About 10 years ago the PG&E client requested an upgrade of the natural gas pressure regulator operations in the meter shop. ESC provided a manual and automated Retulator Testing Machine (ARTM). ESC was referred to Socal Gas and we povided theri meter shop with a manual as well as an automated ARTM.
Fast forward to 2021, ESC has provided RTMs to many gas utiities in the U.S. and Canada. With the advent of the Internal Relief and Over Pressure Shut Off features, the gas utilities acknowledge that the pressure regulator needs to be in-tested in the meter shop to assure safety to the gas customers.
