Abstract
A flow sensor including a fluid flow path, a first sensor configured to determine a first measurement of a thermal diffusivity and/or a viscosity of a fluid in the fluid flow path, a second sensor configured to determine a second measurement of a fluid flow velocity and/or a volumetric flow rate of the fluid in the fluid flow path, and at least one processor configured to adjust the second measurement based on the first measurement. A method including receiving fluid in a fluid flow path of a flow sensor, determining a first measurement of a thermal diffusivity and/or a viscosity of the fluid in the fluid flow path, determining a second measurement of a fluid flow velocity and/or a volumetric flow rate of the fluid in the fluid flow path, and adjusting the second measurement based on the first measurement.
