5.1 Model 32311 Flow Meter
A flow meter is available as an option, to attach to the top of the flow chamber, instead of
the flow rate adjustment valve usually supplied. This can be used to set an accurate flow
rate of the sample. This is especially useful with small volume packages such as small
cans and bottles.
This flow meter simply replaces the standard adjustment valve, as illustrated in Fig 5-1
below.
If using this flow meter option, you must ensure that you first recalibrate the instrument
with the flow meter attached before you take any measurements. In addition, any
measurements made must be made using exactly the same flow rate setting as used for
the calibration.
The recommended flow rate should be set at 50%, though a minimum flow rate (for small
volume packages) of 30% can be used. To set the flow rate, adjust the knob at the top of
the flow meter until the center point of the bead indicates the desired flow rate.
