TL;DR
Clocking the gas meter is the technique of timing the utility meter's test dial while a single appliance runs to calculate its actual fuel input in BTU per hour. With all other gas loads shut off, the technician counts seconds per revolution of the half-foot or two-foot dial and converts using the gas heating value.
What it means
Clocking the gas meter is the technique of timing the utility meter's test dial while a single appliance runs to calculate its actual fuel input in BTU per hour. With all other gas loads shut off, the technician counts seconds per revolution of the half-foot or two-foot dial and converts using the gas heating value. It verifies that a furnace or water heater is firing at its nameplate rate, catching undersized orifices, regulator problems, or altitude-related underfiring during commissioning.
