Systems and methods for configuring flow meters

A system for configuring flowmeters, the system comprising:

• one or more physical processors configured by machine-readable instructions to:
• obtain measured values of fluid properties for oil, gas, and water in a pipe at an operating temperature and an operating pressure;
• perform fluid phase equilibrium modeling for the pipe based on the measured values of fluid properties for oil, gas, and water in the pipe at the operating temperature and the operating pressure to determine modeled values of fluid properties for oil, gas, and water in the pipe at different operating temperatures and different operating pressures;
• generate a fluid property look-up table based on the modeled values of fluid properties for oil, gas, and water in the pipe at the different operating temperatures and the different operating pressures, the fluid property look-up table establishing correspondence between values of operating temperatures and operating pressures and values of fluid properties for oil, gas, and water;
• and
• configure a flowmeter to directly use the fluid property look-up table to measure flowrates of oil, gas, and water in the pipe, wherein the flowmeter interpolates between the values of operating temperatures and operating pressures and the values of fluid properties for oil, water, and gas in the fluid property look-up table to determine applicable values of fluid properties for oil, water, and gas in measuring the flowrates of oil, water, and gas in the pipe.
