1. A system, comprising:
a fuel media supply, configured to provide unodorized fuel media, coupled to:
a media supply injection valve; and
a fuel media supply flow meter;
an odorant supply, configured to provide pressurized odorant, coupled to:
an odorant pressure regulator, configured to provide regulated pressurized odorant, coupled to each of:
a first actuator, configured to allow regulated pressurized odorant flow at a first pressure when enabled;
a manual ball valve, configured to allow regulated pressurized odorant flow to be manually adjusted between no flow and the first pressure when enabled, coupled to:
a manual flow metering valve; and
a second actuator, configured to allow regulated pressurized odorant flow at a second pressure lower than the first pressure when enabled;
a mixture receiver, coupled to the fuel media supply and each of the first and second actuators and the manual flow metering valve, configured to receive odorized fuel media comprising a mixture of the unodorized fuel media and regulated pressurized odorant; and
a control system, comprising:
a processor; and
a memory, coupled to the processor, comprising instructions, that when executed by the processor, are configured to:
initiate production of the mixture;
adjust the mixture with the first and second actuators, in response to the mixture not including a desired concentration of the regulated pressurized odorant; and
terminate production of the mixture.
