Fluid quantification instrument and method

A fluid quantification method, comprising:

• receiving, using one or more sensor probes of a fluid quantification instrument, one or more raw fluid measurements;
• processing, using meter electronics of the fluid quantification instrument, the one or more raw fluid measurements using a predictive system model to produce one or more optimized fluid measurements, wherein to produce the one or more optimized fluid measurements comprise filtering the one or more raw fluid measurements by selecting a set of sample points from the one or more raw fluid measurements and using the selected set of sample points to capture a mean and covariance of an output of the processing, wherein the processing comprises comparing the one or more raw fluid measurements to at least one fluid measurement predicted using the predictive system model to generate at least one error value and comparing the at least one error value to an error value threshold;
• automatically managing power consumed by the fluid quantification instrument by adjusting a fluid measurement interval based upon the comparison of the at least one error value to an error value threshold, wherein the adjusting comprises decreasing the fluid measurement interval if the at least one error value is greater than the error value threshold;
• and
• determining, using the meter electronics of the fluid quantification instrument, one or more fluid quantifications using at least the one or more optimized fluid measurements, wherein the one or more fluid quantifications comprise a fluid measurement indirectly measured via calculation from the one or more optimized fluid measurements.
