The manufacturer recommends the use of an external bubble trap for
flow rates higher than 1.9 LPM (0.5 GPM).
1. Install the external bubble trap vertically (air vent up) and upstream
of the sensor. Refer to the instructions supplied with the external
bubble trap.
2. Make sure that the air vent is open. Bubbles will stay in the liquid
when the air vent is closed.
3. Periodically remove the bubble trap drain plug to let any collected
sediment sludge drain.
