What is the primary advantage of using a bourdon gauge flowmeter?

The primary advantage of using a bourdon gauge flowmeter lies in its ability to accurately measure high flow rates. Bourdon gauges work on the principle of changes in pressure, where the bends in a tube uncoil as pressure increases, allowing for precise readings of gas flow. This makes them particularly suitable for situations that require monitoring of high gas flow, such as in respiratory therapy or anesthesia.

Unlike other types of flowmeters which may struggle with high volumes, the design of the bourdon gauge enables it to handle a wide range of flow rates effectively without sacrificing accuracy. This precision is critical in medical settings where proper gas delivery is vital for patient safety and treatment efficacy.

While aspects related to fixed flow rates, self-calibration, and connections to nebulizers might have their own benefits in specific contexts, they do not reflect the unique capabilities of the bourdon gauge in measuring high flow rates.
