A device to determine density includes a housing, a first transducer disposed in the housing at a first position, and a second transducer disposed in the housing at a second position. The second transducer is located a distance from the first transducer. The device also includes a controller that reads a first output from the first transducer, and reads a second output from the second transducer. The controller determines a density of a liquid based on the first output, the second output, and the distance.

An automated resonant waveguide cavity system for determining one or complex permittivity measurements of a sample is provided. The automated resonant waveguide cavity system includes a resonant cavity, a waveguide coupled to the resonant cavity, a programmable network analyzer (PNA) coupled to the waveguide, and a computing device. The computing device includes a memory storing processor executable code for a determination engine and a processor executing the processor executable code to cause the determination engine to obtain data from the PNA. The data is respective to the sample within the resonant cavity. The determination engine further integrates a plurality of analytical and modeling functions in determining the complex permittivity values of the sample from the data.
