Air Sensor Tubing Length and Bubble Size
The response of the air sensor module is highly dependent on the bubble size and
flow rate, and requires a minimum tubing length between the sensor outlet and the
pump inlet. Table 6 lists recommended tubing lengths for various flow rates and
bubble sizes.
1 ml/min 15–25 μl ≥6"
5 ml/min 50–100 μl ≥6"
10 ml/min 200 μl ≥6"
100 ml/min 1.05–1.4 ml ≥42"
