Flow Rate Requirements and Sampling Performance
Maintaining a stable sample flow rate is critical for accurate
gas detection and proper pump operation. Low flow rates can delay
sampling or prevent gas readings from updating properly.
EXO expects a normal flow rate of approximately 300 mL/min during sampling.
If the flow rate drops below 150 mL/min, EXO may trigger a Pump Blocked notification.
Conditions that can reduce the effective flow rate include:
Long or narrow tubing.
Kinked, crushed, or obstructed tubes.
Dirty or clogged pump inlet filters.
Operation in cold temperatures below -20°C (-4°F).
Regularly inspect tubing and inlet connections to maintain optimal pump performance.
