Metering and regulating stations ensure the safe and efficient delivery of natural gas to customers. Some are located at the city gate stations or at very large customer facilities, although most are located throughout the system. These stations reduce pipeline pressures, allowing gas to be delivered safely through the distribution system within the maximum allowable operating pressure.
If odorant is not present in the gas, odorant injection systems add odorant to the gas stream at the metering and regulating stations. This gives natural gas a strong sulfur-like or rotten-egg smell that helps people detect leaks.
Metering and regulating stations always have inlet and outlet shutoff valves. Never open or close these valves. Only trained technicians are permitted to operate them.
