Abstract

A system is provided. The system includes one or more of a fuel media supply, coupled to a media supply injection valve and a fuel media supply flow meter, configured to provide unodorized fuel media, an odorant supply, configured to provide pressurized odorant and coupled to each of a first actuator to allow odorant flow at a first pressure, a second actuator to allow odorant flow at a second pressure, and a manual ball valve, a mixture receiver, coupled to the fuel media supply, each of the first and second actuators, and a 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, configured to initiate production of the mixture, adjust the mixture with the first and second actuators, in response to the mixture does not include a desired concentration of the odorant and terminate production of the mixture.

Dependent claims

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.
