Abstract
An automatically compensated fluid flow sensor uses chemometric analysis to produce a compensated fluid flow measurement. A compensation measurement having at least one additional measurement, such as a measurement of thermal conductivity, electrical conductivity, pressure or density can be used to augment the fluid flow measurement in order to compensate for errors in the fluid flow measurement. A reference fluid flow is required to calibrate the sensor via chemometric analysis.
