What is the purpose of a second stage regulator during gas distribution?

The purpose of a second stage regulator in gas distribution systems is to reduce the maximum operating pressure (MOP) down to a safer, lower distribution pressure suitable for end-user consumption. In a gas distribution framework, the gas might be transported at high pressures through pipelines. The second stage regulator ensures that before the gas reaches consumers, it is at a manageable pressure level that meets safety standards and operational efficiencies.

By accurately regulating the pressure, the second stage regulator prevents over-pressurization within the distribution system, which could lead to safety hazards or equipment damage. This function is critical in ensuring that natural gas is delivered safely and efficiently to residential and commercial users.

The other choices relate to aspects of gas distribution but do not accurately describe the specific role of a second stage regulator. Measuring gas flow involves different instrumentation, regulating temperature is not the main function of the regulator, and while eliminating gas leaks is crucial for safety, it is not a direct function of the second stage regulator.
