Triple bubbler system, fast-bubbling approach, and related methods

A triple bubbler system, comprising:

• a first fluid probe configured to be at least partially submerged within a fluid;
• a second fluid probe configured to be at least partially submerged within the fluid;
• a third fluid probe configured to be at least partially submerged within the fluid;
• a gas source operably coupled to the first fluid probe, the second fluid probe, and the third fluid probe and configured to meter gas through the first fluid probe, the second fluid probe, and the third fluid probe to form bubbles at tips of each of the first fluid probe, the second fluid probe, and the third fluid probe;
• a thermocouple comprising a plurality of junctions disposed along an axis at least substantially parallel to longitudinal axes of the first fluid probe, the second fluid probe, and the third fluid probe, wherein at least one of the junctions is configured to be submerged in the fluid, and wherein at least one of the junctions is configured to be disposed above the fluid;
• and
• a controller operably coupled to the gas source and the thermocouple and comprising:
• at least one processor;
• and
• at least one non-transitory computer-readable storage medium storing instructions thereon that, when executed by the at least one processor, cause the controller to:
• receive temperature data from the plurality of junctions of the thermocouple;
• and
• based on the received temperature data, determine a temperature profile along the axis along which the plurality of junctions are disposed.

A method of measuring fluid characteristics within a turbulent fluid, the method comprising:

• metering a gas through each of a first fluid probe, a second fluid probe, and a third fluid probe at a rate of at least 30 cc/min and into a fluid;
• measuring bubble pressures of each of the first fluid probe, the second fluid probe, and the third fluid probe caused by the metered gas and via differential pressure transducers;
• and
• based at least partially on the measured bubble pressures of each of the first fluid probe, the second fluid probe, and the third fluid, determining a density, a surface tension, and a depth of the fluid.
