Abstract
Systems, devices, and methods for an unmanned aerial vehicle (UAV); a trace gas sensor disposed on the UAV, where the gas sensor is configured to measure a gas point concentration; a wind sensor, where the wind sensor is configured to determine a discrete wind vector corresponding to the gas point concentration measurement; and where the discrete wind vector and gas point concentration measurement are acquired substantially concurrently and co-locally.
Claims20
A system for determining a gas leak rate, the system comprising:
- a trace gas sensor configured to measure a plurality of gas point concentrations at a plurality of locations;
- a wind sensor configured to determine a discrete wind vector at the plurality of locations;
- and
- a processor configured to:
- determine a flux rate of gas in a surface integral on a flux plane, by multiplying the surface integral by a freestream velocity, wherein the freestream velocity comprises a velocity with which the flux plane is moving through the gas plume.
A system for determining a gas leak rate, the system comprising:
- a trace gas sensor configured to measure a plurality of gas point concentrations at a plurality of locations;
- a wind sensor configured to determine a discrete wind vector at the plurality of locations;
- and
- a processor configured to:
- determine an elevated gas point concentration from among the plurality of gas point concentrations;
- and
- determine a leak rate of the gas plume by determining a flux rate of gas in a surface integral on a flux plane of the gas plume based on the elevated gas point concentration.
