Abstract
A method of sensing a fluid. The method includes determining a slope based on a first measurement of a first ultrasonic pulse traveling through the fluid, a second measurement based on a second ultrasonic pulse traveling through the fluid, a first temperature of the fluid, and a second temperature of the fluid. The method further includes comparing the slope to a predetermined slope and the first measurement to a predetermined measurement.
