System for multiphase (oil-gas-water) flow meter calibration

A multiphase flow meter calibration system, comprising:

• an oil-gas-water separation unit;
• a multiphase fluid inlet, wherein a multiphase fluid mixture flows into the oil-gas-water separation unit through the multiphase fluid inlet;
• a single phase water outlet, wherein the single phase water outlet is in fluid communication with a water section of the oil-gas-water separation unit through a variable flow water pump and a water flow meter;
• a single phase oil outlet, wherein the single phase oil outlet is in fluid communication with an oil section of the oil-gas-water separation unit with a variable flow oil pump and an oil flow meter;
• a phase combination piping joint, wherein the single phase water outlet and the single phase oil outlet are in fluid communication with the phase combination piping joint;
• a gas flow outlet, wherein the gas flow outlet is in fluid communication with a pressurized gas tank through a gas pressure regulator and a gas flow meter;
• the gas flow outlet being in fluid communication with the phase combination piping joint;
• a downstream homogenizer, wherein the downstream homogenizer comprises a homogenizer inlet and a homogenizer outlet;
• a piping outlet of the phase combination piping joint being in fluid communication with the homogenizer inlet;
• the homogenizer outlet being in fluid communication with an inlet of a multiphase flow calibration unit;
• and
• the multiphase flow calibration unit being in fluid communication with the oil-gas-water separation unit.
