1. A system, comprising:
a flowmeter including:
a mixer configured to homogenize a fluid received at an inlet of the flowmeter;
a temperature probe configured to measure a temperature of the fluid;
a differential pressure sensor configured to measure a differential pressure of the fluid across an inlet and an outlet of the mixer, wherein the differential pressure sensor comprises a sensing element configured to measure a pressure of the fluid; and
a Doppler probe configured to transmit a microwave or an ultrasonic wave into the fluid to generate Doppler frequency shift data;
an electromagnetic transmitter configured to transmit an electromagnetic wave into the fluid;
an electromagnetic receiver configured to receive the electromagnetic wave, the electromagnetic receiver configured to generate amplitude-attenuation data and phase-shift data based on the received electromagnetic wave; and
a flowmeter manager configured to:
calculate a velocity of the fluid based on the Doppler frequency shift data;
calculate a density of the fluid based on the differential pressure and the velocity;
calculate a permittivity of the fluid based on the amplitude-attenuation data;
calculate a conductivity of the fluid based on the amplitude-attenuation data and the phase-shift data; and
calculate at least one of a water conductivity, a water permittivity, a water density, or a water salinity based on the permittivity of the fluid, the conductivity of the fluid, the temperature of the fluid, and the pressure of the fluid.
