What is the primary purpose of an oxygen regulator?

The primary purpose of an oxygen regulator is to regulate the flow of oxygen from a tank to ensure that a controlled amount of oxygen is delivered to the user or medical equipment. This is crucial because high-pressure oxygen in a tank needs to be reduced to a lower, manageable pressure that is safe for use. Regulators adjust the flow rate to meet the requirements of the specific application, whether it be in a medical setting for patients requiring supplemental oxygen or in various industrial applications.

Monitoring levels, storing oxygen safely, and measuring pressure are important parts of working with oxygen tanks, but they do not encompass the primary function of a regulator. The regulator's role is specifically to control and manage the flow rate, which is essential for effective and safe oxygen delivery.
