Abstract
A method for controlling a fluid-flow sensor in the presence of a flowing fluid, the method comprising: applying an electrical bias to the heater element of the fluid-flow sensor, determining a phase of the flowing fluid, and modifying the electrical bias according to the phase of the flowing fluid. A controller for a fluid-flow sensor is also described.
Claims4
A method for controlling a fluid-flow sensor in the presence of a flowing fluid, the method comprising:
- applying an electrical bias to a heater element of the fluid-flow sensor;
- determining a heat transfer coefficient for the heater element;
- comparing the heat transfer coefficient to one or more third known values;
- determining a phase of the flowing fluid based on comparing the heat transfer coefficient to the one or more third known values;
- and
- modifying the electrical bias according to the phase of the flowing fluid.
