The first practical coriolis mass flowmeter was introduced in 1977. Today, there are several manufacturers which offer various coriolis mass flowmeters with different sensing tube configurations and geometry. These meters continue to evolve, gain wide acceptance, and are used in the chemical, petroleum, food and beverage industries because of the several features that they posses over other types of flow measurement devices. This paper presents a performance evaluation of three types of coriolis mass flowmeters: U-tube, modified U-tube, and straight tube meters. These meters were individually tested in a compact multiphase test unit (WellComp) located in an onshore area of a field in Saudi Arabia. The test results obtained from these meters were compared with simultaneous data obtained from turbine meters installed in a conventional test separator.
