AI summary

A technique facilitates evaluation of a fluid, such as a fluid produced from a well. The technique utilizes a modular and mobile system for testing flows of fluid which may comprise mixtures of constituents. A modular flow meter system comprises a plurality of modules which each have a multiphase flow meter coupled into a flow circuit. The flow circuits of the plurality of modules are selectively connectable to each other via flow connectors. Additionally, portions of the flow circuits may be selectively opened and closed to enable controlled routing of the fluid being tested through the desired multiphase flow meter or meters.
