A flow meter is an essential device in a medical gas system, primarily designed to measure the rate of gas flow being delivered to a patient. This measurement is crucial because it helps healthcare professionals ensure that patients receive the appropriate volume of gas needed for their treatment.

Flow meters are calibrated to indicate how much gas is flowing through the system, typically measured in liters per minute (L/min). By providing real-time data about the flow rate, medical staff can adjust the settings according to the patient's requirements, ensuring safe and efficient administration of medical gases.

The other options detail functions that are not attributed to a flow meter. For instance, measuring the pressure of the gas is the role of a pressure gauge, while controlling temperature is not a function of the flow meter at all. Regulating oxygen levels in a room involves different systems and mechanisms unrelated to flow measurement directly. Thus, the correct choice accurately reflects the primary purpose of a flow meter within medical gas systems.
