Abstract
A fluid flow meter is provided that generates a pulsed output to account for viscosity variations. The fluid flow meter includes a controller with a data storage that is configured to store correlations of fluid pressure, volumetric flow rate and pulse frequency for different viscosities, based on a calibration of the fluid flow meter. A pressure sensor is configured to be connected in parallel to a flow chamber of the fluid flow meter for measuring the pressure across the flow chamber.
