastic pump muffler clogs after several months, reducing vacuum capacity. Replace it every six months.

4. Examine the Inlet and PM Heads – Ensure there are no obstructions in the inlet or PM heads that could restrict airflow.

5. Perform Leak Checks – If leaks persist after cleaning, verify that the nozzle is not sticking. Conduct a basic leak check and, if necessary, follow the Advanced Leak Check procedures in section 6.3 of the manual.

Following these steps should help resolve flow regulation issues.

The BAM 1022 can be integrated with a real-time air quality data platform via API by using its Ethernet communication capability. To do this:

1. Assign a static IP address to the BAM 1022 as described in the manual.
2. Set the baud rate to 38400 and Ethernet Flow Control to RTS/CTS in the Serial Port menu.
3. Connect the BAM 1022 to the local network using a CAT5 Ethernet cable.
4. Use appropriate software to access the data through the assigned IP address.

Once connected, data can be retrieved and forwarded to an API for real-time monitoring.

  • Page 33: Warm-Up Period

    Warm-up Period If the BAM 1022 has been switched off for more than a few moments, the mass monitor must warm up for at least one hour before accurate PM measurements can be obtained. This is because the beta detector must stabilize. Users are encouraged to disregard the first two hourly PM data sets after power is restored.

  • Page 34: The Bam 1022 Measurement Cycle

    Short Term Averaging The BAM 1022 always reports the hourly PM concentration at the top of the hour. Given that the measurement occurs in real time, hourly results may be supplemented with shorter term data.
