A fuel control system () for fuel consumption calculation for a fuel and water mixture is provided. The fuel control system () includes a mixer (), a fuel source () fluidly coupled to the mixer (), the fuel source () being configured to measure a flow of fuel to the mixer (), a water source () fluidly coupled to the mixer (), the water source () being configured to measure a flow of water to the mixer (), and a mixture flow meter () fluidly coupled to the mixer (). The mixture flow meter () is configured to receive and measure properties of a fuel/water mixture from the mixer ().

Fuel consumption calculation of a fuel and water mixture

A method for operating a system configured to consume a fluid, such as engine fuel, having at least two flowmeters is provided. The method includes the step of recirculating a fluid in a closed loop having a supply-side flowmeter and return-side flowmeter, such that substantially no fluid is consumed. Fluid flow is measured in the supply-side flowmeter and the return-side flowmeter. Fluid flow measurements are compared between the supply-side flowmeter and return-side flowmeter, and a first differential zero value based on the difference in the fluid flow measurements between the supply-side flowmeter and return-side flowmeter is determined. A first temperature sensor signal value is received and is associated with the first differential zero value. The first differential zero value associated with the first temperature sensor signal value is stored in a meter electronics.
