What is the kPa gauge for gas meter?
Gas meter piping supplying gas to a building at a pressure in excess of 1 / 2 psig (3.4 kPa gauge) shall be provided with a regulator that will reduce the pressure of the gas to 1 / 2 psig (3.4 kPa gauge) or less prior to entering the gas distribution piping in the building, except where the use of higher pressure is permitted. Where gas distribution pressure in excess of 1 / 2 psig (3.4 kPa gauge) is permitted, it shall be regulated not to exceed the maximum pressure level as permitted by the code or the commissioner.
