The Contrec Model 515 (Application FN01) is a high-accuracy net oil flow computer engineered specifically for upstream petroleum production fields to compute net oil and water content in wet crude streams. This high-performance instrument interfaces directly with the frequency output of a Coriolis mass flowmeter while gathering analog temperature and density sensor measurements to execute real-time water cut tracking. Volume corrections are processed in absolute compliance with global ASTM D1250-04 standards by comparing live temperature and density data against programmed reference densities for both the oil and water phases. Built to provide complete fiscal accountability in harsh oilfield extraction environments, the computer features a weather-sealed IP65 frontal fascia to withstand severe climate variations. With built-in Modbus RTU RS-485 connectivity, isolated 4-20mA retransmission, and an adjustable 8-24V DC sensor supply, the Contrec 515 FN01 serves as a definitive B2B processing core for separator and well testing manifolds.

Key Product Features

ASTM D1250-04 Net Oil Resolution: Combines mass flow data with live density/temperature inputs to resolve real-time water cut percentages and extract net oil volumes.
Mass Flowmeter Input Integration: Optimized to accept high-speed pulse train and frequency signals directly from industrial Coriolis mass flow instruments.
Onboard Sensor Power Supply: Reduces field wiring loops by offering a front-panel adjustable 8-24V DC output voltage providing up to 50mA to directly power field instrumentation.
Multi-Variable Alphanumeric Interface: Backlit display showcases real-time total mass, mass flow, net oil volume, net oil flow, live mixture density, and water cut %.
Robust Data Logging Trail: Features an integrated non-volatile memory block and Real Time Clock (RTC) capturing over 1,000 logging entries for rigorous production audits.
