1. A Coriolis flow meter for controlling a viscosity in a fuel control system with the Coriolis flow meter, the Coriolis flow meter comprising:
a meter assembly fluidly coupled to a fuel line between a temperature control unit and an engine;
a meter electronics communicatively coupled to the meter assembly, wherein the meter electronics is configured to:
measure a density of the fuel with the meter assembly;
measure a temperature control unit viscosity of the fuel using a temperature control unit coupled to the fuel line;
determine a Coriolis flow meter viscosity of the fuel based on the density of the fuel using an empirically determined viscosity-density relationship of the fluid;
generate a signal based on the Coriolis flow meter viscosity of the fuel; and
provide the signal to the temperature control unit configured to control an engine viscosity of the fuel by controlling the temperature of the fuel provided to the Coriolis flow meter based on the Coriolis flow meter viscosity and the temperature control unit viscosity to compensate for heat loss between the Coriolis flow meter and the temperature control unit.
