Abstract Real-time production monitoring is crucial for maintaining high operating efficiency, optimizing production costs, minimizing production losses, and enabling informed decision-making. Effective production tracking is particularly important in mature heavy oil fields, which often face challenges such as high water cut, intermittent production, and inverse emulsion. This paper presents the technical development of a production meter specifically designed and manufactured to address these requirements. The production meter, tailored for heavy oil and high water cut conditions, utilizes the full pipe section and integrates multiple capacitive and resistive sensors arranged in a spiral array to preserve the flow regime and minimize interference and backpressure. The meter is capable of determining not only the water cut but also the flow regime (laminar or turbulent), emulsion characteristics, water salinity, intermittent or stable flow conditions, and velocity across a wide range using turbine, venturi, and thermal decay methods. Multiple case studies are presented to validate the performance of the measurement device. Unlike conventional methods that rely on radioactive sources or flow restriction, this low-cost meter accurately measures oil and water production, flow regime, water salinity, and production type. The meter's performance under varying conditions demonstrates low pressure drop, unrestricted flow, and effective measurement in laminar and turbulent flow regimes, including inverse emulsion scenarios. This paper introduces a cost-effective alternative for measuring production and water cut in mature heavy oil fields characterized by high water cut and inverse emulsion flow. Examples and typical responses are provided as guidelines for production engineers
