The Pump details screen opens, displaying pump status, tubing length, flow rate, and sample time (if enabled).

Pump details screen example
Note:

Flow rate is the speed that air is passing over your device’s sensors. To provide accurate gas readings, flow rate needs to be above 150 ml/min. A flow rate less than 150 ml/min results in a pump block notification.

By default, Blackline's pump aims to maintain a flow rate of 300 ml/min and G7 automatically adjusts its pump speed to maintain this rate.
