This system can measure multiple parameters such as instantaneous moisture content, temperature, pressure, and instantaneous flow rate, and is suitable for automated management in the petroleum and petrochemical industries both domestically and internationally. Widely used in the field of crude oil handover and measurement, it can be applied to oilfield sites with harsh environmental conditions such as measurement rooms, transfer stations, oil gathering stations, and joint stations to solve the measurement problems of oilfield teams. The system is capable of receiving various instrument signals such as flow meters, temperature, pressure, etc., and displaying the collected liquid volume, temperature, pressure, and water content signals in real-time on the software screen. It also accumulates and calculates parameters such as liquid volume, oil volume, and instantaneous water content in real-time; Adopting menu based management and a practical and user-friendly real-time monitoring interface; Equipped with real-time trend curve graph and historical curve query function; Capable of storing and querying data reports; Equipped with alarm function; Adopting a modular structure, it is easy to diagnose, maintain, and upgrade on-site.
