An embodiment of the present invention may incorporate a physics based approach (hereinafter 'model') to determine the level of the liquid. The model may incorporate the physical properties of the fluids within the container, and measurements of the fluid under consideration. The model may also incorporate data from measuring devices, such as, but not limiting of, a delta-pressure (DP) transmitter. The model may then calculate, within a reasonable level of accuracy, the level of the fluid within the container.

System and method for measuring a level of a liquid in a container

A method for controlling the rate of transfer between operation with gas and liquid fuel types to minimize the time in undesirable operational mode, thereby preventing excessive wear and damage to gas turbine hardware. The method includes completing a fuel prefill for the oncoming fuel type through the fuel system and determining if a total fuel demand for the oncoming fuel type is greater than a predetermined flow rate for the oncoming fuel type. The method also includes selecting a fuel transfer rate and transferring from the offgoing fuel type to the oncoming fuel type at the selected fuel transfer rate. Further, the method includes determining if the offgoing fuel flowrate has decreased below a predetermined flow rate for the offgoing fuel type, selecting a final fuel transfer rate and completing the transfer from offgoing fuel type to oncoming fuel type at a selected final fuel transfer rate.
