Natural gas pressure regulator in-testing in the meter shop has been considered for years. Today, in-testing needs to rise to the challenge and emphasis of customer safety and billing accuracy. That means using the state-of-the-art methods and technology.
For example, Fortis Energy uses the Regulator Testing Machine (RTM) to assure that all gas service pressure regulators protect the customer from potential over pressure situations as well as accurately measure the amount of gas delivered.
This protection begins with the gas utility specifying, to the manufacturer, the required regulator performance and the criteria for "assuring" the requirements are met. It ends with the gas utility in-testing the regulator in the meter shop to "control" the quality of each regulator and to assure the customer safe and accurate natural gas service.
Of course, not all gas utilities use the in-testing methodology. However, modern technology and safety concerns challenge all gas utilities to think differently and to consider new ideas and ways of doing things.
