Which device is used to measure the volumetric flow rate of medical gases through a piping system?

• A. Flowmeter
• B. Regulator
• C. Oxygen concentrator
• D. Gauge

Answer: (A)

Measuring how much gas moves through a piping system requires a device that directly reads flow. A flowmeter does that by letting gas pass through a calibrated element and displaying the volumetric rate, usually in liters per minute, so you can see exactly how much gas is being delivered. In medical gas setups, flowmeters are the point-of-use readouts you rely on to set and monitor the amount of gas reaching a patient. Regulators control pressure, not the amount flowing. An oxygen concentrator is a source that generates oxygen, not a measuring instrument. A gauge typically measures pressure rather than flow, so it doesn’t tell you the volumetric rate.
