What is a Monitor Regulator used for?

A Monitor Regulator is specifically designed to ensure the proper operation of a primary regulator and to monitor its performance. It serves as a safety device that continually assesses the output pressure to ensure that it remains within safe operational limits. If the primary regulator fails or deviates from the intended pressure, the Monitor Regulator can initiate actions to maintain safety and reliability in the gas delivery system.

By focusing on monitoring, this type of regulator plays a crucial role in preventing overpressure situations and ensuring the continued efficient operation of gas appliances and systems. Thus, its primary function aligns closely with monitoring the performance and integrity of the system rather than adjusting the pressure or flow directly, which distinguishes it in function from other types of regulators that are designed for pressure increases, flow reduction, or emergency shut-off operations.
