Sat for exactly 12 seconds at 03:17 and the pump in 12B — silent all night — picked that moment to scream AIR IN LINE like it heard my knees bend… Is this a physics thing or does our fleet come with a Sit Detector I missed in orientation?
On slow rates I get the same — backprime a few mL and leave a small ‘U’ loop below the pump to trap microbubbles so it doesn’t hit you with the dramatic ‘AIR IN LINE’; does it happen more under [redacted]/hr or right after a bag swap? Pretty sure mine has a butt-proximity sensor.
