Abstract
A system comprises a differential pressure sensor, a process pressure sensor, a temperature sensor and a microprocessor. The differential pressure sensor is positioned to sense differential pressure along a fluid flow, where fluid properties of the fluid flow have first and second phases separated along a transition curve. The process pressure sensor is positioned to sense a pressure of the fluid flow, and the temperature sensor is positioned to sense a temperature of the fluid flow. The microprocessor is coupled to the temperature sensor and the pressure sensor to determine a flow rate, and the microprocessor generates a diagnostic based on the process pressure and the temperature as compared to the transition curve.
