Aeroqual AQM60 User Guide
Note 1: If you are measuring the flow rate through the Ozone module, be aware that the Ozone
module pump cycles on and off about every thirty seconds. Wait for the Ozone module pump to turn
ON before taking a measurement.
Note 2: The ozone module has two inlet connections; bypass inlet and gas inlet. These inlets are
labelled clearly on the module. If the flow is measured at the connection to the manifold the flow will
be continuous.
Verify that the module flow rates are within the expected levels as shown in the table below.
Note 3: The sum of the module flow rates should be equal to the sample inlet flow rate.
