Claim 8:
9. A method for monitoring slosh of a liquid within a propellant tank without requiring use of a moving part, the method comprising:
establishing a specified electromagnetic field configuration within the tank using an electromagnetic transmitter at a first location, including using a swept-frequency excitation scheme;
sensing an electromagnetic field established within the tank by the electromagnetic transmitter using an electromagnetic receiver at a different second location;
using a control circuit, determining a characteristic of a spatial configuration of the liquid using the sensed electromagnetic field; and
using the control circuit, determining a position or a distribution of the liquid using at least one of a magnitude value, a phase value, a frequency value, or a quality factor value associated with a frequency-domain resonance excited by the electromagnetic transmitter.
