1. A system for determining a temperature of a supercritical fluid in a closed supercritical fluid cycle, the system comprising:
a conduit in the closed supercritical fluid cycle, the conduit comprising an inside diameter for directing a flow of the supercritical fluid along an axial direction of the conduit;
a supercritical fluid compressor, the supercritical fluid compressor including an inlet connected to the conduit so as to receive the supercritical fluid for compression therein;
a pressure sensor, the pressure sensor mounted on the conduit and configured to measure a pressure value of the supercritical fluid in the conduit;
a first transducer, the first transducer mounted on the conduit and configured to generate and transmit a sonic pulse in the supercritical fluid;
a second transducer, the second transducer mounted on the conduit opposed to the first transducer and configured to receive the sonic pulse; and
a controller, the controller in electronic communication with the pressure sensor, the first transducer, and the second transducer, wherein the controller is configured to determine a speed of sound value in the supercritical fluid based on the sonic pulse and to determine the temperature of the supercritical fluid based on the measured pressure value and the determined speed of sound value in the supercritical fluid directed to the inlet of the supercritical fluid compressor.
