Abstract
This paper introduces the application of Venturi flow meter for wet gas flow measurement. Wet gas which is a gas containing small amount of liquid is mostly encountered in gas wells where the extracted gas has water and condensate inside. Venturi flow meters which originally were introduced for single phase flow measurement are adapted for wet gas measurement. In this paper, we elaborate using of Venturi meter as a device for measuring wet gas flow and explain versatile methods for correcting the reading of Venturi tube for wet gas application. Tracer injection method is introduced as a manual tool for measuring water and condensate flow rate in wet gas fluid. Also radioactive measuring method has been introduced as an automatic method for measuring the ratio between gas, water and condensate in wet gas fluid. Finally different aspects of using radioactive sources are elaborated.
