Morphology
The meaning 'an instrument used to measure the rate at which a liquid or gas flows' is directly derived from combining 'flow' (movement of liquid/gas) with 'meter' (measuring instrument). This noun–noun compounding is a common, compositional pattern in English and other languages, so a B1 learner who knows both constituents will readily infer the meaning.
Etymology
Flow meter comes from the words flow, meaning the movement of a liquid or gas, and meter, meaning a device that measures. The image is of a small device watching how fast water or air moves through a pipe, so flow meter means 'an instrument that measures how fast a liquid or gas moves'.
